    Chronic Intestinal Pseudo-Obstruction (CIPO) is a rare syndrome characterized by chronic intestinal dilation and dysmotility in the absence of mechanical obstruction. A definite diagnosis of CIPO can only be made after histological examination of intestinal tissues. The present case describes a CIPO in a 2.5-year-old Bernese Mountain dog with a history of recurrent gastro-intestinal complaints suggestive for pseudo-obstruction. Histological lesions of small intestinal samples consisted of se...

    Full Text Available A genome-wide association study for canine hip dysplasia (CHD and canine elbow dysplasia (CED using the Illumina canine high density bead chip had been performed for 174 Bernese mountain dogs. General and mixed linear model analysis identified two different regions with single nucleotide polymorphisms (SNPs on dog chromosome (CFA 14 significantly associated with CHD and a further significantly CHD-associated region on CFA37. For CED, four SNPs on CFA11 and 27 were significantly associated. The identified SNPs of four associated regions included nearby candidate genes. These possible positional candidates were the genes PON2 on CFA14 and FN1 on CFA37 for CHD and the genes LMNB1 on CFA11 and WNT10B on CFA27 for CED.

    The aim of this study was the multivariate prediction of breeding values for canine hip dysplasia (CHD), elbow dysplasia (ED) and humeral osteochondrosis (OCD) for Bernese mountain dogs of the Schweizer Sennenhund-Verein für Deutschland e. V. (SSV). For the analysis the pedigrees of eight generations and radiographic screening results of the birth cohorts from 1995-2008 were used. The number of dogs with scores for CHD was 5513, for ED 5175 and OCD 1240. Breeding values were multivariately predicted using a mixed linear model for CHD, ED and OCD as well as for the occurrence of a fragmented coronoid process of the medial ulna (FCP) and the ED-score without FCP. The pedigree breeding value (eRZWp) which is used as the selection criterion reached a reliability to predict the phenotype of the offspring at 2.8-2.9% for CHD, 2.9% for ED, 1.1% for ED without FCP, 1.8% for FCP and 0.8-1.3% for OCD. The reason for the low predictive value of the eRZW(P) is caused by the very high influence of the own performance of the animal and the very uniform distribution of contributions of the breeding values of the relatives.These results indicate that even a multivariate prediction of breeding values does not lead to a faster progress in breeding against CHD and ED, however, does allow breeding against OCD in the Bernese mountain dog. In comparison to phenotypic selection, there is some improvement in the selection response when using breeding values. Due to the general low predictive power of breeding values better approaches for selection of future breeding animals are urgently warranted to achieve improvements in breeding Bernese mountain dogs.

    Neonatal neosporosis is a challenging disease to diagnose in neonatal and young puppies because the first signs of this condition may not be strongly suggestive of an infectious aetiology. Within two weeks of birth, three of four pups died with a subacute clinical course, some with dyspnea, some with diarrhoea and some with neurologic signs. Neosporosis was diagnosed post-mortem, but only after microscopic examination of tissues collected at necropsy. Histological findings consisted of (i) necrotizing, diffuse interstitial pneumonia associated with intralesional protozoa and (ii) necrotizing multifocal myocarditis with mineralization and intralesional protozoa. No significant alterations were found in the cerebrum or cerebellum (spinal cord was not examined). Immunohistochemistry confirmed protozoal stages and cysts were Neospora caninum. Immunohistochemistry for Toxoplasma gondii was negative. Lung and heart were the most severely affected tissues with large numbers of free zoites, BAG5 positive bradyzoites and tissue cysts of N. caninum further confirmed by N. caninum-specific quantitative real-time PCR. One affected pup which displayed knuckling, ataxia and diarrhoea were treated with trimethoprim sulfadiazine and clindamycin, and made a complete recovery. This surviving pup (at 8 weeks-of-age) and dam were both positive for N. caninum antibody (reciprocal titres 4096 and 256, respectively). Three other intact bitches on the same property were seropositive for N. caninum, suggesting horizontal transmission and a common source of infection, possibly due to consumption of infected meat. Analysis using microsatellite-10 (MS10) demonstrated that multiple strains of N. caninum were present. It was likely that all MS10 N. caninum strains were transplacentally transmitted from dam to pups. This is the first time that multiple N. caninum strains have been demonstrated to be vertically transmitted in dogs. N. caninum should be considered in the differential diagnosis for

  9. Craniomandibular osteopathy in two Pyrenean mountain dogs

    International Nuclear Information System (INIS)

    Craniomandibular osteopathy was diagnosed in two Pyrenean mountain dogs with a history of mandibular swelling, pain, fever and, in dog 1, lameness. Radiographs demonstrated extensive, active new bone formation on the ventral aspect of the mandibular bodies of both dogs. Dog 2 responded well to treatment but dog 1 was euthanased owing to severe pain, dysphagia and unsuccessful treatment. The mandibles were examined by means of back-scattered scanning electron microscopy and a well arranged mineralised trabecular network of chondroid tissue and woven bone was observed. The mandibular cortical bone under the areas of periosteal proliferation was also affected, showing a looseness of the characteristic compact appearance of lamellar bone. This is the first report of craniomandibular osteopathy in this breed

    Because of unpredictable corneal changes, evisceration and implantation of a silicone prosthesis does not always lead to a satisfying cosmetic result. This paper describes the use of an intraocular silicone prosthesis in combination with an extraocular glass prosthesis and shows a followup of two and a half years in a nonexperimental study. An intraocular silicone prosthesis was implanted after evisceration of the left eye in a five-month-old Bernese mountain dog. A glass prosthesis was fitte...

  12. Comparison of two classification protocols in the evaluation of elbow dysplasia in the dog

    International Nuclear Information System (INIS)

    The incidence of elbow disease based solely on arthrosis (ARTH) score was compared with a protocol using a combination of ARTH score plus a score for primary lesions (ED score). The population of dogs studied included 425 Bernese mountain dogs and 22 dogs of other breeds. The overall agreement between the two systems was high. However, 12 per cent of ARTH-score negative cases were positive using the ED score. This difference was statistically significant (P < 0.005). The female:male ratio of the dogs missed using the ARTH score was 2:1. The proportion of dogs affected with arthrosis increased with age, male dogs being affected more frequently. The development of arthrosis depends not only on age and breed, but probably also on gender. Thus, screening for elbow dysplasia should be based on at least two radiographic projections, including arthrosis and primary lesions. As the vast majority of dogs in this study were Bernese mountain dogs, conclusions are valid only for this breed

    2006-01-01

    Immune-mediated central nervous system inflammation is described in a series of 12 juvenile boxer dogs. A diagnosis of steroid-responsive meningitis-arteritis was made based on the clinical presentation and on diagnostic findings. The boxer breed was at a higher risk for this inflammatory condition than other breeds. Long-term follow-up (>2 years) confirmed a better prognosis in this breed than in the beagle and the Bernese mountain dog. Complete resolution of clinical signs without significant deficits or recurrences was obtained in all cases. Early clinical recognition and immunosuppressive treatment resulted in a better response and complete resolution of the disorder. PMID:16822766

    In order to determine the prevalence of hip dysplasia (HD) from radiographs that were submitted for authorative grading, and its changes over the time in 31 breeds of dogs in France, a 14 year-retrospective study was conducted. Significant differences were observed between breeds, with HD prevalence ranging from 59.7% (Cane Corso) to 3.9% (Siberian Husky). When comparing the 1993-1999 with the 2000-2006 period in 15 breeds, a significant decrease in HD prevalence was detected in Berger Picard, Bernese Mountain dog, Briard, Gordon Setter, White Swiss Sheepdog and Rottweiler. Modifications observed in the other breeds were not statistically significant. PMID:18288340

  16. Measurements on the lumbosacral junction in normal dogs and those with cauda equina compression

    International Nuclear Information System (INIS)

    Comparative measurements on lateral plain radiographs of the lumbosacral junction in neutral position, in flexion, and in extension, were made of 41 clinically and radiographically normal dogs (21 German shepherd dogs [GSDs], 12 Bernese mountain dogs, eight labrador retrievers) and 58 GSDs with clinical signs of cauda equina compression due to malformation and, or, malarticulation. The comparison of these measurements between sexes, between normal and affected GSDs and between normal GSDs and the two other breeds of dogs showed several statistically significant results. One was that the affected GSDs showed a reduced flexion ability at this junction compared to the normal ones. However, no difference was observed in the degree of sub-luxation of the sacrum between normal and affected GSDs. It was concluded that plain radiographs of the lumbosacral junction in flexion could help in determining a reduced flexion ability, which could be a characteristic of the GSD with cauda equina compression

    Hovius, K E; Houwers, D J

    2007-08-15

    This paper discusses the problem of diagnosing borreliosis (Lyme disease) in dogs. A prospective cohort study in the Kempen district, a known Borrelia focus in The Netherlands, showed that dogs with the presumptive symptoms of borreliosis, episodic malaise and lameness, had significantly higher and longer lasting anti-Borrelia IgG titers than asymptomatic dogs. A small part of these dogs also had antibodies directed against the IR6 (C6) antigen which indicates persistent active Borrelia infection. A few typical case histories are presented. Dogs with episodic malaise and lameness with persistent high IgG titers are suspect of suffering from borreliosis. IR6 antibodies make this diagnosis likely. Initially, such patients should be treated with doxycyclin (10 mg/kg 1dd) for 10 days. If the symptoms recurr within a few months, a longer treatment (eg 6 weeks) should be considered. Bernese mountain dogs were strongly over-represented among the borreliosis patients in the cohort study and most high titered samples among those submitted for--diagnostic--serology appear to come from this breed, which suggests that these dogs have difficulties with clearing this tick-borne infection.

    An 81-year-old man died unexpectedly from a cardiac cause. His wife, who lived in the same house and suffered from Alzheimer's disease, did not realize his death. When the body was found at the foot of the stairs 2-3 days afterwards, extensive soft tissue defects with notched wound edges, but no signs of vitality, were observed on the head and neck. The site where the body was found showed almost no traces of blood. In view of the injuries and their obviously post-mortem origin it was assumed that they had been caused by the man's Appenzell mountain dog which also lived in the house. By means of DNA typing, swabs from the wound edges of the soft-tissue defects could be assigned to the deceased's dog. PMID:19432090

    Dogs were experimentally inoculated with Rickettsia rickettsii (canine origin) in order to compare the efficacies of azithromycin and trovafloxacin to that of the current antibiotic standard, doxycycline, for the treatment of Rocky Mountain spotted fever. Clinicopathologic parameters, isolation of rickettsiae in tissue culture, and PCR amplification of rickettsial DNA were used to evaluate the response to therapy or duration of illness (untreated infection control group) in the four groups. Concentrations of the three antibiotics in plasma and blood cells were measured by high-performance liquid chromatography. Doxycycline and trovafloxacin treatments resulted in more-rapid defervescence, whereas all three antibiotics caused rapid improvement in attitudinal scores, blood platelet numbers, and the albumin/total-protein ratio. Based upon detection of retinal vascular lesions by fluorescein angiography, trovafloxacin and doxycycline substantially decreased rickettsia-induced vascular injury to the eye, whereas the number of ocular lesions in the azithromycin group did not differ from that in the infection control group. As assessed by tissue culture isolation, doxycycline resulted in the earliest apparent clearance of viable circulating rickettsiae; however, rickettsial DNA could still be detected in the blood of some dogs from all four groups on day 21 postinfection, despite our inability to isolate viable rickettsiae at that point. As administered in this study, trovafloxacin was as efficacious as doxycycline but azithromycin proved less efficacious, possibly due to the short duration of administration. PMID:10103185

Logistic regression analysis was used for studying the relationships  between breed, sex, age of dogs at screening and HD diagnosis with the outcome of the diagnosis for ED. Prevalence of  ED (ED score ≥ 1 for the pool of breeds involved was 25%, and Labrador Retriever (17% and Rottweiler (40% showed,  respectively, the lowest and the highest prevalence of ED among breeds in the study. Prevalence of HD (grades C or high-  er approached 15%. When compared to other breeds, Rottweiler and Bernese Mountain dogs showed significantly high-  er risk to be affected by ED (odds ratio 3.2 and 3.0, respectively. Conversely, sex did not significantly affect the onset  of ED. When compared to the youngest group of dogs at screening (average: 14 months, the oldest group of screened  dogs (average: 40 months exhibited a significantly higher risk of being diagnosed as affected by ED (odds ratio: 1.9.  A negative status of hip joints appeared positively associated with a negative status of elbow joints, and dogs diagnosed  as affected by HD had a 40% increased risk of being diagnosed as affected by ED. In conclusion, results from this study  demonstrated that ED has a noticeable prevalence in some Italian dog populations, particularly in heavy breeds.  Screening of dogs for ED appeared feasible and should be performed

  3. Clinical presentation, convalescence, and relapse of rocky mountain spotted fever in dogs experimentally infected via tick bite.

    Michael L Levin

    Full Text Available Rocky Mountain spotted fever (RMSF is a tick-borne disease caused by R. rickettsii in North and South America. Domestic dogs are susceptible to infection and canine RMSF can be fatal without appropriate treatment. Although clinical signs of R. rickettsii infection in dogs have been described, published reports usually include descriptions of either advanced clinical cases or experimental infections caused by needle-inoculation of cultured pathogen rather than by tick bite. The natural progression of a tick-borne R. rickettsii infection has not been studied in sufficient detail. Here, we provide a detailed description of clinical, hematological, molecular, and serological dynamics of RMSF in domestic dogs from the day of experimental exposure to infected ticks through recovery. Presented data indicate that neither the height/duration of fever nor detection of rickettsial DNA in dogs' blood by PCR are good indicators for clinical prognosis. Only the apex and subsequent subsidence of neutrophilia seem to mark the beginning of recovery and allow predicting a favorable outcome in Rickettsia-infected dogs, even despite the continuing persistence of mucosal petechiae and skin rash. On the other hand the appropriate (doxycycline antibiotic therapy of sufficient duration is crucial in prevention of RMSF relapses in dogs.

  5. Bernese periacetabular osteotomy for hip dysplasia: Surgical technique and indications.

    2016-05-18

    For young, active patients with healthy hip cartilage, pelvic osteotomy is a surgical option in to address hip pain and to improve mechanical loading conditions related to dysplasia. Hip dysplasia may lead to arthrosis at an early age due to poor coverage of the femoral head and abnormal loading of the joint articulation. In patients with symptomatic dysplasia and closed triradiate cartilage (generally over age 10), including adolescents and young adults (generally up to around age 40), the Bernese periacetabular osteotomy (PAO) is a durable technique for addressing underlying structural deformity. The PAO involves a modified Smith-Petersen approach. Advantages of the Bernese osteotomy include preservation of the weight-bearing posterior column of the hemi-pelvis, preservation of the acetabular blood supply, maintenance of the hip abductor musculature, and the ability to effect powerful deformity correction about an ideal center of rotation. There is an increasing body of evidence that preservation of the native hip can be improved through pelvic osteotomy. In contrast to hip osteotomy and joint preservation, the role of total hip arthroplasty in young, active patients with correctable hip deformity remains controversial. Moreover, the durability of hip replacement in young patients is inherently limited. Pelvic osteotomy should be considered the preferred method to address correctable structural deformity of the hip in the young, active patient with developmental dysplasia. The Bernese PAO is technically demanding, yet offers reproducible results with good long-term survivorship in carefully selected patients with preserved cartilage and the ability to meet the demands of rehabilitation.

  6. A 33,000-year-old incipient dog from the Altai Mountains of Siberia: evidence of the earliest domestication disrupted by the Last Glacial Maximum.

    Directory of Open Access Journals (Sweden)

    Nikolai D Ovodov

    Full Text Available BACKGROUND: Virtually all well-documented remains of early domestic dog (Canis familiaris come from the late Glacial and early Holocene periods (ca. 14,000-9000 calendar years ago, cal BP, with few putative dogs found prior to the Last Glacial Maximum (LGM, ca. 26,500-19,000 cal BP. The dearth of pre-LGM dog-like canids and incomplete state of their preservation has until now prevented an understanding of the morphological features of transitional forms between wild wolves and domesticated dogs in temporal perspective. METHODOLOGY/PRINCIPAL FINDING: We describe the well-preserved remains of a dog-like canid from the Razboinichya Cave (Altai Mountains of southern Siberia. Because of the extraordinary preservation of the material, including skull, mandibles (both sides and teeth, it was possible to conduct a complete morphological description and comparison with representative examples of pre-LGM wild wolves, modern wolves, prehistoric domesticated dogs, and early dog-like canids, using morphological criteria to distinguish between wolves and dogs. It was found that the Razboinichya Cave individual is most similar to fully domesticated dogs from Greenland (about 1000 years old, and unlike ancient and modern wolves, and putative dogs from Eliseevichi I site in central Russia. Direct AMS radiocarbon dating of the skull and mandible of the Razboinichya canid conducted in three independent laboratories resulted in highly compatible ages, with average value of ca. 33,000 cal BP. CONCLUSIONS/SIGNIFICANCE: The Razboinichya Cave specimen appears to be an incipient dog that did not give rise to late Glacial-early Holocene lineages and probably represents wolf domestication disrupted by the climatic and cultural changes associated with the LGM. The two earliest incipient dogs from Western Europe (Goyet, Belguim and Siberia (Razboinichya, separated by thousands of kilometers, show that dog domestication was multiregional, and thus had no single place of

    1998-07-01

    Full Text Available Elbow dysplasia is a non-specific term denoting abnormal development of the elbow. Elbow dysplasia encompasses the clinical and radiographic manifestation of ununited anconeal process, fragmented medial coronoid process, osteochondritis dissecans, erosive cartilage lesions and elbow incongruity. The net result is elbow arthrosis, which may be clinically inapparent or result in marked lameness. These conditions may be diagnosed by means of routine or special radiographic views and other imaging modalities, or the precise cause of the arthrosis or lameness may remain undetermined. Breeds most commonly affected are the rottweiler, Bernese mountain dog, Labrador and golden retriever and the German shepherd dog. Certain breeds are more susceptible to a particular form of elbow dysplasia and more than 1 component may occur simultaneously. The various conditions are thought to result from osteochondrosis of the articular or physeal cartilage that results in disparate growth of the radius and ulna. Heritability has been proven for this polygenic condition and screening programmes to select suitable breeding stock have been initiated in several countries and have decreased the incidence of elbow dysplasia.

    Preparatory works for resuming operational calculations of the Earth rotation parameters based on the results of satellite laser ranging data processing (LAGEOS 1, LAGEOS 2) are to be completed in the Main Metrology Centre Of The State Time And Frequency Service (VNIIFTRI) in 2014. For this purpose BERNESE 5.2 software (Dach & Walser, 2014) was chosen as a base software which has been used for many years in the Main Metrological Centre of the State Time and Frequency Service to process phase observations of GLONASS and GPS satellites. Although in the BERNESE 5.2 software announced presentation the possibility of the SLR data processing is declared, it has not been fully implemented. In particular there is no such an essential element as corrective action (as input or resulting parameters) in the local time scale ("time bias"), etc. Therefore, additional program blocks have been developed and integrated into the BERNESE 5.2 software environment. The program blocks are written in Perl and Matlab program languages and can be used both for Windows and Linux, 32-bit and 64-bit platforms.

  15. Modelling spatial concordance between Rocky Mountain spotted fever disease incidence and habitat probability of its vector Dermacentor variabilis (American dog tick

    Directory of Open Access Journals (Sweden)

    Samuel F. Atkinson

    2012-11-01

    Full Text Available The spatial distribution of Dermacentor variabilis, the most commonly identified vector of the bacterium Rickettsia rickettsii which causes Rocky Mountain spotted fever (RMSF in humans, and the spatial distribution of RMSF, have not been previously studied in the south central United States of America, particularly in Texas. From an epidemiological perspective, one would tend to hypothesise that there would be a high degree of spatial concordance between the habitat suitability for the tick and the incidence of the disease. Both maximum-entropy modelling of the tick’s habitat suitability and spatially adaptive filters modelling of the human incidence of RMSF disease provide reliable portrayals of the spatial distributions of these phenomenons. Even though rates of human cases of RMSF in Texas and rates of Dermacentor ticks infected with Rickettsia bacteria are both relatively low in Texas, the best data currently available allows a preliminary indication that the assumption of high levels of spatial concordance would not be correct in Texas (Kappa coefficient of agreement = 0.17. It will take substantially more data to provide conclusive findings, and to understand the results reported here, but this study provides an approach to begin understanding the discrepancy.

  16. Elements in Mud and Snow in the Vicinity of the DeLong Mountain Regional Transportation System Road, Red Dog Mine, and Cape Krusenstern National Monument, Alaska, 2005-06

    Science.gov (United States)

    Brumbaugh, William J.; May, Thomas W.

    2008-01-01

    A small number of mud, road bed soil, and snow samples were collected in 2005 and 2006 to assess metal concentrations and loadings to areas adjacent to the DeLong Mountain Regional Transportation System (DMTS) road in northwest Alaska. The DMTS road is used by large trucks to transport lead and zinc concentrates from Red Dog Mine to the shipping facility at Red Dog Port; it traverses 32 kilometers of land in Cape Krusenstern National Monument (CAKR). Mud collected in the summer of 2005 from wheel-wells of two passenger vehicles used for transport between Red Dog Mine and the port facility were enriched in cadmium, lead, and zinc by factors of about 200 to 800 as compared with mud collected from a vehicle stationed in Kotzebue, Alaska, whereas DMTS road bed soil samples were enriched by factors of 6 to 12. Thus, as of 2005, dispersal of mine ore wastes or concentrates by vehicles appeared to remain a potential source of metals along the DMTS road. Compared to snow samples obtained near a gravel road located near Kotzebue, Alaska, metal loadings estimated from individual snow samples collected in CAKR in April 2006 near three creeks, 13 to 50 meters from the road, were greater by factors of 13 to 316 for cadmium, 28 to 589 for lead, and 8 to 195 for zinc. When averaged for all three creek locations, mean loadings of cadmium, lead, and zinc calculated from snow samples collected at a nominal distance of 15 meters to the north of the road were 0.63, 34, and 89 milligrams of metal per square meter, respectively. Variability of particulate and metal loadings between individual samples and the three creek locations probably was affected by localized meteorological conditions and micro-topography on the snow drift and scour patterns, but road orientation on attainable truck speeds also might have been a factor. Results indicated that the ?port effect?, previously attributed to fugitive metal-enriched dusts stemming from concentrate transfer operations at the port facility

    Full Text Available Abstract Background The picture of dog mtDNA diversity, as obtained from geographically wide samplings but from a small number of individuals per region or breed, has revealed weak geographic correlation and high degree of haplotype sharing between very distant breeds. We aimed at a more detailed picture through extensive sampling (n = 143 of four Portuguese autochthonous breeds – Castro Laboreiro Dog, Serra da Estrela Mountain Dog, Portuguese Sheepdog and Azores Cattle Dog-and comparatively reanalysing published worldwide data. Results Fifteen haplotypes belonging to four major haplogroups were found in these breeds, of which five are newly reported. The Castro Laboreiro Dog presented a 95% frequency of a new A haplotype, while all other breeds contained a diverse pool of existing lineages. The Serra da Estrela Mountain Dog, the most heterogeneous of the four Portuguese breeds, shared haplotypes with the other mainland breeds, while Azores Cattle Dog shared no haplotypes with the other Portuguese breeds. A review of mtDNA haplotypes in dogs across the world revealed that: (a breeds tend to display haplotypes belonging to different haplogroups; (b haplogroup A is present in all breeds, and even uncommon haplogroups are highly dispersed among breeds and continental areas; (c haplotype sharing between breeds of the same region is lower than between breeds of different regions and (d genetic distances between breeds do not correlate with geography. Conclusion MtDNA haplotype sharing occurred between Serra da Estrela Mountain dogs (with putative origin in the centre of Portugal and two breeds in the north and south of the country-with the Castro Laboreiro Dog (which behaves, at the mtDNA level, as a sub-sample of the Serra da Estrela Mountain Dog and the southern Portuguese Sheepdog. In contrast, the Azores Cattle Dog did not share any haplotypes with the other Portuguese breeds, but with dogs sampled in Northern Europe. This suggested that the

Twenty-one dogs yawned when they observed a human yawning, but control mouth movements did not elicit yawning from any of them. The presence of contagious yawning in dogs suggests that this phenomenon is not specific to primate species and may indicate that dogs possess the capacity for a rudimentary form of empathy. Since yawning is known to modulate the levels of arousal, yawn contagion may help coordinate dog-human interaction and communication. Understanding the mechanism as well as the function of contagious yawning between humans and dogs requires more detailed investigation. PMID:18682357

    Three hundred and ninety-seven randomly selected households were interviewed by telephone to determine the numbers and management of owned cats and dogs in the Teramo Province of Italy. The households were selected using stratified random sampling for each municipality; municipalities were combined into coastal, central hills and mountain regions for analysis. The interviews were completed during May and June of 2004 with a response rate of 74% (397/536). Forty-six percent of households (n=181) owned pets; 15% of all households (n=60) owned cats and 33% (n=130) owned dogs. Twenty-seven of these households (7%) owned both cats and dogs. Data were provided on 91 cats evenly divided between males and females. The median age was 3 years (range 0.2-10 years). Forty-one percent of cats (36/87) entered the household as strays. Nearly half lived entirely outside. Seventy percent (62/88) had visited a veterinarian at least once; 43% (39/91) were sterilized. About 1/3 had had a litter and all litters were considered accidental rather than planned. Age, indoor/outdoor status, veterinarian visit and region were all associated with sterilization. Age, confined to a yard, veterinary visit and region were associated with allowing the cat to roam freely. Data were provided on 182 dogs. Sixty-two percent (113/181) were male, with a median age of 4 years (range newborn to 17 years) and 40% (72/181) were purebred. Almost half were acquired as a gift. Sixty-two percent (112/180) were kept entirely outside despite the fact that 82% (147/180) were considered companions rather than working dogs. Almost all of the dogs had been to a veterinarian at least once; only 20% (n=29) were sterilized. Male dogs were significantly less likely to be sterilized than females. Almost half the dogs had had at least one litter. Seventy-six percent (137/180) of dogs knew some basic commands. Sex, source and training to sit/stay/come were significantly associated with whether the dog was sterilized. Dog

BigDog is aimed at the mission of a mechanical mule - a category with few competitors to date: power autonomous quadrupeds capable of carrying significant payloads, operating outdoors, with static and dynamic mobility, and fully integrated sensing. BigDog is about 1 m tall, 1 m long and 0.3 m wide, and weighs about 90 kg. BigDog has demonstrated walking and trotting gaits, as well as standing up and sitting down. Since its creation in the fall of 2004, BigDog has logged tens of hours of walking, climbing and running time. It has walked up and down 25 & 35 degree inclines and trotted at speeds up to 1.8 m/s. BigDog has walked at 0.7 m/s over loose rock beds and carried over 50 kg of payload. We are currently working to expand BigDog's rough terrain mobility through the creation of robust locomotion strategies and terrain sensing capabilities.

    Earlier studies have shown variation among experimental attempts to establish whether human monozygotic twins that are genetically identical also have identical individual scents. In none of the cases were the dogs able to distinguish all the individual scents of monozygotic twins living in the same environment if the scents were presented to them separately. Ten specially trained police German Shepherd dogs of three Czech Republic Police Regional Headquarters were used for scent identification in our study. The dogs were supposed to match scents of two monozygotic pairs (5 and 7 years old) and two dizygotic twin pairs (8 and 13 years old). Scents were collected on cotton squares stored in glass jars. Dog handlers were blind to the experiment details. In each trial (line-up), one scent was used as a starting scent and the dog was then sent to determine if any of the 7 presented glass jars contained a matching scent. Scents of children of similar ages were used as distractors. In the matching procedure, the dogs matched correctly the scent of one twin with the other, as well as two scents collected from every single identical and non-identical twin to prove their efficacy and likewise, the presence of the matching twin scent in any given glass jar. All dogs in all trials distinguished correctly the scents of identical as well as non-identical twins. All dogs similarly matched positively two scents collected from the same individuals. Our findings indicated that specially trained German Shepherd dogs are able to distinguish individual scents of identical twins despite the fact that they live in the same environment, eat the same food and even if the scents are not presented to them simultaneously.

    Cholangiohepatitis was diagnosed in a dog with a 4-day history of anorexia, vomiting, fever, and icterus. Additional findings included signs of depression, dehydration, hepatosplenomegaly, and abdominal discomfort. Exploratory laparotomy was performed, and specimens of liver, spleen, and bile were obtained. Histologic evaluation of liver and spleen revealed acute, suppurative cholangio-hepatitis and splenitis, respectively. Cultures of liver and bile yielded Klebsiella sp. The dog responded to rehydration and intravenous administration of chloramphenicol. Although uncommon, cholangiohepatitis should be suspected in dogs with anorexia, fever, vomiting, icterus, and signs of abdominal discomfort. Definitive diagnosis requires bacterial cultures of liver and bile. Administration of an appropriate antibiotic should resolve clinical signs. PMID:1624352

    Full Text Available Although the biology and ecology of the arthropod vectors are different, some factors, such as global warming, the increasing abundance of mosquitoes, the movement of domestic hosts, and the abundance of wild reservoirs, can act as favourable factors for the distribution of infections. The aim of this study was to determine the prevalence of Dirofilaria immitis infection in shepherd dogs living in the high altitude of mountainous area (i.e.1200 meters above the sea level. The study group was comprised of 160 shepherd dogs living in 4 mountainous regions (Targavar, Margavar, Kolshin and Hovarchin of west Azerbaijan where continuous movement of sheep and goat flocks resulted to have a little information about shepherd dogs in these regions. Additionally, arduous pathways have made impossible any access by car to some territories of these areas. The dogs were mostly mixed raced with different ages (from 1 to 10 years and sexes (male = 136, female = 24. Blood samples were collected from cephalic vein. Direct thin and thick blood smears and modified knott’s technique were used for detecting D.immitis microfilariae and other blood parasites. The results indicated that 40 (25 % of dogs were infected with D. immitis microfilariae. In examination of the dogs, no severe life threatening feature of the disease was diagnosed. There were no significant differences (P > 0.05 of Dirrofilaria infection among gender, age groups and geographical areas. High prevalence of asymptomatic Dirrofilariasis in shepherd dogs in this area highlights the need of controlling and preventive programs.

    The daytime summer phenomenon of the mesoscale transport of air and water vapour from the Swiss lowlands into the nearby western Alps, leading to orographic convection, is investigated using a range of independent observations. These observations are: Global Positioning System (GPS) integrated water vapour (IWV) data, the TROWARA microwave radiometer, MeteoSwiss ANETZ surface weather station data, the Payerne radiosonde, synoptic analyses for Switzerland and Europe, EUMETSAT and NOAA visible and infrared satellite images, MeteoSwiss operational precipitation radar, photographs and webcam images including time-lapse cloud animations. The intention was to show, using GPS IWV data, that significant differences in IWV may occur between the Swiss plain and nearby Alps during small single-cell Alpine thunderstorm events, and that these may be attributable to regional airflow convergence. Two particular case studies are presented for closer examination: 20 June 2005 and 13 June 2006. On both days, fine and warm weather was followed by isolated orographic convection over the Alps in the afternoon and evening, producing thunderstorms. The thunderstorms investigated were generally small, local, discrete and short-lived phenomena. They were selected for study because of almost stationary position over orography, rendering easy observation because they remained contained within a particular mountain region before dissipating. The results show that large transfers of air and water vapour occur from the Swiss plain to the mountains on such days, with up to a 50% increase in GPS IWV values at individual Alpine stations, coincident with strong airflow convergence in the same locality.

  10. Radiation toxicity in dogs

    International Nuclear Information System (INIS)

    Progress is reported on studies of the effects of continuous (22 hr/day), whole-body γ-irradiation in the pure-bred beagle dog. Dogs were exposed continuously until death at one of four different exposure rates ranging from 5 to 35 R/day. The study is still 2441 days (approximately 6.7 yr) of irradiation. The experiment has narrowed to the dogs receiving 5 R/day and the controls. A group of dogs receiving one of these relatively low daily exposure rates may exhibit remarkably varied responses, both in survival times in the γ field and in ultimate causes of death. The basis for these large differences in responses of individual dogs remains mostly unexplained, but is presumed to reside in their genetic composition. The composite result in the study, however, demonstrates an orderly, step-wise appearance of clinical end points resulting from radiation-induced damage to the blood-forming tissues. About one-half the dogs exposed continuously to 10 R/day develop bone marrow aplasia and die of anemia, while the other one-half develop bone marrow hyperplasias and die of malignancies, usually myelogenous leukemias. In dogs exposed at rates greater than 10 R/day, aplastic bone marrows predominate; while hyperplastic responses are the dominant cause of death at 5 R/day. Only among the most recent deaths of dogs exposed continuously to either 10 or 5 R/day, have there appeared terminal causes of death unrelated to hematopoietic injury. These causes (degenerative and/or inflammatory disease and cancers of tissue other than bone marrow) suggest that we are now beginning to define the combinations of exposure rate and time of exposure that allow expressions of damage by tissues outside the hematopoietic system.

    Objective To analyze the mid-term clinical and radiographic results obtained with the Bernese periacetabular osteotomy for the treatment of severe hip dysplasia. Methods From October 1997 to December 2002 20 hips of 18 patients were classified as having severe acetabular dysplasia (Severin classification Grade Ⅳb). Preoperatively, all patients had hip pain, and sufficient hip joint congruency on functional radiographs. All 20 hips underwent Bernese periacetabular osteotomy. Postoperatively, the hips were assessed radiographically on center edge angle (CE), acetabular roof obliquity and the progression of osteoarthritis. Clinical results and hip function were measured with the Harris hip score at an average of 6.2 years follow-up. Results Comparison of preoperative and follow-up radiographs demonstrated significant improvements in the lateral CE angle, the anterior CE angle, and roof obliquity. The average Harris hip score improved from 78.5 points preoperatively to 91.1 points at the time of the latest follow-up. Fourteen of 18 patients were satisfied with the result of the surgery, and 16 of 20 hips had a good or excellent clinical result. Undercorrection occurred in 5 hips. Conclusions The Bernese periacetabular osteotomy is an effective procedure for surgical correction of the severe dysplastic hip. This osteotomy can predictably obtain major reorientation of the acetabulum in all planes. The clinical results in the mid-term follow-up are encouraging.%目的 研究和分析使用伯尔尼髋臼周围截骨术治疗严重髋臼发育不良的中期临床和影像学结果.方法 1997年10月至2002年12月对18例(20髋)严重髋臼发育不良(Severin分级Ⅳb级)的患者接受了伯尔尼髋臼周围截骨术.患者手术时平均年龄21岁,平均随访时间6.2年.本组患者术前患髋均已出现疼痛,术前功能位片显示关节面吻合.术后影像学评价畸形的矫正范围,截骨处的愈合情况及关节炎的进展.临床结果和髋关

  6. Historical flood analysis of the Eistlenbach and Farnigraben torrents in the Hasli Valley (Bernese Alps) inferred from sedimentary records, historical maps and remote sensing

    Science.gov (United States)

    Monterrubio, Glòria; Schulte, Lothar

    2016-04-01

    Historical sources report that in 1624 the village of Hofstetten was ravaged by a major debris flow from the Eistlenbach torrent, and in 1797 another event erupted from the Lammbach, Schwanderbach and Eistlenbach torrents, demolishing 37 buildings (Eisbacher and Clague,1984). Years later there occurred more debris flows and floods in the area, which also affected buildings and farmlands in the valley. Every debris flow and flood leaves its footprint and shapes the morphology of the landscape causing aggradation in the distal area. The knowledge how landforms such as alluvial fans develop and which areas have been repeatedly affected by geomorphic dynamics is crucial for the assessment and management of hydrological hazards in mountain regions. The study aims to reconstruct historical floods and changes in the geomorphology of the distal areas of Eistlenbach and Farnigraben fans. First results show distinct flood layers which can be related to debris flow and flood events during the last 700 years. Peaks of Log (Zr/Ti) and Ca/Ti correlate with coarse-grained flood layers which can be compared with historical sources, whereas the organic-rich beds and soils indicate higher land surface stability and lower flood activity. In addition a spatial analysis is conducted to identify geomorphological dynamics and changes of the alluvial fan, particularly those which are related to the village of Hofstetten. Thus, survey of aerial photographs and satellite images as well as the interpolation of historical maps from 1797 to present, provide essential information of landform (e.g channels, levees and debris flow lobes) and land cover changes (vegetation, land-use, reforestation). For example, one of the most remarkable observations is the flow change of the Eistlenbach torrent. Previously to 1949 the channel path was straight to the watercourse of Fulbach in the valley bottom and was blocked by the rock drumlin Ballenberg in the south. But since then the channel started to

  7. Mitral stenosis in 15 dogs

    International Nuclear Information System (INIS)

    Mitral stenosis was diagnosed in 15 young to middle-aged dogs. There were 5 Newfoundlands and 4 bull terriers affected, suggesting a breed predisposition for this disorder. Clinical signs included cough, dyspnea, exercise intolerance, and syncope. Soft left apical diastolic murmurs were heard only in 4 dogs, whereas 8 dogs had systolic murmurs characteristic of mitral regurgitation. Left atrial enlargement was the most prominent radiographic feature. Left-sided congestive heart failure was detected by radiographs in 11 dogs within 1 year of diagnosis. Electrocardiographic abnormalities varied among dogs and included atrial and ventricular enlargement, as well as atrial and ventricular arrhythmias. Abnormalities on M-mode and two-dimensional echocardiograms included abnormal diastolic motion of the mitral valve characterized by decreased leaflet separation, valve doming, concordant motion of the parietal mitral valve leaflet, and a decreased E-to-F slope. Increased mitral valve inflow velocities and prolonged pressure half-times were detected by Doppler echocardiography. Cardiac catheterization, performed in 8 dogs, documented a diastolic pressure gradient between the left atrial, pulmonary capillary wedge, or pulmonary artery diastolic pressures and the left ventricular diastolic pressure. Necropsy showed mitral stenosis caused by thickened, fused mitral valve leaflets in 5 dogs and a supramitral ring in another dog. The outcome in affected dogs was poor; 9 of 15 dogs were euthanatized or died by 2 1/2 years of age

    Differential diagnoses for canine liver disease are commonly based on radiographic estimates of liver size, however little has been published on breed variations. Aims of this study were to describe normal radiographic liver size in Pekingese dogs and to compare normal measurements for this breed with other dog breeds and Pekingese dogs with liver disease. Liver measurements were compared for clinically normal Pekingese (n = 61), normal non-Pekingese brachycephalic (n = 45), normal nonbrachycephalic (n = 71), and Pekingese breed dogs with liver disease (n = 22). For each dog, body weight, liver length, T11 vertebral length, thoracic depth, and thoracic width were measured on right lateral and ventrodorsal abdominal radiographs. Liver volume was calculated using a formula and ratios of liver length/T11 vertebral length and liver volume/body weight ratio were determined. Normal Pekingese dogs had a significantly smaller liver volume/body weight ratio (16.73 ± 5.67, P brachycephalic breed dogs (19.54 ± 5.03) and normal nonbrachycephalic breed dogs (18.72 ± 6.52). The liver length/T11 vertebral length ratio in normal Pekingese (4.64 ± 0.65) was significantly smaller than normal non-Pekingese brachycephalic breed dogs (5.16 ± 0.74) and normal nonbrachycephalic breed dogs (5.40 ± 0.74). Ratios of liver volume/body weight and liver length/T11 vertebral length in normal Pekingese were significantly different from Pekingese with liver diseases (P dogs have a smaller normal radiographic liver size than other breeds. We recommend using 4.64× the length of the T11 vertebra as a radiographic criterion for normal liver length in Pekingese dogs. PMID:23094756

    This paper is a review of the history, development and efficacy of using dogs in wildlife studies and considers the use of dogs in the research and conservation of wild tigers (Panthera tigris Linnaeus, 1758). Using scat detection dogs, scent-matching dogs, law enforcement detection dogs and protection dogs are proven methods that can be effectively used on tigers. These methods all take advantage of the dog's extremely evolved sense of smell that allows them to detect animals or animal byproducts (often the focus of tiger studies). Dogs can be trained to communicate this information to their handlers. PMID:21392356

    2012-08-11

    Obesity is an important disease with a growing incidence. Because obesity is related to several other diseases, and decreases life span, it is important to identify the population at risk. Several risk factors for obesity have been described in the literature. A higher incidence of obesity in certain breeds is often suggested. The aim of this study was to determine whether obesity occurs more often in certain breeds. The second aim was to relate the increased prevalence of obesity in certain breeds to the official standards of that breed. To this end, we investigated 1379 dogs of 128 different breeds by determining their body condition score (BCS). Overall, 18.6% of the show dogs had a BCS >5, and 1.1% of the show dogs had a BCS>7. There were significant differences between breeds, which could be correlated to the breed standards. It warrants firm discussions with breeders and judges in order to come to different interpretations of the standards to prevent overweight conditions from being the standard of beauty. PMID:22882163

  2. Lead poisoning in dogs

    International Nuclear Information System (INIS)

    Lead poisoning was diagnosed and studied in 60 dogs. It was found that lead poisoning is a common disease of young dogs, especially in the summer and fall, and is related to their chewing and eating habits resulting in the ingestion of paint, linoleum, or other lead-containing materials. The signs were characterized by gastrointestinal dysfunction (colic, vomiting, and diarrhea) and nervous disorders (convulsions, hysteria, nervousness, behavioral changes). The blood findings, which the authors consider nearly pathognomonic, consisted of numerous stippled and immature (especially nucleated) erythrocytes in the absence of severe anemia. Protein and casts were frequently found in the urine. Radiography sometimes revealed lead-containing particles in the gastro-intestinal tract, and lead lines were occasionally detected in the metaphysis of long bones in immature dogs. Treatment with calcium ethylenediamine-tetraacetic acid resulted in rapid and often dramatic recoveries in nearly all instances. Removal of lead from the gastrointestinal tract and treatment to relieve pronounced central nervous disorders was sometimes necessary. 40 references, 6 figures, 7 tables

  3. Do Dog Behavioral Characteristics Predict the Quality of the Relationship between Dogs and Their Owners?

    2001-03-01

    A report is given on eight years of experience with the Bavarian legal regulation for the protection against dangerous dogs of 10.7.1992. The implementation of the regulation was a success. Since then only two cases of biting accidents are reported. In one case the dogs were euthanatized, in the other case they were taken away and given to other owners. The advantages of the regulation are seen in the increased responsibility of the dog owner who has to give proof of the peaceful character of his dog in form of an expert testimony. This lowers the administration costs and has revealed a preventive effect, the dog owners are looking more carefully after their animals to avoid any security problems. PMID:11314462

    Full Text Available This paper presents a review of a dog, with a retrobulbar chondrosarcoma, which was admitted for surgery for visible changes in his eye during inspection. Orbital neoplasia in dogs may be primary and secondary. Sixty percent of orbital neoplasia in dogs are primary, ninety percent of which are malignant. Retrobulbar neoplasms are rare and in their early stage represent a diagnostic challenge. Chondrosarcoma of the skull is a slow-progressing malignant disease which occurs locally, aggressive with invasion into the surrounding tissues. Dogs with chondrosarcoma of the skull have life expectancy between 210 and 580 days - in our case it was 180 days - after the first alterations on the eye of the dog occurred.

  10. Radiation toxicity in dogs

    International Nuclear Information System (INIS)

    Three related, but separate, studies are in progress. In the first, young adult beagles of both sexes are placed in the γ-ray field, to be kept there for duration of life at one of a number of daily exposure rates. In the second, young adult beagles are exposed in a similar fashion until they have accumulated predetermined amounts of total exposure ranging up to 4000 R, delivered at various daily exposure rates. They are then removed from the radiation field and kept for the rest of their lives to allow development of late effects attributable to radiation exposure. In the third study, pregnant beagles are irradiated, at one of four daily exposure rates, for all or part of their gestation periods, to produce an evaluation of the effects of continuous irradiation in the developing fetus. All of these studies are done by arranging dogs at various distances from a calibrated 60Co γ-ray source, where they are irradiated during 22 hours of each day. The remaining 2 hours are used for animal care, maintenance, and clinical evaluation of the dogs. The combined results demonstrate that the cellular and organ systems of the dog respond predictably, and in a differential manner, depending on exposure rate. Exposure rates in excess of 17 R/day destroy the blood-cell producing elements of bone marrow and cause death, therefore, within 1 to 2 months. Minimally sublethal exposure rates to bone marrow (5-17 R/day), however, produce a very high (50-75 percent) incidence of anemia or myeloid leukemia. Furthermore, at exposure rates of 5 R/day or below, bone marrow appears to function in an essentially normal fashion, and causes of death appear, from preliminary data, to be related to degenerative disease and malignancies of other tissues

    High genetic diversity of East Asian village dogs has recently been used to argue for an East Asian origin of the domestic dog. However, global village dog genetic diversity and the extent to which semiferal village dogs represent distinct, indigenous populations instead of admixtures of various dog breeds has not been quantified. Understanding these issues is critical to properly reconstructing the timing, number, and locations of dog domestication. To address these questions, we sampled 318 village dogs from 7 regions in Egypt, Uganda, and Namibia, measuring genetic diversity >680 bp of the mitochondrial D-loop, 300 SNPs, and 89 microsatellite markers. We also analyzed breed dogs, including putatively African breeds (Afghan hounds, Basenjis, Pharaoh hounds, Rhodesian ridgebacks, and Salukis), Puerto Rican street dogs, and mixed breed dogs from the United States. Village dogs from most African regions appear genetically distinct from non-native breed and mixed-breed dogs, although some individuals cluster genetically with Puerto Rican dogs or United States breed mixes instead of with neighboring village dogs. Thus, African village dogs are a mosaic of indigenous dogs descended from early migrants to Africa, and non-native, breed-admixed individuals. Among putatively African breeds, Pharaoh hounds, and Rhodesian ridgebacks clustered with non-native rather than indigenous African dogs, suggesting they have predominantly non-African origins. Surprisingly, we find similar mtDNA haplotype diversity in African and East Asian village dogs, potentially calling into question the hypothesis of an East Asian origin for dog domestication.

  13. Radiation toxicity in dogs

    International Nuclear Information System (INIS)

    The overall goal of this project is measurement of the late effects of low doses of ionizing radiation in a large, relatively long-lived animal, the dog, to aid in assessing hazards and understanding mechanisms of radiaton damage in man. Young adult beagles are given whole-body exposures to protracted irradiation (22 hours/day, 7 days/week) from 60Co gamma ray sources. They are exposed: (1) until they die; or (2) until they accumulate predetermined total doses of irradiation. The dogs are monitored regularly by clinical, hematological, and pathological examinations. End points determined are times to death (life shortening), causes of death, and characterization of all pathological processes. Monitoring of the hematopoietic system is emphasized because of the importance of myelogenous leukemia and related myeloproliferative disorders as shown by data in other experimental species and in man. Earlier exposures, given continuously until death or terminated at predetermined total ic fields associated with energy transmission. Proteins in human urine and selected tissues are examined by two-dimensional electrophoresis to detect disease and pollutant related changes. Assessment of human risk associated with nuclearing collective dose commitment will result in more attention being paid to potential releases of radionuclides at relatively short times after disposal

    2015-05-01

    Full Text Available Romanian Mioritic Shepherd Dog, was selected from a natural population breed in Carpathian Mountains. The aim of this paper was to estimate variance at 12 body measurements using 26 males from Romanian Mioritic Shepherd Dog breed. The animals were registered with the Romanian Mioritic Association Club from Romania. The statistical data showed that there is a large variance for body length and tail length, a middle variance for the croup width and thorax width and a small variance for height at withers, height at middle of back, height at croup, height at the base of the tail, depth of thorax, thoracic perimeter, elbow height and height of the hock. We recommend of breeders dogs from this breed to take account in genetic improvement programs, of values presented in this paper.

  15. Multiple enchondromatosis in the dog

    International Nuclear Information System (INIS)

    The clinical and radiological findings of three related Miniature Poodles with multiple enchondromatosis (Ollier's disease) are presented. Persisting, in part ossified growth plate cartilage foci were found bilaterally in the humerus, radius, ulna, femur, tibia and fibula of each dog and in one dog in some metacarpal and metatarsal bones. The ribs and many vertebral bodies were also affected. There was evidently no bone formation in the sternebrae. All three dogs first attracted attention at the ages of four to six months, with spontaneous bilateral femoral neck fractures. The mode of inheritance of the condition is not yet clear, but based on the known pedigree data a dominant effect appears unlikely

    A retrospective study of 91 dogs with pemphigus foliaceus was performed. Clinical signs of the disease included crusts (n=79), pustules (n=36), and alopecia (n=33). Lesions were most common on the trunk (n=53), inner pinnae (n=46), face (n=37), and foot pads (n=32). Cytological evaluation revealed acantholytic keratinocytes in 37 of 48 dogs. Results of combination treatment with prednisolone and azathioprine were comparable to results with prednisolone therapy alone. More than half of the dogs achieved remission with appropriate therapy, and another 25% significantly improved. PMID:16611930

    Full Text Available Mountain waves could be modified as the boundary layer varies between stable and convective. However case studies show mountain waves day and night, and above e.g. convective rolls with precipitation lines over mountains. VHF radar measurements of vertical wind (1990–2006 confirm a seasonal variation of mountain-wave amplitude, yet there is little diurnal variation of amplitude. Mountain-wave azimuth shows possible diurnal variation compared to wind rotation across the boundary layer.

  20. Ureteral diverticula in two dogs

    International Nuclear Information System (INIS)

    We describe ureteral diverticula in two dogs and briefly review the related literature. The diagnosis of this condition is radiographic and based on the excretory urographic observation of multiple ureteral outpouchings. Pathologically, ureteral transitional cell hyperplasia and mucinous metaplasia result in submucosal proliferation of the urothelium and the formation of crypts and small cysts. Ureteral diverticulosis in humans is associated with an increased risk of urothelial malignancies, such as transitional cell carcinoma of the urinary bladder. Clinically, both dogs were older, small breed neutered females. Both had a history of chronic urinary obstruction. One dog died during surgery to remove an adrenal mass, and the other was euthanized at the owner's request because of an inoperable bladder neoplasm. Histopathologic diagnosis of ureteral lesions confirmed the radiographic diagnosis of ureteral diverticula in both dogs

    We report an experimental investigation into whether domesticated dogs display contagious yawning. Fifteen dogs were shown video clips of (1) humans and (2) dogs displaying yawns and open-mouth expressions (not yawns) to investigate whether dogs showed contagious yawning to either of these social stimuli. Only one dog performed significantly more yawns during or shortly after viewing yawning videos than to the open-mouth videos, and most of these yawns occurred to the human videos. No dogs showed significantly more yawning to the open-mouth videos (human or dog). The percentage of dogs showing contagious yawning was less than chimpanzees and humans showing this behavior, and considerably less than a recently published report investigating this behavior in dogs (Joly-Mascheroni et al. in Biol Lett 4:446-448, 2008).

    The ''Yucca Mountain Site Description'' summarizes, in a single document, the current state of knowledge and understanding of the natural system at Yucca Mountain. It describes the geology; geochemistry; past, present, and projected future climate; regional hydrologic system; and flow and transport within the unsaturated and saturated zones at the site. In addition, it discusses factors affecting radionuclide transport, the effect of thermal loading on the natural system, and tectonic hazards. The ''Yucca Mountain Site Description'' is broad in nature. It summarizes investigations carried out as part of the Yucca Mountain Project since 1988, but it also includes work done at the site in earlier years, as well as studies performed by others. The document has been prepared under the Office of Civilian Radioactive Waste Management quality assurance program for the Yucca Mountain Project. Yucca Mountain is located in Nye County in southern Nevada. The site lies in the north-central part of the Basin and Range physiographic province, within the northernmost subprovince commonly referred to as the Great Basin. The basin and range physiography reflects the extensional tectonic regime that has affected the region during the middle and late Cenozoic Era. Yucca Mountain was initially selected for characterization, in part, because of its thick unsaturated zone, its arid to semiarid climate, and the existence of a rock type that would support excavation of stable openings. In 1987, the United States Congress directed that Yucca Mountain be the only site characterized to evaluate its suitability for development of a geologic repository for high-level radioactive waste and spent nuclear fuel.

    2008-04-17

    A cross-sectional telephone survey of randomly selected households examined the extent and types of problems associated with free-roaming dogs and cats in the Teramo province of Italy. The households were sampled randomly within each municipality; municipalities were combined into coastal, central hills and mountain regions for analysis. The survey was conducted in May and June of 2004 with a response rate of 74% (397/536). Ninety percent of respondents (N=356) believed that free-roaming dogs and cats were a problem. They were most commonly concerned about personal safety, followed by animal welfare, public health and environmental sanitation. Sixty-nine percent of respondents (274) actually saw free-roaming dogs or cats where they live. While dogs were most commonly seen, cats were seen in greater numbers. Overall, 10% (39/297) and 5% (21/397) of respondents cared for free-roaming cats and dogs, respectively. Two-thirds of the respondents (251/397) believed that animals were abandoned because the owners lost interest. About 2/3 of respondents (251/397) reported that the community government should have the responsibility for dealing with free-roaming dogs and cats. The respondents supported the idea of building more shelters and controlling the birth rate as control measures rather than euthanizing dogs and cats. The results suggest that free-roaming dogs and cats are a very common sight in this part of Italy with substantial concerns by the residents. However, concerns about the animals' welfare were clearly raised, supporting the laws that make it illegal to euthanize a healthy dog or cat in Italy. Using the information from this study, research on the underlying causes of abandonment of dogs and cats or failing to sterilize them should be undertaken to begin to address this problem. Further, national and regional funding must be provided to support existing laws which should help protect and eventually decrease the numbers of free-roaming and homeless dogs and

  12. Chemodectoma in dogs

    International Nuclear Information System (INIS)

    Tumors of the chemoreceptor organs are referred to as chemodectomas. Such tumors develop principally in the aortic and carotid bodies of animals. Aortic body tumors occur four times more frequently than do carotid body tumors. Brachycephalic breeds (e.g., boxers, Boston terriers, and English bulldogs) are over represented among reported cases of canine chemodectoma. Old male dogs are at greater risk of developing the condition. Tumors of the aortic body occur more often as single or multiple nodules in the pericardial sac near the base of the heart. Carotid body tumors arise near the bifurcation of the common carotid artery in the cranial cervical region. Clinical signs at presentation include signs of right-sided congestive heart failure (aortic body tumor) and the presence of a neck mass (carotid body tumor). In the absence of necropsy, definitive diagnosis is usually based on exploratory surgery and histopathology of surgically excised tissue. Currently, early surgical excision is the preferred treatment. Radiation therapy has been used in a limited number of cases. The prognosis for animals diagnosed with chemodectoma is guarded to fair

    2012-02-01

    There are currently about 80 different DNA tests available for mutations that are associated with inherited disease in the domestic dog, and as the tools available with which to dissect the canine genome become increasingly sophisticated, this number can be expected to rise dramatically over the next few years. With unrelenting media pressure focused firmly on the health of the purebred domestic dog, veterinarians and dog breeders are turning increasingly to DNA tests to ensure the health of their dogs. It is ultimately the responsibility of the scientists who identify disease-associated genetic variants to make sensible choices about which discoveries are appropriate to develop into commercially available DNA tests for the lay dog breeder, who needs to balance the need to improve the genetic health of their breed with the need to maintain genetic diversity. This review discusses some of the factors that should be considered along the route from mutation discovery to DNA test and some representative examples of DNA tests currently available.

This study was conducted to determine the prevalence of zoonotic and non-zoonotic gastrointestinal parasites in dogs in Calgary city parks, and assess if dog-walking behaviour, park management, history of veterinary care, and dog demographics were associated with parasitism in dogs Methods From June to September 2010, 645 questio...

  20. Intracranial lesions in dogs with hemangiosarcoma

    International Nuclear Information System (INIS)

    A retrospective analysis of 85 dogs with hemangiosarcoma (HSA) that underwent complete necropsy, including gross examination of the brain, was conducted. Grossly identifiable intracranial lesions were present in 17 dogs. Twelve of 85 dogs (14.2%) had brain metastases. Four of 85 dogs (4.7%) had hemorrhagic lesions and/or ischemic necrosis without identifiable tumor. One dog had a primary central nervous system tumor. Signs of intracranial disease were present in six of 85 dogs (7.1%) with HSA; four had brain metastases and two had nonneoplastic lesions. Metastases had a propensity for cerebrum and gray matter. Dogs with brain metastases had more widely disseminated disease than dogs without brain metastases (P less than 0.001). Dogs with pulmonary metastases were at greater risk for developing brain metastases than dogs without pulmonary metastases (odds ratio = 8.31). Although thoracic radiography accurately identified ten of 12 dogs (83%) with pulmonary metastases, too few cases were available to assess the applicability/accuracy of thoracic radiography in predicting the presence or absence of brain metastases in dogs with malignancy and signs of intracranial disease

  1. Permanent transvenous pacemaker implantation in forty dogs

    International Nuclear Information System (INIS)

    Permanent transvenous cardiac pacemakers were implanted in 40 dogs. Electrocardiographic diagnoses included persistent atrial standstill (3 dogs), sick sinus syndrome (8 dogs), and high-grade second-degree or third-degree atrioventricular (AV) block (29 dogs). Thirteen dogs were alive and well 4 to 42 months after pacemaker implantation (mean, 16.9 months). The mean and median survival times of the 26 dogs that died or were euthanatized during the study were 17.9 months and 13 months, respectively. Most of these dogs succumbed to problems unrelated to the arrhythmia and pacemaker implant. One dog was lost to follow-up. Complications associated with permanent transvenous pacemaker implantation included lead dislodgement, infection, hematoma formation, skeletal muscle stimulation, ventricular arrhythmia, migration of the pulse generator, and skin erosion. Lead dislodgement was the most common complication, occurring in 7 of 9 dogs paced using untined electrode leads and in 6 of 30 dogs paced using tined leads. Lead dislodgement did not occur in the only dog paced using an actively fixed endocardial lead. It was concluded that permanent transvenous cardiac pacing is a feasible, less traumatic alternative to epimyocardial pacing in dogs, but that successful use of this technique requires careful implantation technique and anticipation of the potential complications

    Sequential changes in pathology were examined for scabies-infested dogs to determine the effects of infestation with Sarcoptes scabiei var. canis. During 8 wk of infestation with S. scabiei, the progression of the disease was evaluated weekly by skin scrape, clinical examination, and blood analyses. At 8 wk, selected organs were microscopically examined for histopathology. All infested dogs developed an advanced level of scabies infestation by 8 wk. Of the 36 blood parameters evaluated, only values for erythrocyte sedimentation rate (ESR) deviated significantly from the normal ranges for dogs. However, infested dogs had significantly (P dogs. Red blood cell levels for infested dogs dropped significantly (P dogs compared to controls, some individual infested dogs exhibited eosinophilia at 4-8 wk of infestation. The ESRs for infested dogs were significantly (P dogs prior to infestation or control dogs. All parameters except neutrophils had returned to preinfestation levels by 2 wk after treatment for scabies. Neutrophil concentrations were no longer significantly different by 4 wk posttreatment. There were no significant differences in serum enzyme, biochemical and electrolyte concentrations between infested and control dogs.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7472858

    The Strawberry Mountain Wilderness extends 18 mi along the crest of the Strawberry Range and comprises about 53 sq mi in the Malheur National Forest, Grant County, Oregon. Systematic geologic mapping, geochemical sampling and detailed sampling of prospect workings was done. A demonstrated copper resource in small quartz veins averaging at most 0. 33 percent copper with traces of silver occurs in shear zones in gabbro. Two small areas with substantiated potential for chrome occur near the northern edge of the wilderness. There is little promise for the occurrence of additional mineral or energy resources in the Strawberry Mountain Wilderness.

  10. Inhaled plutonium oxide in dogs

    International Nuclear Information System (INIS)

    This project is concerned with long-term experiments to determine the lifespan dose-effect relationships of inhaled 239PuO2 and 238PuO2 in beagles. Beagle dogs given a single exposure to 239PuO2 or 238PuO2 aerosols are being observed for lifespan dose-effect relationships. The 239Pu body burden of the nine dogs that died of pulmonary-fibrosis-induced respiratory insufficiency during the first 3 yr after exposure was 1 to 12μCi. Nineteen of the dogs exposed to 238Pu haved died during the first 7-1/2 yr after exposure due to bone and/or lung tumors; their body burdens at death ranged from 0.7 to 10μCi. Chronic lymphopenia was the earliest observed effect after inhalation of 239PuO2 or 238PuO2

    Dog parks are very popular in urban areas, but there are no current studies attempting to correlate visits to dog parks and risk of colonization by enteric parasites. The purpose of this study was to determine whether dog park visitation is associated with an increased prevalence of enteric parasites or an increase in prevalence of gastrointestinal signs in dogs in northern Colorado. Feces from dogs owned by veterinary students or Veterinary Teaching Hospital staff members were submitted with a completed survey form detailing dog park attendance rates, fecal character scores, and other clinical information. Feces were examined microscopically for parasites after sugar centrifugation, for Giardia spp. cysts and Cryptosporidium spp. oocysts by a commercially available immunofluorescence assay (FA) and the FA positive samples were genotyped after PCR amplification. The Giardia assemblages were determined using the glutamate dehydrogenase (GDH) β-giardin and triose phosphate isomerase (TPI) genes and the Cryptosporidium species were determined using the heat shock protein-70 gene. A total of 129 fecal samples were assayed; 66 were from dog park attending dogs and 63 were from non-dog park-attending dogs. The overall parasite prevalence rate was 7.0% (9 of 129 samples). Dog park attending dogs were more likely to be positive for Giardia or Cryptosporidium than non-dog park-attending dogs (p=0.0279), but there was no association of gastrointestinal signs with dog park attendance or with fecal flotation or FA results. The five Giardia isolates were assemblage C and/or D and the one Cryptosporidium isolate was Ctenocephalides canis. PMID:21890275

    2001-06-01

    Almost every second trekker or climber develops two to three symptoms of the high altitude illness after a rapid ascent (> 300 m/day) to an altitude above 4000 m. We distinguish two forms of high altitude illness, a cerebral form called acute mountain sickness and a pulmonary form called high altitude pulmonary edema. Essentially, acute mountain sickness is self-limiting and benign. Its symptoms are mild to moderate headache, loss of appetite, nausea, dizziness and insomnia. Nausea rarely progresses to vomiting, but if it does, this may anticipate a progression of the disease into the severe form of acute mountain sickness, called high altitude cerebral edema. Symptoms and signs of high altitude cerebral edema are severe headache, which is not relieved by acetaminophen, loss of movement coordination, ataxia and mental deterioration ending in coma. The mechanisms leading to acute mountain sickness are not very well understood; the loss of cerebral autoregulation and a vasogenic type of cerebral edema are being discussed. High altitude pulmonary edema presents in roughly twenty percent of the cases with mild symptoms of acute mountain sickness or even without any symptoms at all. Symptoms associated with high altitude pulmonary edema are incapacitating fatigue, chest tightness, dyspnoe at the minimal effort that advances to dyspnoe at rest and orthopnoe, and a dry non-productive cough that progresses to cough with pink frothy sputum due to hemoptysis. The hallmark of high altitude pulmonary edema is an exaggerated hypoxic pulmonary vasoconstriction. Successful prophylaxis and treatment of high altitude pulmonary edema using nifedipine, a pulmonary vasodilator, indicates that pulmonary hypertension is crucial for the development of high altitude pulmonary edema. The primary treatment of high altitude illness consists in improving hypoxemia and acclimatization. For prophylaxis a slow ascent at a rate of 300 m/day is recommended, if symptoms persist, acetazolamide at a

    Our aim was to evaluate how human beliefs affect working dog outcomes in an applied environment. We asked whether beliefs of scent detection dog handlers affect team performance and evaluated relative importance of human versus dog influences on handlers' beliefs. Eighteen drug and/or explosive detection dog/handler teams each completed two sets of four brief search scenarios (conditions). Handlers were falsely told that two conditions contained a paper marking scent location (human influence). Two conditions contained decoy scents (food/toy) to encourage dog interest in a false location (dog influence). Conditions were (1) control; (2) paper marker; (3) decoy scent; and (4) paper marker at decoy scent. No conditions contained drug or explosive scent; any alerting response was incorrect. A repeated measures analysis of variance was used with search condition as the independent variable and number of alerts as the dependent variable. Additional nonparametric tests compared human and dog influence. There were 225 incorrect responses, with no differences in mean responses across conditions. Response patterns differed by condition. There were more correct (no alert responses) searches in conditions without markers. Within marked conditions, handlers reported that dogs alerted more at marked locations than other locations. Handlers' beliefs that scent was present potentiated handler identification of detection dog alerts. Human more than dog influences affected alert locations. This confirms that handler beliefs affect outcomes of scent detection dog deployments. PMID:21225441

    2008-01-15

    This article reported on the use of trained detector dogs to track down leaks in pipelines instead of using electronic methods. Detector Dog Services International has more than 20 years of experience in training dogs for police and security work around the world, including training dogs to pick up the scent of oil leaking from pipelines. Instead of using a chemical scent to help the dogs track in, the company trains its dogs to pick up on the scent of components in oil that make their way from a buried pipeline leak up to the surface. The compounds in the oil are used to train the dogs. The dog is trained to signal when the appropriate scent is picked up and is rewarded for finding the leak. A properly trained dog can cover a kilometre of pipeline in half an hour, and can typically cover 10 kilometres in a day's work. To date, the use of leak detection dogs in the oil industry has yet to be adopted on a regular basis. Although Detector Dog Services International has worked with Duke Energy near Fort St. John doing some leak detection work, the trend towards using costly high-tech equipment has continued.

    Efficacy of albendazole for treating giardiasis in dogs was assessed in 3 experiments. In experiment 1, Giardia cysts were cleared from feces of 5 of 7 dogs (as determined by the zinc-sulfate concentration technique) after the dogs received a single dose of albendazole (25 mg/kg of body weight, PO), whereas feces of 3 of 7 dogs became clear of cysts without treatment. In experiment 2, feces of 5 of 5 dogs became clear of cysts after albendazole treatment (25 mg/kg, PO, q 12 h for 4 doses); feces of 1 of 5 untreated control dogs became clear. In experiment 3, feces of 18 of 20 dogs became clear of cysts after albendazole (25 mg/kg, PO, q 12 h for 4 doses) was given; none of the 20 control dogs had feces clear of cysts. Signs of toxicosis were not observed in any dog. These results indicate that a single dose of albendazole (25 mg/kg, PO) is not effective for treating giardiasis in dogs. However, 4 doses of albendazole (25 mg/kg, PO, q 12 h) are highly effective and non-toxic for treatment of giardiasis in dogs. PMID:8323064

    Canine polyneuropathy is a neurological disorder characterized by a dysfunction of multiple peripheral nerves. The etiology of the disease is diverse; it may occur in cases of infectious, immune-mediated, or hereditary conditions or in association with endocrinopathy, neoplasm, or chemical intoxication. It is often difficult to determine the etiology through clinical symptoms. The aim of this study is to investigate pathological differences among three canine polyneuropathy cases with each presumably having a different etiology. Cases included a 13-month-old female border collie (Dog No.1), a 21-month-old male chihuahua (Dog No.2) and an 11-year-old male beagle (Dog No.3). Clinical examinations revealed hindlimb ataxia and sensory loss in Dog No.1, forelimb paralysis and vertebral pain in Dog No.2, and paddling-gait and hypothyroidism in Dog No.3. Histopathologically, axonal swelling and pale myelin were observed in Dog No.1. Giant axons mimicking giant axonal neuropathy were obvious in Dog No.2. Dog No.3 showed atrophic axons and severe interstitial edema. Distributions of peripheral nerve lesions coincided with respective clinical symptoms. According to their clinical and pathological features, Dogs No.1 and No.2 were suspected of hereditary polyneuropathy, while Dog No.3 seemed to have hypothyroidism-associated polyneuropathy. As each case demonstrated unique pathological features, different pathogeneses of peripheral nerve dysfunction were suggested. PMID:23123885

    In Fukushima, Japan, a prolonged refugee situation caused by a major nuclear incident after the earthquake of March 11, 2011 has led to the unintentional abandonment of many pets. We received stray or abandoned dogs from rescue centers in Fukushima Prefecture. During re-socialization training and health care, we accessed the behavioral characteristics and the urine cortisol level of each dog and compared them with those of other abandoned dogs not involved in this earthquake. The dogs from Fukushima showed significantly lower aggression toward unfamiliar people, trainability, and attachment to their caretakers; also, urine cortisol levels in the dogs from Fukushima were 5-10-fold higher than those in abandoned dogs from another area of Japan. These results suggested that the dogs from Fukushima suffered through an extremely stressful crisis. PMID:23061007

  3. Metabolism of methylphenidate in dog and rat

    International Nuclear Information System (INIS)

    The urinary metabolites of methylphenidate in the dog and rat were investigated. After oral administration of 14C-labeled methylphenidate, approximately 86% and 63% of the dose was recovered in the urine of the dog and rat, respectively. Less than 1% of the dose was excreted as unchanged drug. Metabolism involved oxidation, hydrolysis, and conjugation processes. The primary hydrolytic product was alpha-phenyl-2-piperidineacetic acid (24%, dog; 35-40%, rat). The primary metabolites of oxidation were methyl 6-oxo-alpha-phenyl-2-piperidineacetate (3%, dog; 1.5%, rat) and the glucuronide of alpha-(p-hydroxyphenyl)-2-piperidineacetic acid (10%, rat). The former also underwent extensive biotransformation, including: 1) hydrolysis to the lactam acid (27%, dog; 7-10%, rat) and subsequent carboxylic acid O-glucuronidation (15%, dog); or 2) hydroxylation at the 5-position (1%, dog; 2%, rat) and subsequent hydrolysis (4%, dog; 15-17%, rat); or 3) 5-O-glucuronidation (12%, dog). Additional minor metabolites from methyl-6-oxo-alpha-phenyl-2-piperidineacetate were the phenolic O-glucuronide of methyl alpha-(p-hydroxyphenyl)-6-oxo-2-piperidineacetate (1%, dog), and the 4-O-glucuronide of methyl 4-hydroxy-6-oxo-alpha-phenyl-2-piperidineacetate (1%, dog), and the taurine amide conjugate of alpha-(p-hydroxyphenyl)-6-oxo-2-piperidineacetic acid (1%, dog). Additional products from methylphenidate conjugation included methyl 1-carbamoyl-alpha-phenyl-2-piperidineacetate (1%, dog or rat) and its carboxylic acid hydrolysis product (1%, rat). The chirality of the major metabolites isolated from dog urine showed that metabolism was partially stereoselective in all investigated cases, except in the formation of alpha-phenyl-2-piperidineacetic acid

    2013-04-01

    Colonial burrowing herbivores can modify vegetation structure, create belowground refugia, and generate landscape heterogeneity, thereby affecting the distribution and abundance of associated species. Black-tailed prairie dogs (Cynomys ludovicianus) are such a species, and they may strongly affect the abundance and composition of grassland bird communities. We examined how prairie dog colonies in the North American Great Plains affect bird species and community composition. Areas occupied by prairie dogs, characterized by low percent cover of grass, high percent cover of bare soil, and low vegetation height and density, supported a breeding bird community that differed substantially from surrounding areas that lacked prairie dogs. Bird communities on colony sites had significantly greater densities of large-bodied carnivores (Burrowing Owls [Athene cunicularia], Mountain Plovers, [Charadrius montanus], and Killdeer [Charadrius vociferus]) and omnivores consisting of Horned Larks (Eremophila alpestris) and McCown's Longspurs (Rhynchophanes mccownii) than bird communities off colony sites. Bird communities off colony sites were dominated by small-bodied insectivorous sparrows (Ammodramus spp.) and omnivorous Lark Buntings (Calamospiza melanocorys), Vesper Sparrows (Pooecetes gramineus), and Lark Sparrows (Chondestes grammacus). Densities of 3 species of conservation concern and 1 game species were significantly higher on colony sites than off colony sites, and the strength of prairie dog effects was consistent across the northern Great Plains. Vegetation modification by prairie dogs sustains a diverse suite of bird species in these grasslands. Collectively, our findings and those from previous studies show that areas in the North American Great Plains with prairie dog colonies support higher densities of at least 9 vertebrate species than sites without colonies. Prairie dogs affect habitat for these species through multiple pathways, including creation of belowground

  8. Experimental infection of dogs with a Brazilian strain of Rickettsia rickettsii: clinical and laboratory findings

    2008-11-01

    Full Text Available The bacterium Rickettsia rickettsii is the etiological agent of an acute, severe disease called Rocky Mountain spotted fever in the United States or Brazilian spotted fever (BSF in Brazil. In addition to these two countries, the disease has also been reported to affect humans in Mexico, Costa Rica, Panama, Colombia and Argentina. Like humans, dogs are also susceptible to R. rickettsii infection. However, despite the wide distribution of R. rickettsii in the Western Hemisphere, reports of R. rickettsii-induced illness in dogs has been restricted to the United States. The present study evaluated the pathogenicity for dogs of a South American strain of R. rickettsii. Three groups of dogs were evaluated: group 1 (G1 was inoculated ip with R. rickettsii; group 2 (G2 was infested by R. rickettsii-infected ticks; and the control group (G3 was infested by uninfected ticks. During the study, no clinical abnormalities, Rickettsia DNA or R. rickettsii-reactive antibodies were detected in G3. In contrast, all G1 and G2 dogs developed signs of rickettsial infection, i.e., fever, lethargy, anorexia, ocular lesions, thrombocytopenia, anemia and detectable levels of Rickettsia DNA and R. rickettsii-reactive antibodies in their blood. Rickettsemia started 3-8 days after inoculation or tick infestation and lasted for 3-13 days. Our results indicate that a Brazilian strain of R. rickettsii is pathogenic for dogs, suggesting that canine clinical illness due to R. rickettsii has been unreported in Brazil and possibly in the other South American countries where BSF has been reported among humans.

    Full Text Available Abstract Background This study examines changes in socio-demographic, environmental and intrapersonal factors associated with dog acquisition in non-dog owners at baseline to 12-months follow-up and the effect of dog acquisition on minutes per week of recreational walking. Methods RESIDE study participants completed self-administered questionnaires (baseline and 12-months follow-up measuring physical activity, dog ownership, dog walking behavior as well as environmental, intrapersonal and socio-demographic factors. Analysis was restricted to 'Continuing non-owners' (i.e., non-owners at both baseline and follow-up; n = 681 and 'New dog owners' (i.e., non-owners who acquired a dog by follow-up; n = 92. Results Overall, 12% of baseline non-owners had acquired a dog at follow-up. Dog acquisition was associated with working and having children at home. Those who changed from single to couple marital status were also more likely to acquire a dog. The increase in minutes of walking for recreation within the neighborhood from baseline to follow-up was 48 minutes/week for new dog owners compared with 12 minutes/week for continuing non-owners (p p p > 0.05 after further adjustment for change in baseline to follow-up variables. Increase in intention to walk was the main factor contributing to attenuation of the effect of dog acquisition on recreational walking. Conclusion This study used a large representative sample of non-owners to examine the relationship between dog acquisition and recreational walking and provides evidence to suggest that dog acquisition leads to an increase in walking. The most likely mechanism through which dog acquisition facilitates increased physical activity is through behavioral intention via the dog's positive effect on owner's cognitive beliefs about walking, and through the provision of motivation and social support for walking. The results suggest that behavioral intention mediates the relationship between dog acquisition

    Anecdotally, an unusually hyperechoic pancreas can be found in seemingly healthy dogs on ultrasound examination and the prevalence and clinical significance of this finding is unknown. The objective of this study was to describe the prevalence of a hyperechoic and/or heterogenous pancreas in healthy dogs and correlate these findings to weight, age, and body condition score (BCS). An additional objective was to describe the prevalence of a hyperechoic and/or heterogenous pancreas in dogs with hyperadrenocorticism and compare this to the healthy dogs. Pancreata of 74 healthy dogs were evaluated prospectively and pancreatic echogenicity and echotexture were graded. Each dog's age, BCS, and weight were recorded. Dogs were screened for health by physical examination, serum chemistry panel, urine specific gravity, and a canine pancreatic lipase immunoreactivity assay. Pancreatic images for 92 dogs having hyperadrenocorticism were also reviewed and pancreatic echogenicity and echotexture were recorded. The prevalence of pancreatic hyperechogenicity in normal dogs was 7% (5 of 74) and heterogeneity was 40% (30 of 74). No correlation existed between pancreatic echogenicity and weight, age, or BCS (P > 0.1 for all sets). A statistically significant increase in the proportion of dogs having a hyperechoic pancreas was found in the hyperadrenocorticism sample of dogs (40%, 37 of 92, P < 0.0001). The underlying cause of pancreatic variability in the few healthy dogs and in dogs with hyperadrenocorticism is unknown and the varying appearance of the pancreas in these samples confounds interpretation of diseases such as chronic pancreatitis.

  11. Supraspinatus and biceps brachii tendinopathy in dogs

    International Nuclear Information System (INIS)

    Calcifying tendinopathy was seen on radiographic views of the scapulohumeral joint in 12 of 183 (7 per cent) dogs reviewed retrospectively. Calcifying tendinopathy was identified only in large breed dogs, five being labradors. All the affected dogs, except one, were presented for unilateral thoracic limb lameness, which was typically of a chronic and intermittent pattern. Pain on manipulation of the scapulohumeral joint in the lame leg was present in eight of 12 dogs (67 per cent). Calcification of the supraspinatus tendon was seen in eight dogs and calcification of the biceps brachii tendon was seen in the other four dogs. Radiographic changes indicative of biceps brachii tendon avulsion were found in conjunction with calcification of the contralateral biceps brachii tendon in two dogs. Filling defects, indicative of bicipital tenosynovitis, were also seen in positive contrast arthrograms of two dogs with biceps brachii calcification. Of the eight dogs for which radiographic views of both scapulohumeral joints were available, six dogs had bilateral radiographic signs of calcifying tendinopathy. Overall, radiographic signs of calcifying tendinopathy were seen in 18 scapulohumeral joints, but lameness was apparent in only nine limbs, suggesting the lesion may at times be asymptomatic. Further prospective investigation of calcifying tendinopathy is needed to determine why lameness does not always appear to be associated with the presence of the lesion

    Full Text Available The aim of our study was to find association between the personality of owners and the personality of their dogs, assessed by their owners. Furthermore, we were interested in finding differences between dogs of different breeds. The sample included 661 owners (556 women and 105 men and an equal number of their dogs (332 females and 329 males. The participants filled in the Big Five Inventory and slightly adopted the Big Five Inventory for dogs. The results indicated statistically significant correlations between almost all owner's personality dimensions and personality dimensions of their dogs. Besides the influence of owners and their personalities on the dog's personality, a possible cause of these associations could be their misevaluation as they want their dogs to have some equal characteristics as they have. Analysis of the data also revealed significant differences in dimensions between breeds in three of four dogs' personalities. Results were partly in accordance with hypothesized differences which were based upon official descriptions of temperament of specific breeds. Despite the fact that the research confirms that owners can judge dog's personality with satisfactory levels of accuracy, it is necessary to account all limitations of measuring dogs' personality in interpreting the results.

    Estimates of the prevalence of intestinal infection of dogs with Giardia spp. in the United States vary widely. Risk factors for infection in a large sample of dogs over an extended period of time have not been well characterized. A national, electronic database of medical records was used to estimate the prevalence and identify risk factors for Giardia spp. infection among dogs visiting Banfield Pet Hospital™ located in 43 states in the United States. The overall prevalence of Giardia spp. Infection was 0.44% (95% CI: 0.43-0.45%) in approximately 2.5 million owned dogs who had a fecal flotation test performed from January 2003 to December 2009. A steady decrease in annual prevalence was observed, from a high of 0.61% in 2003 to 0.27% in 2009. Seasonal increases in prevalence were noted during the winter and summer months. Giardia spp. prevalence was highest in the Mountain region, especially Colorado (2.63%; 95% CI: 2.53-2.73%), and in puppies ≤0.5 year of age (0.63%; 95% CI: 0.61-0.64%). It was lowest for dogs of mixed breeding compared with pure breeds. Infection risk was 25-30% greater in sexually intact dogs compared to spayed and neutered dogs. PMID:23337331

  16. Pulmonary mineralization in four dogs with Cushing's syndrome

    International Nuclear Information System (INIS)

    The clinical and imaging features of four dogs with Cushing's syndrome and pulmonary mineralization are reviewed. Three dogs presented with a primary complaint of respiratory distress/dyspnea. Three dogs had pituitary dependent Cushing's syndrome, while the remaining one dog had iatrogenic Cushing's syndrome. Each dog had clinical features typical for Cushing's syndrome. Two of the dogs were euthanized due to progressive hypoxemia. In each dog, the serum calcium, phosphorous, blood urea nitrogen and creatinine were normal. A generalized increase in unstructured interstitial pulmonary opacity with diffuse mineralization was noted on thoracic radiographs of all dogs. In one dog, an ill-defined nodular interstitial pattern of mineralization was present. Delayed bone phase scintigraphy using 99mTechnetium methylene diphosphonate documented generalized pulmonary uptake in two dogs. 99mTechnetium labeled microaggregated albumin lung perfusion scans were normal in these two dogs. 99mTc-MDP scintigraphy can provide useful information in diagnosing pulmonary mineralization in Cushingoid dogs

    The metabolism, dosimetry and biological effects of inhaled 91YCl3 in Beagle dogs are being studied. Forty-two dogs with initial 90Y body burdens from 14 to 1300 μCi per kilogram body weight and 12 control dogs are being maintained for lifetime observation. Four additional dogs with a mean initial body burden of 180 μCi 91Y per kilogram body weight were placed in a sacrifice study. Forty-four of the exposed dogs and all 12 of the control dogs have died. Dogs with the highest initial body burdens died with bone marrow damage and pancytopenia. Three dogs died with nasal cavity carcinomas, three dogs died with pulmonary carcinomas and one dog died with hepatic hemangiosarcoma; these cancers all appeared to be related to radiation injury. Control dogs died of miscellaneous neoplastic and chronic diseases. Observations are continuing on the two surviving exposed dogs

    2016-08-01

    Venturing into the mountains, doctors have accompanied expeditions to provide routine care to the teams, undertake research and occasionally take on a rescue role. The role of doctors practicing mountain medicine is evolving. Public health issues involving concepts of health and safety have become necessary with the coming of commercial and youth expeditions. Increasingly individuals with a disability or a medical diagnosis choose to ascend to high altitudes. Doctors become involved in assessment of risk and providing advice for such individuals. The field of mountain medicine is perhaps unique in that acceptance of risk is part of the ethos of climbing and adventure. The pursuit of mountaineering goals may represent the ultimate conquest of a disability. Knowledge of mountain environment is essential in facilitating mountain ascents for those who choose to undertake them, in spite of a disability or medical condition. PMID:27234206

    Five Border Collie dogs with ceroid-lipofuscinosis developed progressive neurological disease between 18 and 22 months of age. These dogs had behavioural abnormalities, gait and visual deficits and became progressively demented. All dogs examined had common ancestors. Light microscopic examination of tissues demonstrated extensive accumulation of granular, sudan black-staining autofluorescent material in the cytoplasm of neurones, retinal ganglion cells and some visceral cells. At ultrastructural examination inclusions of variable morphology were observed. PMID:3376765

    A monitoring programme aimed at the diagnosis of subcutaneous dirofilariasis and heartworm disease in working (police and military) dogs in Slovakia has been performed during the period of September 2007 to February 2008. In co-operation with the Ministry of the Interior and the Ministry of Defence, in total, 710 dogs (591 police dogs and 119 military dogs) were investigated for the presence of microfilariae in blood. All police and military dogs in active service held on the territory of Slovakia were included. Microfilariae were detected in 118 (20.0%) police dogs and 10 (8.4%) military dogs. The most infected individuals originated from southern parts of Slovakia (Trnava region 53.6% and Nitra region 39.6%); the prevalence was low in northern regions (Zilina 3.1% and Presov 6.6%). In several districts of southern Slovakia, the prevalence of subcutaneous dirofilariasis in working dogs exceeded 40%. In all infected animals, the autochthonous origin of the disease was confirmed; however, due to the frequent movement of working dogs, it was not possible to identify the exact locality of infection. At present, a dog living in Nemsová village in Trencín district (north-western part of the country) is regarded as the northernmost localized autochthonous case of subcutaneous dirofilariasis in Slovakia. In three dogs, co-infection of Dirofilaria repens and Dirofilaria immitis was detected. High prevalence rates in working dogs and the zoonotic characteristic of the disease represent an undoubtedly important veterinary and medical problem that requires the urgent introduction of prophylactic and control measures.

As part of this program, we developed a robot with the capability to learn and recognize the appearance of target objects, conduct an area search amid distractor objects and obstacles, and relocate the target object in the same way that Mine dogs and Sentry dogs are used within military contexts for exploration and threat detection. Neya teamed with the Robotics Institute at Carnegie Mellon University to develop vision-based solutions for probabilistic target learning and recognition. In addition, we used a Mission Planning and Management System (MPMS) to orchestrate complex search and retrieval tasks using a general set of modular autonomous services relating to robot mobility, perception and grasping.

    1993-07-15

    The diagnosis of food allergy was confirmed in 51 dogs while the responsiveness to a 60-day home-cooked restricted dietary trial (elimination-diet trial) was evaluated. The primary clinical sign of allergy detected and evaluated in all dogs was persistent and nonseasonally pruritic skin disease. The duration of time between starting the elimination-diet trial and remission of clinical signs was recorded. Dogs were then reexposed to diets that had been fed before testing, and the duration of time before pruritus recurred was recorded. The elapsed time during which dogs were being fed an elimination diet before remission of clinical signs was 1 to 3 weeks in 13 dogs, 4 to 6 weeks in 25 dogs, 7 to 8 weeks in 10 dogs, and 9 to 10 weeks in 3 dogs. Findings indicated that the recommendation of a 3-week elimination-diet trial for diagnosis of food allergy was adequate for only 25% of the dogs. It is recommended that test diets be fed for at least 10 weeks before a food allergy is ruled out. PMID:8407485

    The role of dogs in the transmission of Coxiella burnetii to humans is uncertain, and extensive seroprevalence studies of dogs have not been previously conducted in Australia. This study determined C. burnetii exposure in four diverse canine subpopulations by adapting, verifying and comparing an indirect immunofluoresence assay (IFA) and an enzyme-linked immunosorbent assay (ELISA) used to detect anti-C. burnetii antibodies in humans. Canine serum samples (n = 1223) were tested with IFA from four subpopulations [breeding establishments; household pets; free-roaming dogs in Aboriginal communities; shelter dogs]. The proportions of seropositive dogs were as follows: breeding (7/309, 2.3%), household pets (10/328, 3%), Aboriginal communities (21/321, 6.5%) and shelters (5/265, 1.9%). Dogs from Aboriginal communities were 2.8 times (CI 1.5-5.1; P roaming dogs associated with Aboriginal communities. As C. burnetii recrudesces during pregnancy and birth products contain the highest concentration of organism, individuals assisting at the time of parturition, those handling pups shortly after birth as well as those residing in the vicinity of whelping dogs are potentially at risk of developing Q fever. However, the identification of active antigen shed in excreta from seropositive dogs is required in order to accurately define and quantify the public health risk. PMID:26729351

A total of 209 local, cross breed and breed dogs sera from Kodya Bogor, Kabupaten Bogor, Sukabumi, and Jakarta, had been tested using Haemagglutination Inhibition Test (HI with pig red blood cells. A total of 64 breed and cross breed dogs from Sukabumi and Kodya Bogor, were used as a sentinel dogs to study the epidemiology of Canine parvovirus (CPV infection and its immunological responses caused by vaccination. The results indicated that 78% (95 breed and cross bred dogs and 59% (51 local dogs had antibody to CPV. Sentinel dogs results indicated that dogs had been vaccinated showed antibody response with the varied titre dependant upon prevaccination titre. Low prevaccinated titre gave better response than protective level titre. From 19 puppies observed, Maternal antibodi were still detected until 5 weeks old puppies. First vaccination given at less than 3 months old, should be boosted after 3 months old puppied. Antibodi titre produced by natural infection will keep untill 2 years. These data concluded that the dog condition and time of vaccination will affect the optimum antibody response.

    Carl Hallencreutz

    1979-01-01

    Full Text Available In this paper the author focuses on the religious function of symbols in the encounter and interaction of Christianity and other religions. Some observations on the religious function of the symbol of the Holy Mountain in different African contexts are presented. These contexts are a traditional Kikuyu religion, b a Christian hymn from Northern Tanzania, and c the New Year's Fiest of the independent Nazaretha Church among Zulu in South Africa. The examples of how the symbol of the holy mountain is used in different religious contexts in Africa are, of course, too limited to provide a basis for far-reaching generalizations on how symbols function religiously in the encounter of Christianity and other religions. However, this kind of analysis can be applied also when studying other encounters of religions inside and outside Africa. The symbol functions both as a carrier of a new religious message and as an indigenous means to appropriate this message locally and give it adequate form in different milieus. The symbols, which most likely have the religious functions are those which are of a general nature; light, way, living water, and which some are tempted to speak of as archetypes. Yet the comparison between the Chagga-hymn to the holy mountain and Shembe's interpretation of the blessing of the New Year's Fiest on Inhlangakozi indicates, that in the encounter of Christianity and other religions it is not only the symbols as such which produce the local appropriation of the new religious message and give it adequate localized form. Not even in the encounter of Christianity and other religions the symbols function religiously without human beings as actors in the historical process.

Thoracic radiographic changes were variable and were not diagnostic. Bronchoscopic evidence of mild to severe bronchitis was present in 12 dogs. Abnormal numbers of eosinophils were found in bronchoalveolar lavage samples and, or, bronchial washings in all 14 cases, but no significant bacteria were recovered. Respiratory compliance was measured in five dogs and was abnormal in three. Faecal examination for helminth parasites was carried out in four cases, a large ascarid burden being identified in one. Intradermal skin testing was carried out in three dogs but was negative in all cases. Complete remission of signs was achieved with prednisolone in 12 cases with six dogs requiring continuous or repeated treatment. Three dogs died as a direct consequence of progression of the disease

    Accurate measurement of small intestinal digestibility is important in dogs because it allows the formulation of pet foods that provide optimal nutrition at minimal cost. Digestibility measured by comparing nutrient intake to fecal excretion in intact animals does not distinguish small intestinal digestion from large intestinal bacterial fermentation. Ileal cannulation allows small intestinal digestion to be measured alone by comparing nutrient intake with ileal excretion of chyme. Nevertheless, ileal cannulation and its associated complications are not well documented in dogs. We describe the implantation of a simple T-cannula in the ileum of nine dogs for an average duration of 26 weeks. Established cannulas were well tolerated, and one dog retained the cannula for 14 months. Nevertheless, ileal effluent proved extremely caustic, and the incidence of complications in the immediate postoperative period was high. Only one dog had an unremarkable postoperative course. Complications included abscessation and cannula extrusion, followed by severe excoriation and ulceration of the skin. This excoriation could be prevented only by immediate surgical closure of the fistula. Chronic ileal cannulation is therefore a viable technique in dogs, but careful monitoring of the cannula site is essential. Dogs should be subjected to this procedure only if adequate veterinary and nursing care is available. It is preferable to maintain a colony of long-term cannulated dogs rather than to implant cannulas as needed. PMID:8699825

    Full Text Available The present study was carried out during the month of January 2014 when a total of 148 dogs with history of various diseases were presented to the Campus Veterinary Hospital, Teaching Veterinary Clinical Complex, College of Veterinary Science, Rajendranagar, Hyderabad, India. Out of 148 dogs that were presented to the hospital, 48 dogs had the clinical signs of loss of hair, itching, and reduced food intake. The dogs were restless and continuously rubbed their bodies against the walls in the houses, and scratching with their legs. Clinical examination of the dogs revealed presence of alopecia, pruritus, and the formation of small crusts. All 48 dogs were treated with ivermectin by subcutaneous injection dosed at 0.02 mL/kg body weight at a weekly interval for 2 to 3 weeks. All dogs were bathed with cypermethrin shampoo weekly once for 2-3 weeks. In the present study, it was observed that ivermectin/cypermethrin combination therapy was effective for the management of tick infestation in dogs.

    BackgroundIt has been shown that the prevalence of both clinical attachment loss (CAL) >1 mm and pocket probing depth (PPD) >4 mm is relatively high even in younger dogs, but also that only a minority of the dogs have such clinical signs of periodontal disease (PD) in more than a few teeth. Hence......, a minority of dogs carry the major PD burden. These epidemiological features suggest that screening for PD in larger groups of dogs, allowing for rapid assessment of treatment planning, or for the selection of dogs with or without PD prior to be included in experimental trials, should be possible...... laboratory Beagle dogs was to construct a fast, simple and accurate screening tool, which is highly sensitive for the identification of dogs with PD.ResultsExamination of the maxillary P4, P3, P2, I1 and C would, in this population, result in the identification of 85.5% of all dogs and 96% of all teeth...

It discusses (a biogeographical trends, (b the general properties of biodiversity, (c environmental factors and the regulation of biodiversity with respect to ecosystem function, (d the results of research on mountain freshwater ecosystems, and (e climate change and air pollution dominated environmental interactions.- The section on biogeographical trends highlights the importance of altitude and latitude on biodiversity. The implications of the existence of different scales over the different levels of biodiversity and across organism groups are emphasised as an inherent complex property of biodiversity. The discussion on ecosystem function and the regulation of biodiversity covers the role of environmental factors, productivity, perturbation, species migration and dispersal, and species interactions in the maintenance of biodiversity. Regional and long-term temporal patterns are also discussed. A section on the relatively overlooked topic of mountain freshwater ecosystems is presented before the final topic on the implications of recent climate change and air pollution for mountain biodiversity.

  13. Spinal epidural empyema in two dogs

    International Nuclear Information System (INIS)

    Extensive, diffuse, epidural spinal cord compression was visualized myelographically in two dogs presented for rapid development of nonambulatory tetraparesis and paraplegia, respectively. Purulent fluid containing bacterial organisms was aspirated percutaneously under fluoroscopic guidance from the epidural space of each dog. One dog responded poorly to aggressive medical therapy, which included installation of an epidural lavage and drainage system. Both dogs were euthanized due to the severe nature of their disorder and the poor prognosis. Spinal epidural empyema (i.e., abscess) is a rare condition in humans and has not been reported previously in the veterinary literature. Spinal epidural empyema should be considered as a differential diagnosis in dogs presenting with painful myelopathies, especially when accompanied by fever

    Serum ferritin concentration increases in dogs in association with various diseases. In this study, we measured serum ferritin levels in dogs with splenic masses, using a sandwich ELISA assay. Eleven dogs with hemangiosarcoma (HSA), six with hematoma, 1 with hemangioma and 3 with lymphoma were enrolled. All dogs with HSA had serum ferritin concentrations above the normal limit (1,357 ng/ml, mean + 2× standard deviation of normal). Increased serum ferritin concentrations have also been observed in few cases of hematoma, hemangioma and lymphoma. Therefore, hyperferritinemia is not specific for splenic HSA, but may have clinical usefulness as a sensitive test for the disease. Further evaluation of serum ferritin concentrations in dogs with splenic HSA is needed. PMID:23803459

    Kin recognition requires the ability to discriminate between one's own genetic relatives and non-relatives. There are two mechanisms that aid in kin discrimination: phenotype matching and familiarity. Dogs may be a good model for assessing these mechanisms as dogs are a promiscuous social species with a keen sense of smell. Domestic dogs of both sexes were presented with two scents (close kin, distant-kin) and preference was assessed through three measures (latency to approach, number of visits, time spent). Experiment 1 explored the possibility of phenotype matching as subjects had no contact with sires, whose scent was presented alongside a control male's scent. Experiment 2 explored recognition of siblings raised with the subjects and then separated at seven weeks of age. Whereas female dogs in this experiment did not show a statistically significant preference, male dogs showed a preference for distant-kin when presented with sire and female sibling samples.

    Because of dogs' prolonged evolution with humans, many of the canine cognitive skills are thought to represent a selection of traits that make dogs particularly sensitive to human cues. But how does the dog mind actually work? To develop a methodology to answer this question, we trained two dogs to remain motionless for the duration required to collect quality fMRI images by using positive reinforcement without sedation or physical restraints. The task was designed to determine which brain circuits differentially respond to human hand signals denoting the presence or absence of a food reward. Head motion within trials was less than 1 mm. Consistent with prior reinforcement learning literature, we observed caudate activation in both dogs in response to the hand signal denoting reward versus no-reward. PMID:22606363

    The parasites which occurred most frequently in 175 owned or stray dogs in Sabah were Ancylostoma spp. present in 68% of the animals. Dirofilaria immitis occurred in 70% of the adult dogs but neither D. immitis nor Spirocerca lupi were present in puppies under four months of age. The latter attained a prevalence of 30% in the adults. In contrast Toxocara canis occurred in 81% of the puppies but infrequently in older dogs. Dipylidium caninum was moderately prevalent (15 to 25%) in dogs of all ages. Ticks were the most common arthropod parasite being present on 26% of the dogs and were mainly Rhipicephalus sanguineus. Demodectic and sarcoptic mange were confirmed and fleas and lice were also recovered. PMID:6730003

    Full Text Available The aim of the study was to describe the clinicopathological findings in dogs naturally infected with Babesia. During the period of February 2011-February 2012 twenty-nine cases of Babesia Canis were diagnosed in the clinic of Small Animal at the Veterinary Faculty of Tirana. The animal was considered infected when pear shaped babesia was observed inside infected erythrocytes in Wright-Giemsa stained blood smears. The animal stay for one week in our clinic and during this period we evaluated the canine babesiosis cases by means of clinical history, physical examination, hematological and biochemical tests. Based in the clinical sing of babesia the animal was divided in two groups with uncomplicated and complicate babesia. The duration of clinical signs ranged from 1 to 5 days prior to the arrival at the clinic and all the animals were positive with B. c. canis infections. The main clinical signs were dehydration and anemia in (79%, apathy (74%, anorexia or decrease appetite (70% and fever (68%. The anemia was present in the dogs and classified severe (13% as mild (45%, and moderate (52% of all the cases. In conclusion, the main clinicopathological findings were a mild to moderate hemolytic anemia and mild to severe thrombocytopenia.

  20. Geology at Yucca Mountain

    International Nuclear Information System (INIS)

    Both advocates and critics disagree on the significance and interpretation of critical geological features which bear on the safety and suitability of Yucca Mountain as a site for the construction of a high-level radioactive waste repository. Critics believe that there is sufficient geological evidence to rule the site unsuitable for further investigation. Some advocates claim that there is insufficient data and that investigations are incomplete, while others claim that the site is free of major obstacles. We have expanded our efforts to include both the critical evaluations of existing geological and geochemical data and the collection of field data and samples for the purpose of preparing scientific papers for submittal to journals. Summaries of the critical reviews are presented in this paper

    Written responses to a questionnaire by 255 officers who used canines in police work were assessed. Almost all officers frequently played with, talked to, petted, and brushed their dogs and believed the dogs benefitted their health and well-being. Officers whose dogs slept indoors, often in the same bedroom, generally said they loved their dogs and they described their dogs as calm rather than active, as indicated by a multiple correspondence analysis. These 96 officers more than the 154 officers whose dogs slept outdoors or in kennels also planned to remain in canine work. Although departments often assumed responsibility for purchasing the dogs, the more experienced officers usually were involved in the final selection of dogs (logistic regression: p dogs, 106 officers with a specific role in selecting their dogs planned to stay in canine work, as shown by a multiple correspondence analysis. They believed the dogs had saved their lives (p dogs, and also played with them for 6.5 hr. per week, assuring a regular pattern of exercise for the officers. Virtually all officers valued canine service and believed the dogs enhanced the department's effectiveness.

    Modern genetic samples are commonly used to trace dog origins, which entails untested assumptions that village dogs reflect indigenous ancestry or that breed origins can be reliably traced to particular regions. We used high-resolution Y chromosome markers (SNP and STR) and mitochondrial DNA to analyze 495 village dogs/dingoes from the Middle East and Southeast Asia, along with 138 dogs from >35 modern breeds to 1) assess genetic divergence between Middle Eastern and Southeast Asian village dogs and their phylogenetic affinities to Australian dingoes and gray wolves (Canis lupus) and 2) compare the genetic affinities of modern breeds to regional indigenous village dog populations. The Y chromosome markers indicated that village dogs in the two regions corresponded to reciprocally monophyletic clades, reflecting several to many thousand years divergence, predating the Neolithic ages, and indicating long-indigenous roots to those regions. As expected, breeds of the Middle East and East Asia clustered within the respective regional village dog clade. Australian dingoes also clustered in the Southeast Asian clade. However, the European and American breeds clustered almost entirely within the Southeast Asian clade, even sharing many haplotypes, suggesting a substantial and recent influence of East Asian dogs in the creation of European breeds. Comparison to 818 published breed dog Y STR haplotypes confirmed this conclusion and indicated that some African breeds reflect another distinct patrilineal origin. The lower-resolution mtDNA marker consistently supported Y-chromosome results. Both marker types confirmed previous findings of higher genetic diversity in dogs from Southeast Asia than the Middle East. Our findings demonstrate the importance of village dogs as windows into the past and provide a reference against which ancient DNA can be used to further elucidate origins and spread of the domestic dog.

  15. Arthrography of the dog's shoulder

    International Nuclear Information System (INIS)

    Different volumes with varying concentrations of meglumine-sodium diatrizoate were injected to study positive contrast shoulder arthrograms in six experimental dogs weighing 23-37 kg. The best delineation of the articular cartilage was obtained following injection of 1.5 ml of a 25% solution (185 mg iodine/joint). To visualize the bicipital tendon sheet and the different pouches of the shoulder joint, 6 ml of a 25% solution (750 mg iodine/joint) should be used. If no definite lesions are previewed, 6 ml of a 19% solution (550 mg iodine/joint) offers an acceptable compromise since with this volume and concentration no pooling of contrast medium overlapping the caudal area of the humeral head was seen. Radiographs should be obtained within 5 minutes after injection of the contrast medium. After that period the delineation of the joint structures is vaguening by absorption of the contrast medium. Repeated contrast examination with meglumine-sodium diatrizoate should be avoided. After four procedures at weekly intervals, the necropsy performed on two dogs showed inflammatory changes of the synovial membrane

    Quantum weak measurements with states both pre- and post-selected offer a window into a hitherto neglected sector of quantum mechanics. A class of such systems involves time dependent evolution with transitions possible. In this paper we explore two very simple systems in this class. The first is a toy model representing the decay of an excited atom. The second is the tunneling of a particle through a barrier. The post-selection criteria are chosen as follows: at the final time, the atom remains in its initial excited state for the first example and the particle remains behind the barrier for the second. We then ask what weak values are predicted in the physical environment of the atom (to which no net energy has been transferred) and in the region beyond the barrier (to which the particle has not tunneled). Thus, just as the dog that didn't bark in Arthur Conan Doyle's story Silver Blaze gave Sherlock Holmes meaningful information about the dog's non-canine environment, here we probe whether the particle that has not decayed or has not tunneled can provide measurable information about physical changes in the environment. Previous work suggests that very large weak values might arise in these regions for long durations between pre- and post-selection times. Our calculations reveal some distinct differences between the two model systems.

    1991-01-15

    Thirteen food-allergic dogs were studied to evaluate the efficacy of feeding a commercially available egg and rice diet, intradermal skin testing, and serologic testing by ELISA for diagnosing and/or characterizing food hypersensitivity. Feeding of a home-cooked whole lamb meat and rice diet for 3 weeks, followed by challenge with each dog's regular diet, served as the standard for diagnosing food hypersensitivity. Each dog underwent provocative testing with 6 individual ingredients to determine as many of its dietary allergens as possible. Prior to skin testing and serologic testing by ELISA, most dogs had been recently exposed to the offending diet and subsequently manifested clinical signs of allergy. All dogs that tolerated the aforementioned commercial diet were exposed to it for at least 7 weeks; 84.6% of food-hypersensitive dogs ate the commercial diet with impunity. Of the 2 reactors to the commercial diet, only 1 became pruritic in response to provocation testing with chicken eggs. Low sensitivity and high specificity were found for skin testing and the ELISA, indicating a lack of true- and false-positive reactions. Neither the positive nor negative predictive values adequately predicted positive and negative reactions, respectively, for either test. On the basis of these results, the commercial diet, skin testing, and anti-IgE ELISA cannot replace an owner-prepared food elimination diet for food hypersensitivity testing in dogs. PMID:2004984

    Full Text Available Giardiosis is one of the most frequent parasites of dogs and cats. Since several years, the treatment is based on the use of metronidazole. A coproscopic study in four dog kennels was conducted to demonstrate, at a significant level, the efficacy of oxfendazole (Dolthène®, Merial. At the posology of 11.3 mg/kg each day during three days (D1, D2 and D3, no dogs eliminated Giardia cysts and all dogs are clinically cured. The importance of hygienic measures is underlined. In kennels 1 and 2 where hygienic conditions were poor, dogs reexcreted cysts again after treatment. In kennels where the boxes were disinfected, no dogs, treated with 22.6 or 11.3 mg/kg, reexcreted Giardia cysts.

  2. Extinction of Harrington's mountain goat

    International Nuclear Information System (INIS)

    Keratinous horn sheaths of the extinct Harrington's mountain goat, Oreamnos harringtoni, were recovered at or near the surface of dry caves of the Grand Canyon, Arizona. Twenty-three separate specimens from two caves were dated nondestructively by the tandem accelerator mass spectrometer (TAMS). Both the TAMS and the conventional dates indicate that Harrington's mountain goat occupied the Grand Canyon for at least 19,000 years prior to becoming extinct by 11,160 +/- 125 radiocarbon years before present. The youngest average radiocarbon dates on Shasta ground sloths, Nothrotheriops shastensis, from the region are not significantly younger than those on extinct mountain goats. Rather than sequential extinction with Harrington's mountain goat disappearing from the Grand Canyon before the ground sloths, as one might predict in view of evidence of climatic warming at the time, the losses were concurrent. Both extinctions coincide with the regional arrival of Clovis hunters

    Two dogs were seen at the University Veterinary Teaching Hospital, Nairobi, Kenya, both having histories of dyspnoea, progressively enlarging abdomens, anasarca, ascites, pleural and pericardial effusion, and pulmonary oedema. One of the dogs had a mild neutrophilic leucocytosis, elevated levels of alkaline phosphatase, alanine aminotransferase, lactate dehydrogenase and proteinuria. Histopathological examination of the myocardium revealed some damage to myocytes and a mononuclear cellular infiltration involving the myocardium, liver and kidneys. The two dogs had a fondness for avocado fruits and, as the presenting syndrome is identical to that seen in goats, sheep and horses poisoned by avocados, a comparison is made and the probable manifestation of this poisoning presented.

    The most common disease process involving the larynx is laryngeal paralysis, which occurs much more frequently in dogs than in cats. Diagnosis of laryngeal paralysis requires close attention to anesthetic plane and coordination of respiratory effort with laryngeal motion. Surgical arytenoid lateralization improves respiration and quality of life in dogs with laryngeal paralysis; however, aspiration pneumonia is a recognized complication, and generalized neuropathy can progress. Laryngeal collapse can result from any cause of chronic upper airway obstruction, but is most often associated with unaddressed brachycephalic airway syndrome. Laryngeal neoplasia, while generally uncommon, occurs more frequently in cats than in dogs. PMID:24268331

    Cat scratch disease (CSD), caused by Bartonella henselae, is a zoonosis and characterized by self-limited lymphadenopathy. It is transmitted commonly by scratch or bite from cats or kitten. We report an unusual case of CSD caused by a domestic dog scratch that we believe is the first report in Taiwan. A 23-year-old healthy woman developed cervical lymphadenopathy, mild fever, headache, and malaise 3 days after dog scratch. Her symptoms improved after azithromycin treatment. Serology proved B. henselae infection. The owners of a domestic dog might be at risk of "cat" scratch disease. PMID:17493900

    Understanding the demography of domestic dogs is essential to plan the dog population management and rabies control program. In this study, we estimated the owned and stray dog population and the proportion of owned dogs that are free-roaming in Bhutan. For this, a cross-sectional household surveys were conducted in six districts (both urban and rural areas) and two border towns in southern Bhutan. The population estimation was done by extrapolation of the mean number of dogs per household and dogs per person, whilst mark-resight survey was conducted to estimate the proportion of owned dogs that were free-roaming. A total of 1,301 (rural:585; urban:716) respondents (one per household) were interviewed of which 173 households (24.4%) in urban areas owned 237 dogs whilst 238 households (40.8%) in rural areas owned 353 dogs. The mean number of dogs per dog owning household was estimated to be 1.44 (urban:1.37 dogs; rural:1.48 dogs) and dogs per household was estimated to be 0.45 (urban:0.33; rural:0.60). The dog: human ratio was 1:16.30 (0.06 dogs per person) in urban areas and 1:8.43 (0.12 dogs per person) in rural areas. The total owned dog population based on the mean number of dogs per household and dogs per person were estimated to be 65,312 and 71,245 in the country, respectively. The male: female ratio of the owned dog was 1.31:1 in urban areas and 2.05:1 in rural areas. Majority of the dogs were local non-descript breeds in both urban (60.8%) and rural (78%) areas, and the most common source was acquisition from friends or family (44.7%). The stray dog population in Bhutan was estimated to be 48,379 (urban:22,772; rural:25,607). Of the total estimated owned dog population in the two border towns, the proportion that were found free-roaming was estimated to be 31%. The different dog population estimation methods were compared and discussed in this paper. This study generated baseline data on the demographic patterns of the owned and stray dogs in Bhutan which

    As with most liver diseases, the symptoms of hepatitis in dogs are nearly always aspecific: the dogs eat less, are apathetic, sometimes have polyuria/polydipsia, and sometimes have diarrhoea. Hepatoencephalopathy and ascites only occur with these symptoms in very advanced stages of chronic hepatitis. Only a part of the dogs have jaundice. Because of these aspecific symptoms, the diagnosis hepatitis is often not taken into consideration, even though the presence of a liver disease can be easily detected by measuring plasma concentrations of alkaline phosphatase and bile acids, one or both of which are elevated. The diagnosis is confirmed by histological examination of a liver biopsy sample. The most common forms of hepatitis are non-specific reactive hepatitis, acute hepatitis, and chronic hepatitis. Non-specific reactive hepatitis is a reaction against endotoxin as a result of sepsis or an increased gastrointestinal absorption. Treatment is directed to the primary process. Leptospirosis also causes non-specific reactive hepatitis, but then renal insufficiency is the most prominent feature. The diagnosis is made not on the basis of a liver biopsy but on the basis of increased IgM titres against Leptospira. Immediate treatment with antibiotics and infusions at the first signs (jaundice and uraemia) can save the animal's life. Acute hepatitis can develop as a result of infection, toxins, or liver hypoxia. There is no specific treatment, but adequate recovery often occurs with supportive treatment. Corticosteroids are contraindicated. Chronic hepatitis, which can lead to cirrhosis, is the most common form of hepatitis. It is an autoimmune inflammatory reaction that is usually caused by a virus infection but sometimes by poisoning (intoxication). Long treatment with prednisolone or azathioprine is usually successful, but early recognition of the disease increases the likelihood of success. Nowadays, chronic hepatitis due to hepatic copper accumulation in Beddlington

As founding chair of the IGU Commission on High-Altitude Geoecology (1968, Troll laid the foundations for inter-disciplinary and international mountain research. The paper traces the evolution of the Commission and its close links with the UNESCO Man and Biosphere Programme (1972- and the United Nations University’s mountain Project (1978-. This facilitated the formation of a major force for inclusion of a mountain chapter in AGENDA 21 during the 1992 Rio de Janeiro Herat Summit (UNCED and the related designation by the United Nations of 2002 as the International Year of Mountains.

    Full Text Available An eight year old female dog was referred with anorexia, nervousness and emaciation. At the point of time, severe lifelessness was the only symptom. Then euthanasia was done according to the owner’s decision. As a result of postmortem examination, thin white matters were found on the gastric mucosa of the greater curvature and there were no other significant gross findings. Tissue specimens were collected from the gastric wall, esophagus, gall bladder, aorta, heart, kidneys, liver, mesenteric lymph node, lungs, urinary bladder and spleen and processed for histopathology. Microscopically, the masses of stomach were consisted of well-differentiated osteoid tissues, the compact bone-osteocytes and the matured lamellated bone with Haversian system. It was diagnosed as osteoma of the stomach. Other organs were free on such histological findings.

    The metabolism, dosimetry, and biological effects of inhaled 91YCl3 in Beagle dogs are being studied. Forty-two dogs with initial 91Y body burdens from 14 to 1300 μCi/kg body weight and 12 control dogs were observed during their life spans. Four additional dogs with a mean initial body burden of 180 μCi 91Y/kg body weight were placed in a sacrifice study. All 46 of the exposed dogs and all 12 of the control dogs have died. Dogs with the highest initial body burdens died with bone marrow damage and pancytopenia. Three dogs died with nasal cavity carcinomas, three died with pulmonary carcinomas, and one died with hepatic hemangiosarcoma. These cancers all appeared to be related to radiation injury.

    Unfortunately, the overpopulation of dogs is still a problem in the majority of countries and even though surgical methods of sterilization, the most traditional and commonly used technique, have been intensively performed, the impact on the dog population is negligible. The neutering of companion animals as ovariohysterectomy (spaying) or orchidectomy (castration) has its limitations because of the cost, the need of a surgical environment and the risk of surgical and/or anaesthetical complications (ACCD 2009). In fact, surgical castration has been banished in some northern European countries and has limited acceptance in other countries. In a survey performed in Sao Paulo, Brazil, 56.5% of the owners of adopted shelter dogs were against the surgical procedure for different reasons (Soto et al. 2005). Currently, the options for contraception, defined as suppression of fertility are based on hormonal treatment. The treatments can be divided into analogues of gonadotropin releasing hormone (GnRH), progestins and androgens. Other possibilities of contraception are via the immunological system with vaccinations against GnRH, the luteinizing hormone (LH) receptor and the zona pellucida proteins. Finally, there is also the intra-epididymal or intratesticular injection of sclerosing substances in dogs. Mechanical devices to disrupt fertility are not used anymore due to the side effects. Suppression of fertility in adult dogs will be reviewed in order of use and possible impact on the dog population. PMID:24947862

    Failures in the establishment of chromosomal, gonadal and phenotypic sex can cause intersexuality in dogs. Thus, diagnosis of chimaerism, mosaicism, sex reversal syndrome, and male or female pseudohermaphroditism in intersex individuals has to be based on the inspection of the chromosomes, gonads and the phenotypic appearance of the reproductive organs. In a study over two years, seven dogs of different breeds suspected to be intersexes were cytogenetically investigated. A sry-negative XX-sex reversal syndrome was diagnosed in a Jack Russel Terrier. In a mixbred dog a persistent Mullerian duct syndrome (PMDS) was found and a Border Terrier Dog showed an XX/XY chromosomal chimaerism. In further four dogs of different breeds, a female constitution of sex chromosomes was seen. As a sign of intersexuality each of these dog showed an enlarged clitoris. A differentiation between XX-sex reversal syndrome and female pseudohermaphroditism was not possible because there was no information on the internal genital tract and gonads available.

    This study reports the pharmacokinetics of amantadine in greyhound dogs after oral administration. Five healthy greyhound dogs were used. A single oral dose of 100 mg amantadine hydrochloride (mean dose 2.8 mg/kg as amantadine hydrochloride) was administered to nonfasted subjects. Blood samples were collected at predetermined time points from 0 to 24 h after administration, and plasma concentrations of amantadine were measured by liquid chromatography with triple quadrupole mass spectrometry. Noncompartmental pharmacokinetic analyses were performed. Amantadine was well tolerated in all dogs with no adverse effects observed. The mean (range) amantadine CMAX was 275 ng/mL (225-351 ng/mL) at 2.6 h (1-4 h) with a terminal half-life of 4.96 h (4.11-6.59 h). The results of this study can be used to design dosages to assess multidose pharmacokinetics and dosages designed to achieve targeted concentrations in order to assess the clinical effects of amantadine in a variety of conditions including chronic pain. Further studies should also assess the pharmacokinetics of amantadine in other dog breeds or using population pharmacokinetics studies including multiple dog breeds to assess potential breed-specific differences in the pharmacokinetics of amantadine in dogs.

    Efficacy of fenbendazole at 2 dosages for treating naturally acquired giardiasis in dogs was assessed. Giardia cysts were not detected in the feces of 6 of 6 group-1 dogs (as determined by use of the zinc sulfate concentration technique) after fenbendazole treatment (50 mg/kg of body weight, PO, q 24 h, for 3 doses). Cysts were not detected in the feces of 6 of 6 group-2 dogs after fenbendazole treatment (50 mg/kg of body weight, PO, q 8 h, for 3 days). However, cysts were not detected in the feces of only 1 of 6 group-3 (nontreated control) dogs. Signs of toxicosis were not observed in any dog. These results indicate that the current label dosage (for the treatment of Toxocara canis, Toxascaris leonina, Ancylostoma caninum, Uncinaria stenocephala, Trichuris vulpis, and Taenia pisiformis, but not Giardia spp) of fenbendazole (50 mg/kg, PO, q 24 h, for 3 doses) is also effective for treating giardiasis in dogs.

    In specific pathogen-free dogs, clinical signs of experimental canine parvovirus infection were mild, inconsistent and transient. Clinical signs were more pronounced in conventionally-raised dogs, but the severe disease reported in field cases was not reproduced in either group. A pronounced plasma viremia occurred on the 2nd to 4th day post-infection (d.p.i.) in dogs challenged oronasally. Antibody was detectable on the 5th d.p.i. Marked pyrexia was rare, but a significant temperature rise usually coincided with the appearance of antibody and the cessation of viremia. Significant lymphopenia, but not leukopenia, occurred on the 3rd to 7th d.p.i. Virus could be readily isolated from fecal matter on the 3rd to 8th d.p.i.; a few dogs continued to shed virus for up to 12 days. In dogs challenged parenterally, the onset of elevated temperatures, viral shed and antibody production occurred 24-48 hours sooner. Convalescent dogs were no longer contagious for susceptible contact animals 25 days or longer after challenge, although infectious virus persisted in feces for more than 6 months at room temperature. Active giardiasis seemed to exacerbate the clinical syndrome, although treatment with corticosteroids or anti-thymocyte serum did not. PMID:6211333

  7. Toad poisoning in three dogs: case reports

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Toad poisoning is frequent in dogs, but has been infrequently addressed in published case reports and review articles. Dogs can be poisoned when they bite a toad or otherwise ingest the venom. The venom effects manifest soon after the accident, since the toxin is rapidly absorbed by the mucous membrane of the digestive system. Hospital records of three dogs, diagnosed with toad poisoning, were retrospectively reviewed from January 2005 to July 2007. Poisoned dogs may present only local irritation or systemic signs in the gastrointestinal, cardiac and neurological systems. All three cases presented herein had clinical signs of gastrointestinal alterations including vomiting, sialorrhea and diarrhea. Two dogs developed abnormal cardiac rhythm and two exhibited neurological signs. A poisoned animal requires emergency care and symptomatic therapy with intense monitoring of its clinical parameters. Although there have been reports on the low mortality of dogs poisoned by toads, one animal died even after appropriate therapy. The severity of clinical signs and the risk of death must be considered by the veterinarian.

    Developing efficacious oral rabies vaccines is an important step to increase immunization coverage for stray dogs, which are not accessible for parenteral vaccination. Our previous studies have demonstrated that recombinant rabies virus (RABV) expressing cytokines/chemokines induces robust protective immune responses after oral immunization in mice by recruiting and activating dendritic cells (DCs) and B cells. To develop an effective oral rabies vaccine for dogs, a recombinant attenuated RABV expressing dog GM-CSF, designated as LBNSE-dGM-CSF was constructed and used for oral vaccination in a dog model. Significantly more DCs or B cells were activated in the peripheral blood of dogs vaccinated orally with LBNSE-dGM-CSF than those vaccinated with the parent virus LBNSE, particularly at 3 days post immunization (dpi). As a result, significantly higher levels of virus neutralizing antibodies (VNAs) were detected in dogs immunized with LBNSE-dGM-CSF than with the parent virus. All the immunized dogs were protected against a lethal challenge with 4500 MICLD50 of wild-type RABV SXTYD01. LBNSE-dGM-CSF was found to replicate mainly in the tonsils after oral vaccination as detected by nested RT-PCR and immunohistochemistry. Taken together, our results indicate that LBNSE-dGM-CSF could be a promising oral rabies vaccine candidate for dogs. PMID:26436700

  12. Contact with domestic dogs increases pathogen exposure in endangered African wild dogs (Lycaon pictus.

    Directory of Open Access Journals (Sweden)

    Rosie Woodroffe

    Full Text Available BACKGROUND: Infectious diseases have contributed to the decline and local extinction of several wildlife species, including African wild dogs (Lycaon pictus. Mitigating such disease threats is challenging, partly because uncertainty about disease dynamics makes it difficult to identify the best management approaches. Serious impacts on susceptible populations most frequently occur when generalist pathogens are maintained within populations of abundant (often domestic "reservoir" hosts, and spill over into less abundant host species. If this is the case, disease control directed at the reservoir host might be most appropriate. However, pathogen transmission within threatened host populations may also be important, and may not be controllable by managing another host species. METHODOLOGY/PRINCIPAL FINDINGS: We investigated interspecific and intraspecific transmission routes, by comparing African wild dogs' exposure to six canine pathogens with behavioural measures of their opportunities for contact with domestic dogs and with other wild dogs. Domestic dog contact was associated with exposure to canine parvovirus, Ehrlichia canis, Neospora caninum and perhaps rabies virus, but not with exposure to canine distemper virus or canine coronavirus. Contact with other wild dogs appeared not to increase the risk of exposure to any of the pathogens. CONCLUSIONS/SIGNIFICANCE: These findings, combined with other data, suggest that management directed at domestic dogs might help to protect wild dog populations from rabies virus, but not from canine distemper virus. However, further analyses are needed to determine the management approaches--including no intervention--which are most appropriate for each pathogen.

  13. The cerebrovascular structure and brain tissue volume: a comparative study between beagle dogs and mongrel dogs

    International Nuclear Information System (INIS)

    Objective: To compare the differences of cerebrovascular structure and brain tissue volume between beagle and mongrel dogs by using angiography and MR scanning. Methods: A total of 40 dogs, including 20 beagle dogs (beagle group) and 20 mongrel dogs (mongrel group), were enrolled in this study. Under general anesthesia, all dogs were examined with cerebral angiography and MR scanning. The cerebrovascular structure was evaluated with angiography via selective catheterization of aortic arch, bilateral external cerebral arteries (ECA), maxillary arteries, internal cerebral arteries (ICA) and vertebral arteries separately. The diameters of the ICA, middle cerebral artery (MCA), rostral cerebral artery (RCA), the anastomosis channel ICA and ECA, and basilar artery (BA) were measured at the similar point of each dog. Meanwhile the volumes of the brain tissue were calculated in coronal T2 view of MR scanning. The statistical analysis was performed among the weight of dogs, the diameter of arteries and the volume of brain tissue. The differences in the diameters and brain tissue volume were compared between the two groups. Results: No obvious variations in the cerebrovascular structure and brain tissue volume were found in these dogs. One mongrel dog was excluded from this study because of the severe stenosis of ICA. The mean weight of 20 beagle dogs and 19 mongrel dogs was (12.81±1.29) kg and (12.85±1.12) kg, respectively. The diameters of the ICA, MCA, RCA, the anastomosis channel between ICA and ECA and BA in beagle group were (1.26±0.07) mm, (0.90±0.05) mm, (0.58±0.07) mm, (0.55±0.07) mm and (0.95±0.06) mm, respectively. These parameters in mongrel group were (1.27±0.07) mm, (0.92±0.05) mm, (0.59±0.06) mm, (0.67±0.07) mm and (0.94±0.05) mm, respectively. The volume of brain in two groups was (76232.33±5018.51) mm3 and (71863.96±4626.87) mm3, respectively. There were no obvious correlation among the body weight, the cerebrovascular diameters and brain

  14. Timber Mountain Precipitation Monitoring Station

    International Nuclear Information System (INIS)

    A precipitation monitoring station was placed on the west flank of Timber Mountain during the year 2010. It is located in an isolated highland area near the western border of the Nevada National Security Site (NNSS), south of Pahute Mesa. The cost of the equipment, permitting, and installation was provided by the Environmental Monitoring Systems Initiative (EMSI) project. Data collection, analysis, and maintenance of the station during fiscal year 2011 was funded by the U.S. Department of Energy, National Nuclear Security Administration, Nevada Site Office Environmental Restoration, Soils Activity. The station is located near the western headwaters of Forty Mile Wash on the Nevada Test and Training Range (NTTR). Overland flows from precipitation events that occur in the Timber Mountain high elevation area cross several of the contaminated Soils project CAU (Corrective Action Unit) sites located in the Forty Mile Wash watershed. Rain-on-snow events in the early winter and spring around Timber Mountain have contributed to several significant flow events in Forty Mile Wash. The data from the new precipitation gauge at Timber Mountain will provide important information for determining runoff response to precipitation events in this area of the NNSS. Timber Mountain is also a groundwater recharge area, and estimation of recharge from precipitation was important for the EMSI project in determining groundwater flowpaths and designing effective groundwater monitoring for Yucca Mountain. Recharge estimation additionally provides benefit to the Underground Test Area Sub-project analysis of groundwater flow direction and velocity from nuclear test areas on Pahute Mesa. Additionally, this site provides data that has been used during wild fire events and provided a singular monitoring location of the extreme precipitation events during December 2010 (see data section for more details). This letter report provides a summary of the site location, equipment, and data collected in

    A cross-sectional study was conducted to determine the seroprevalence of Toxoplasma gondii agglutinins and to investigate the relationship between various risk factors and occurrence of toxoplasmosis in dogs in Trinidad. Of a total 250 dogs, comprising domestic, hunting and stray dogs, 80 (32.0%) were positive for T. gondii agglutinins at a titre of > or =1:32 using a latex agglutination test. Stray dogs (60.5%) had statistically significantly higher (P2-3 years age group compared with other age groups. Dogs that consumed home-cooked foods had a seroprevalence of 32.9% compared with those fed commercial dog foods (17.2%) and dogs fed both home-cooked and commercial foods (21.0%). However, the difference was not statistically significant (P>0.05; chi(2)). The rather high prevalence of toxoplasmosis in stray dogs is a good indication of the extent of the infection in the environment. PMID:12719132

    A 7-year-old, male, castrated, Labrador Retriever with a history of pancreatitis and inflammatory bowel disease presented for vomiting and anorexia. Serum biochemistry findings were indicative of cholestasis, hepatocellular insult, and decreased hepatic function. Ultrasound examination showed sediment and gas within the gallbladder, and a diagnosis of emphysematous cholecystitis was made. Emergency gallbladder resection was performed. Cytologic examination of bile fluid collected at surgery showed a mixed population of bacteria (bactibilia) together with fungal organisms consistent with Cyniclomyces guttulatus (previously known as Saccharomycopsis guttulatus). Similar fungal organisms were seen on a fecal smear. Bacteria cultured were normal gastrointestinal flora, supporting ascending infection; the fungal organisms were interpreted as incidental. Histopathology of the gallbladder indicated active (suppurative) and chronic (lymphocytic) cholecystitis and sections of liver tissue had evidence of chronic liver disease. A positive liver culture indicated concurrent bacterial hepatitis or cholangiohepatitis. Despite supportive care, the dog continued to decline and was euthanized 30 days later. Necropsy results confirmed end stage liver disease, but an initiating cause was not found. This case highlights the role of bactibilia in the development of acute cholecystitis and the unique cytologic appearance of C guttulatus as an incidental finding in bile fluid. PMID:17123257

  14. Toxicity of inhaled 91YCl3 in Beagle dogs. XII

    International Nuclear Information System (INIS)

    Studies on the metabolism, dosimetry and effects of inhaled 91YCl3 in Beagle dogs are being continued to provide information that will aid in assessing the biological consequences of nuclear accidents in which 91Y or other radionuclides that produce a similar radiation dose pattern may be released. Forty-two dogs with 91Y initial body burdens from 64 to 1300 μCi/kg body weight was placed in four groups with mean lung burdens of 310, 180, 75 and 40 μCi/kg body weight. These dogs and 12 control dogs are being maintained for lifetime observation. An additional group of four dogs with a mean initial 91Y body burden of 180 μCi/kg body weight was placed in a sacrifice study. Twenty-six of the exposed dogs and four of the control dogs have died. Eleven dogs within the highest activity level groups died or were euthanized at 12 to 33 days after inhalation of 91Y with changes related to severe bone marrow damage and associated pancytopenia. Two dogs died approximately one year after 91Y inhalation with convulsive seizures that were presumed to be unrelated to the 91Y exposure. Nine 91Y-exposed dogs died or were euthanized due to neoplasms 2012 to 4115 days after exposure. Three dogs had nasal squamous cell carcinomas, one had a bronchioloalveolar carcinoma, one a mast cell sarcoma, one a mammary adenocarcinoma, one a malignant lymphoma, one a melanosarcoma in the mouth and one heart base tumor. Two dogs died of renal failure 2663 and 4086 days after exposure. One dog died with autoimmune hemolytic anemia 3888 days after exposure and one died with congestive heart failure 4042 days after inhalation exposure. One control dog died of empyema, another control dog died with a mammary adenocarcinoma, one died with congestive heart failure and one with malabsorption syndrome.

  17. Rabies risk in raccoon dogs and foxes.

    Science.gov (United States)

    Singer, A; Kauhala, K; Holmala, K; Smith, G C

    2008-01-01

    Raccoon dogs are seen as a new host for fox rabies in Europe. Disease spread in a community of species can change the epidemiology of the disease and calls for new disease control strategies. This study assesses the risk of a rabies outbreak, introduced to a community of foxes and raccoon dogs in Southern Finland, as an example of the reintroduction of rabies into rabies-free areas. Epidemiology is simulated with a two-species model, based on approaches for rabies in foxes and parameterised from recently published data on raccoon dog and fox ecology in Northeast Europe. The risk of the establishment of rabies was investigated. The effectiveness of vaccination control was estimated. Results show that rabies may not spread in a single species, when population densities are low, as in Finland. However, persistent epidemics are very likely in the species' community. The threshold density for a system of combined species decreases non-linearly, compared to the thresholds of each of the species. A behavioural factor that influences rabies epidemiology is raccoon dog hibernation, which may alter with climate change. Thus, the new host, the raccoon dog, has to be considered in defining new emergency control strategies for rabies free states in Europe. PMID:18634482

  18. Pharmacokinetics of azithromycin in rats and dogs.

    Science.gov (United States)

    Shepard, R M; Falkner, F C

    1990-01-01

    After intravenous or oral administration to rats and dogs, azithromycin was rapidly distributed into the tissues, where concentrations frequently exceeded those in serum by 100-fold or more within 24 h of a single dose. Tissue concentrations were proportional to the dose following single administrations of 10 to 40 mg/kg in rats and dogs. Tissue concentrations were higher after multiple dosing and became greater as the dose was increased from 10 to 40 mg/kg. Elimination half-lives were similar in most tissues and were about 40 h in rats after seven doses of 20 mg/kg and about 90 h in dogs after five doses of 30 mg/kg. Serum concentrations declined in a multi-exponential manner, reflecting initial rapid distribution into tissues and then slow return to serum from tissues. Azithromycin had good oral bioavailability in rats and dogs (46% and 97%, respectively). Rapid uptake of azithromycin by tissues from serum and slow redistribution from tissues to serum are apparently factors governing the pharmacokinetics of azithromycin in rats and dogs. Serum concentrations do not reflect the availability of azithromycin in tissues. PMID:2154438

  5. [The nature of the dog--a contribution to the keeping and breeding of so-called fighting dogs].

    Science.gov (United States)

    Loeffler, K; Eichelberg, H

    1991-06-01

    The behavioural repertoire of dogs derives from that of the wolf. But there are distinct race-specific differences which go back to the man's breeding influence in the course of domestication to develop special qualities in dogs. Today, dog keeping no longer corresponds to these qualities of dogs in many ways. We refer to the problems resulting from this and man's responsibility for the establishment of a man-dog relationship that is functional and responds to the dog's character. The abuse of certain dog behaviour by man has to be pursued consistently. In the same way we must also take care of an unforced integration of dogs into our society. PMID:1889368

    OBJECTIVE To investigate the prevalence and type of laryngeal abnormalities in dogs examined because of cough that did not have signs of upper airway disease and to compare the prevalence of those abnormalities among dogs with various respiratory tract diseases. DESIGN Prospective study. ANIMALS 138 dogs with cough that did not have signs of upper airway disease. PROCEDURES The study was conducted between July 2001 and October 2014 and included dogs examined for cough that had laryngoscopic and bronchoscopic examinations performed by 1 examiner. Laryngeal hyperemia and swelling were recorded, and laryngeal function was assessed before and after doxapram stimulation when indicated. Results were compared among dogs on the basis of cough duration (acute [ 2 months]) and disease diagnosed (inflammatory airway disease, airway collapse, lower respiratory tract infection, and eosinophilic bronchopneumopathy). RESULTS Laryngeal hyperemia was detected in 73 of 134 (54%) dogs with cough of subacute or chronic duration, and its prevalence did not vary significantly among dogs with various diseases. Thirteen dogs had laryngeal paresis, and 13 dogs had laryngeal paralysis; dysphonia (n = 2) and stridor (1) were uncommon findings in those dogs. The prevalence of laryngeal dysfunction (paresis or paralysis) did not differ significantly among diseases. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that 26 of 138 (19%) dogs examined because of cough alone had laryngeal dysfunction, which suggested that a complete laryngoscopic examination should be included in the diagnostic evaluation of dogs with cough.

  16. Important behavioral traits for predicting guide dog qualification.

    Arata, Sayaka; Momozawa, Yukihide; Takeuchi, Yukari; Mori, Yuji

    2010-05-01

    Guide dogs for the blind help blind people physically and mentally in their daily lives. Their qualifications are based on health, working performance and temperament; approximately 70% of dogs that fail to qualify are disqualified for behavioral reasons. In order to achieve early prediction of qualification, it would be essential as the first step to identify important temperament traits for guide dogs. Therefore, we administered a questionnaire consisting of 22 temperament items to experienced trainers to assess candidate dogs at the Japan Guide Dog Association after three months of training, which was at least three months prior to the final success (qualified as a guide dog) or failure (disqualified for behavioral reasons) judgment. Factor analyses of question items stably extracted three factors with high internal consistency, Distraction, Sensitivity and Docility. When we compared factor points between successful dogs and failed dogs, the successful dogs showed significantly and consistently lower Distraction points and higher Docility points. Additionally, Distraction points could predict qualification with 80.6% accuracy and detect 28.2% of the failed dogs that had higher Distraction points than any of the successful dogs. Of the nine question items not included in the three factors, two items (;Aggression' and ;Animal interest') were consistently associated with qualification. These results suggest that Distraction is stably assessable and has the strongest impact on success or failure judgment; therefore, it will be the first target to establish a behavioral test that may lead to early prediction of guide dog qualification.

    Kronisch, Robert L; Pfeiffer, Ronald P

    2002-01-01

    This article reviews the available literature regarding injuries in off-road bicyclists. Recent progress in injury research has allowed the description of several patterns of injury in this sport. Mountain biking remains popular, particularly among young males, although sales and participation figures have decreased in the last several years. Competition in downhill racing has increased, while cross-country racing has decreased somewhat in popularity. Recreational riders comprise the largest segment of participants, but little is known about the demographics and injury epidemiology of noncompetitive mountain cyclists. Most mountain bikers participating in surveys reported a history of previous injuries, but prospective studies conducted at mountain bike races have found injury rates of racing the risk of injury may be higher for women than men. Minor injuries such as abrasions and contusions occur frequently, but are usually of little consequence. Fractures usually involve the torso or upper extremities, and shoulder injuries are common. Head and face injuries are not always prevented by current helmet designs. Fatal injuries are rare but have been reported. Improvements in safety equipment, rider training and racecourse design are suggested injury prevention measures. The authors encourage continued research in this sport. PMID:12076178

    Full Text Available Aim: To assess the usefulness of duodenoscopy in the diagnosis of duodenal ulcers in dogs. Materials and Methods: Sick dogs with chronic gastrointestinal problems were physically examined and samples were collected for haematology, biochemistry and faecal examination. Duodenal biopsies, duodenal contents and brush cytology were obtained via duodenoscopy. Results: Seven duodenal ulcers cases were recorded, higher incidences was recorded in Labrador retriever, 2-4 years of aged male dogs. Significantly decreased Hb (9.10 ± 0.25 g/dl, RBCs (4.39 ± 0.19 mill/cu.mm and albumin (2.343b ± 0.13 g/dl level were noticed. Hyperaemia with ulceration of duodenal mucosa was observed. Conclusion: Duodenoscopy is very much useful for detection of duodenal ulceration and provided a sensitive technique for early diagnosis of mucosal lesions and ulceration. [Vet.

    Bergmann, Michèle; Friedl, Yvonne; Hartmann, Katrin

    2016-08-17

    Antibodies play an important role in the defense against infectious diseases. Passive immunization provides immediate protection through transfer of exogenous antibodies to a recipient. It is mainly used for prophylaxis in dogs and cats that failed to receive maternal antibodies through the colostrum or when there is an acute risk to acquire infectious diseases. Only a small number of placebo-controlled studies have been published regarding the therapeutic use of passive immunization in small animals. While positive effects were reported in cats with acute virus infections of the upper respiratory tract and in dogs with distemper, no statistically significant influence could be demonstrated in the treatment of canine parvovirosis. Prospective, double-blinded, and placebo-controlled studies using adequate numbers of patients are warranted for a definitive statement regarding the therapeutic and prophylactic use of passive immunization in dogs and cats.

    2015-01-01

    A 9 yr old castrated male golden retriever weighing 36 kg was presented for evaluation of progressive left pelvic limb paresis and fecal and urinary incontinence. MRI demonstrated an extradural, ovoid mass compressing the lumbar spinal cord. Surgical excision of the mass was performed. Histologically, the mass was consistent with hemangiosarcoma with no involvement of the adjacent vertebrae. The dog underwent a doxorubicin-based chemotherapy protocol with the addition of oral cyclophosphamide. After completion of chemotherapy, the dog was evaluated q 4 mo for restaging. Clinicopathological evidence of primary tumor recurrence or metastatic disease was not detected for 15 mo after initial diagnosis and treatment. To the authors' knowledge, this is the first report of a primary extradural hemangiosarcoma in the lumbar vertebral column in a dog. The clinical presentation, diagnosis, treatment, and outcome are also discussed. PMID:25955146

  2. Late effects of inhaled plutonium in dogs

    International Nuclear Information System (INIS)

    An overview is presented summarizing the effects of inhaled 239PuO2 and 238PuO2 in dogs with emphasis on dose-response relationships at low exposure levels. With the dose levels studied to date, pulmonary neoplasia was the primary cause of death in beagles 5 to 10 years after inhalation of 239PuO2. None of the dogs exposed to 239PuO2 developed bone tumors. Bone neoplasia was the primary cause of death 5 to 6 years after inhalation of 238PuO2; however, one of the dogs had pulmonary tumors in addition to bone tumors. The earliest indication of a biological effect after the inhalation of 239PuO2 or 238PuO2 was dose related lymphocytopenia

    The use of tracker dogs is the main method of finding hidden bodies, and in their search the dogs use typical scent patterns. "Electronic noses" can also be used to find and compare such patterns. Highly sensitive scent detectors have been successfully applied, e.g. in the examination of foodstuffs, in environmental tests and in material research. This study examined whether electronic sensors can be used to find bodies under outdoor conditions. The carcasses of two coneys were buried in soil at different depths. Over a period of 4 weeks, regular measurements were taken from the buried carcasses and from the control material. In addition, a "fingerprint" of the scent patterns was taken, and gas chromatography-mass spectrometry analyses were performed. Our findings indicate that it may be possible and viable to construct an "electronic body-tracking dog". PMID:19322580

    2016-01-01

    Gastritis and gastric ulcers are an important cause of morbidity and mortality in canine athletes. Although the majority of scientific work on this condition has been performed in ultraendurance racing sled dogs, this condition has been identified in other canine athletes, including sled dogs competing in shorter events and dogs performing off-leash explosive detection duties. The cause of the syndrome is unknown, but current hypotheses propose a link between exercise-induced hyperthermia and loss of gastric mucosal barrier function as an early event in the pathogenesis. Treatment is focused on prevention of clinical disease using acid secretion inhibitors, such as omeprazole, which has excellent efficacy in controlled clinical studies. PMID:27092307

    This report describes 2 cases of spontaneous aortic dissecting hematoma in young Border Collie and Border Collie crossbred dogs. Histology was performed in one of the cases involving an unusual splitting of the elastin present within the wall of the aorta, consistent with elastin dysplasia as described in Marfan syndrome in humans. The first case involved a young purebred Border Collie that died suddenly and the second case involved a Border Collie crossbred dog that died after a 1-month history of seizures. Gross lesions included pericardial tamponade with dissection of the ascending aorta in the former case and thoracic cavity hemorrhage, mediastinal hematoma, and aortic dissection in the latter. Histologic lesions in the case of the Border Collie crossbred dog included a dissecting hematoma of the ascending aorta with elastin dysplasia and right axillary arterial intimal proliferation.

  7. How to Know whether a Dog is Dangerous: Myth, Superstition and its Influence on the Human-dog Relationship

    Directory of Open Access Journals (Sweden)

    Tanja Kovačič

    2015-05-01

    Full Text Available The relationship between humans and dogs is complex and ambivalent. The dog was the first animal that Homo sapiens domesticated. This means that the human-dog relationship has lasted longer than any other human-animal relationships. Despite all this, mythological, symbolic and folkloristic traditions often depict dogs in a negative light and as a dangerous and threatening force from the underworld. Due to the belief that seeing an unknown dog can lead to misfortune, accident or even death, people were often afraid of dogs. People had to invent certain rules that could help them determine which dog was dangerous and which was not. Those rules had to change over time based on the fact that human-dog relationship is culturally and historically defined. The author analyses stories from in the Glasovi (Voices collection to show that, in the last few centuries in the territory of modern Slovenia, black dogs where most feared by humans. In contrast, nowadays the most feared dogs are those of the Pit Bull and some other breeds. Nevertheless, the folk superstitions and prejudice toward black dogs is still present in modern Western societies. In the English language “black dog” symbolizes depression. And some are still reluctant to adopt large black dogs from the animal shelters.

    2009-03-01

    The study raises the question of whether guide dogs and pet dogs are expected to differ in response to cues of referential communication given by their owners; especially since guide dogs grow up among sighted humans, and while living with their blind owners, they still have interactions with several sighted people. Guide dogs and pet dogs were required to respond to point, point and gaze, gaze and control cues of referential communication given by their owners. Results indicate that the two groups of dogs do not differ from each other, revealing that the visual status of the owner is not a factor in the use of cues of referential communication. Both groups of dogs have higher frequencies of performance and faster latencies for the point and the point and gaze cues as compared to gaze cue only. However, responses to control cues are below chance performance for the guide dogs, whereas the pet dogs perform at chance. The below chance performance of the guide dogs may be explained by a tendency among them to go and stand by the owner. The study indicates that both groups of dogs respond similarly in normal daily dyadic interaction with their owners and the lower comprehension of the human gaze may be a less salient cue among dogs in comparison to the pointing gesture.

    Full Text Available Aim: The present study has been envisaged to ascertain the old age for critical management of geriatric dogs considering the parameters of externally visible changes, haemato-biochemical alterations and urine analysis in geriatric dogs approaching senility. Materials and Methods: The study was undertaken in the Department of Veterinary Pathology in collaboration with Teaching Veterinary Clinic complex spanning a period of 1 year. For screening of geriatric dogs, standard geriatric age chart of different breeds was followed. The external characteristics such as hair coat texture, dental wear and tear, skin texture and glaucoma were taken as a marker of old age. Haematology, serum biochemistry and urine analysis were also included in the study. Results: External visible changes like greying of hair, dull appearance of hair coat, glaucoma, osteoarthritis, dental wear and tear were commonly encountered in the aged dogs. The haemoglobin, total erythrocyte count and packed cell volume showed a decreasing trend in the geriatric groups. Biochemical values like total protein, albumin, calcium level showed a decreasing trend while urea level with an increasing trend in geriatric dogs without any much alteration in serum glutamicoxaloacetic transaminse, serum glutamic-pyruvate transaminase, cholesterol and creatinine. Physical examination of urine revealed yellow, amber, red, deep red color with turbidity and higher specific gravity. Chemical examination revealed presence of protein, glucose, ketone bodies, blood and bilirubin on some cases. The culture and sensitivity test of the urine samples revealed presence of bacteria with sensitive and resistance to some antibiotics. Conclusion: External visible changes are still the golden standard of determining the old age in dogs. Haemato-biochemical evaluation can be useful for correlating with the pathophysiological status of the animal. Biochemical analysis of urine can be employed rightly as kidney

    Full Text Available Abstract Background Research on the uptake and transport of astaxanthin is lacking in most species. We studied the uptake of astaxanthin by plasma, lipoproteins and leukocytes in domestic dogs and cats. Methods Mature female Beagle dogs (18 to 19 mo old; 11 to 14 kg BW were dosed orally with 0, 0.1, 0.5, 2.5, 10 or 40 mg astaxanthin and blood taken at 0, 3, 6, 9, 12, 18 and 24 h post-administration (n = 8/treatment. Similarly, mature domestic short hair cats (12 mo old; 3 to 3.5 kg body weight were fed a single dose of 0, 0.02, 0.08, 0.4, 2, 5, or 10 mg astaxanthin and blood taken (n = 8/treatment at the same interval. Results Both dogs and cats showed similar biokinetic profiles. Maximal astaxanthin concentration in plasma was approximately 0.14 μmol/L in both species, and was observed at 6 h post-dosing. The plasma astaxanthin elimination half-life was 9 to 18 h. Astaxanthin was still detectable by 24 h in both species. In a subsequent study, dogs and cats were fed similar doses of astaxanthin daily for 15 to 16 d and astaxanthin uptake by plasma, lipoproteins, and leukocytes studied. In both species, plasma astaxanthin concentrations generally continued to increase through d 15 or 16 of supplementation. The astaxanthin was mainly associated with high density lipoprotein (HDL. In blood leukocytes, approximately half of the total astaxanthin was found in the mitochondria, with significant amounts also associated with the microsomes and nuclei. Conclusion Dogs and cats absorb astaxanthin from the diet. In the blood, the astaxanthin is mainly associated with HDL, and is taken up by blood leukocytes, where it is distributed to all subcellular organelles. Certain aspects of the biokinetic uptake of astaxanthin in dogs and cats are similar to that in humans.

    To identify genetic changes underlying dog domestication and reconstruct their early evolutionary history, we generated high-quality genome sequences from three gray wolves, one from each of the three putative centers of dog domestication, two basal dog lineages (Basenji and Dingo) and a golden jackal as an outgroup. Analysis of these sequences supports a demographic model in which dogs and wolves diverged through a dynamic process involving population bottlenecks in both lineages and post-divergence gene flow. In dogs, the domestication bottleneck involved at least a 16-fold reduction in population size, a much more severe bottleneck than estimated previously. A sharp bottleneck in wolves occurred soon after their divergence from dogs, implying that the pool of diversity from which dogs arose was substantially larger than represented by modern wolf populations. We narrow the plausible range for the date of initial dog domestication to an interval spanning 11-16 thousand years ago, predating the rise of agriculture. In light of this finding, we expand upon previous work regarding the increase in copy number of the amylase gene (AMY2B) in dogs, which is believed to have aided digestion of starch in agricultural refuse. We find standing variation for amylase copy number variation in wolves and little or no copy number increase in the Dingo and Husky lineages. In conjunction with the estimated timing of dog origins, these results provide additional support to archaeological finds, suggesting the earliest dogs arose alongside hunter-gathers rather than agriculturists. Regarding the geographic origin of dogs, we find that, surprisingly, none of the extant wolf lineages from putative domestication centers is more closely related to dogs, and, instead, the sampled wolves form a sister monophyletic clade. This result, in combination with dog-wolf admixture during the process of domestication, suggests that a re-evaluation of past hypotheses regarding dog origins is

    2016-06-01

    Full Text Available Canine urinary capillariosis is caused by the nematode Pearsonema plica. P. plica infection is seldomly detected in clinical practice mainly due to diagnostic limitations. This report describes six cases of urinary capillariosis in dogs from Italy. Recurrent cystitis was observed in one dog, whereas another patient was affected by glomerular amyloidosis. In the remaining animals, the infection was considered an incidental finding. Immature eggs of the parasite were observed with urine sediment examination in 3/6 patients. Increased awareness of the potential pathogenic role of P. plica. and clinical disease presentation could help identify infected animals.

    Full text. The purpose of this work came from the possibility of joining similar methodologies for determination of density, used in different areas, and provide more precise values of bone density by analyzing the mass attenuation coefficient. For over 20 years, The Applied Physics Laboratory, Department of Physics and Biophysics, IBB- UNESP, Botucatu campus, has been working in the determination of density in different areas, using the methods of immersion and gamma radiation attenuation. The results presented have excellent precision, due to the facility in obtaining and preparing samples, coupled to the large experience in the area. This study aims to determine the bone density of samples of mongrel dogs (dogs without defined breed) by the immersion method; to determine the mass attenuation coefficient of bones samples of mongrel dogs with a gamma radiation source; to discuss and to evaluate the methodological aspects involved in the optic densitometry used nowadays, presenting its advantages and disadvantages and, finally, to examine the effect of animal weight, age and sex on bone densitometry of medium-sized dogs. For this study, we use upper limbs samples, at the joint region humerus-radio-ulnar of after death mongrel dogs, assigned by the Department of Pathology, Faculty of Animal Science and Veterinary Medicine (UNESP-Botucatu) and by the Kennel of the city of Araras, Sao Paulo. This work is performed in three stages. In the first step is determined the density by the method of immersion in water, in the second step, is obtained the mass coefficient attenuation and, finally, in the third step are discussed the implemented methods and evaluate the density bone samples to establish correlations with the age, weight and sex parameters of each group of animals. Based on this methodology , we can find the average value for the mass attenuation coefficient of gamma radiation with energy 59,6, find variations in the values of bone densitometry in the same bone

  19. Cervical myelography in dogs using iohexol

    International Nuclear Information System (INIS)

    Iohexol, a non-ionic water-soluble radiographic contrast medium, was used for cervical myelography in dogs (10-17 kg). The animals remained clinically normal following myelography, with no evidence of seizures. At 10 days after myelography there was a slight, but significant (p<0.05) increase in neutrophils in the cerebrospinal fluid; these cell numbers had returned to normal by the time of necropsy at 60 days after myelography. This investigation suggests that iohexol may be suitable for clinical myelography in the dog. (orig.)

    Tracheal ultrasonography was performed to measure the width of the tracheal ring shadow and to assess the clinical relevance of these measurements for identifying tracheal collapse. The first tracheal ring width (FTRW) and thoracic inlet tracheal ring width (TITRW) were measured on both expiration and inspiration. The mean of the FTRW width (129 dogs) was greater in expiration (10.97 ± 1.02 mm, p = 0.001) than that in inspiration (9.86 ± 1.03 mm). For 51 normal dogs, the mean of the TITRW wid...

    Cats and dogs are assumed to drink similarly, but little is known about the actual physical mechanisms that dogs use to transport fluids when lapping. We observed the drinking behavior of a wide range of dogs across breeds and body size, and used physical experiments to mimic the motion of a dog’s tongue as it exits the water. Dogs accelerate the tongue upward more quickly than do cats, and then time their bite to coincide with the pinch-off of the column. The everyday experience of dogs as m...

  8. Spinal meningiomas in dogs: 13 cases (1972-1987)

    International Nuclear Information System (INIS)

    Medical records of 13 dogs with spinal meningiomas were reviewed. Breed predilections were not found. Males outnumbered females 9 to 4, and most of the dogs were middle-aged. All dogs had motor deficits of various degrees, and approximately half of the dogs had clinical signs of mild to moderate spinal pain. The remainder had histories of clinical signs suggestive of chronic discomfort. There was a prolonged (greater than 3 months) delay between the onset of signs and diagnosis, except in 3 dogs. The neurologic courses usually were progressive. Results of noncontrast spinal radiography were normal in 10 dogs; in 3 dogs, the lamina appeared scalloped. Results of myelography contributed to the correct diagnosis in 10 of 12 dogs; however, in 2 dogs, intradural/extramedullary tumors were thought to be intramedullary lesions. A preponderance of cervical meningiomas was found, accounting for 10 of 13 tumors. Lumbar meningiomas were found in the remaining 3 dogs. Surgery was performed in 9 of the dogs, six of which improved after surgery. Poor results were correlated with tumors that involved spinal cord segments of an intumescence, ventrally located tumors, iatrogenic trauma, and tumor invasion into adjacent neural parenchyma. Four of 13 spinal meningiomas were found to be invasive into the spinal cord itself

  9. Failure patterns following cobalt irradiation in dogs with nasal carcinoma

    International Nuclear Information System (INIS)

    The pattern of tumor recurrence was assessed in 24 dogs receiving cobalt radiation therapy for nasal carcinoma. Dogs were evaluated using nasal cavity computed tomography prior to treatment, and at 1, 3, 6 and 12 months after treatment, and at 6-month intervals thereafter if still alive. Dogs were treated with various combinations of total dose, and fraction size. Total doses were normalized to equivalent doses given in 3.0 Gy fractions. The extent of tumor regression or duration of tumor control were not dependent on absolute total dose, normalized total dose, or tumor type. The median duration of local control in all dogs was 312 days. Marked tumor regression was observed in 11 of the 24 dogs. Median duration of local control was significantly longer in dogs with marked tumor regression in comparison to dogs without tumor regression; 389 vs. 161 days respectively. When tumor recurrence was documented in dogs having tumor regression, the location of the recurrence was in the nasal cavity. No tumor recurred in a sinus or periorbital region, and only one geographic miss was detected. Tumor recurrence in the irradiated volume, including dogs with and without marked regression, was documented in 13 of the 24 dogs. The high local failure rate, coupled with the recurrence pattern in these dogs, suggests there may be an opportunity for improvement in local control through use of shrinking field techniques

    Five dogs with acquired myasthenia gravis (MG), verified via positive serum acetylcholine (ACh) receptor antibody concentrations, were treated with a drug protocol including azathioprine (AZA). Four of the five dogs were concurrently treated with pyridostigmine. Azathioprine was used as the sole immunosuppressive agent in four dogs. One dog was temporarily treated with a combination of an immunosuppressive dose of prednisone and AZA, then maintained on AZA as the sole immunosuppressive drug. Three patients experienced complete remission of clinical signs within three months of therapy. In the four dogs for which follow-up serum ACh receptor antibody concentrations were available, initial versus final concentrations decreased substantially (81%), coincident with clinical improvement. One dog died suddenly due to a suspected myasthenic crisis before attaining the target dose of AZA. Two of the four surviving dogs were euthanized approximately one and seven years after diagnosis. One of these two dogs was euthanized because of a rib osteosarcoma, and the other dog was euthanized because of paraparesis of undetermined cause. The remaining two dogs were alive and doing well at the time of final follow-up evaluation, approximately six months and one year after diagnosis. The use of AZA as a therapeutic agent for acquired canine MG has not been investigated. The cases presented in this report suggest a potentially important role for AZA in the treatment of acquired MG in dogs. PMID:10493415

    The U.S. Department of Energy is engaged in a suitability study for a potential geological repository at Yucca Mountain, Nevada, for the containment and storage of commercially generated spent fuel and defense high-level nuclear waste. There is growing recognition of the role that biotic factors could play in this repository, either directly through microbially induced corrosion (MIC), or indirectly by altering the chemical environment or contributing to the transport of radionuclides. As a first step toward describing and predicting these processes, a workshop was held on April 10-12, 1995, in Lafayette, California. The immediate aims of the workshop were: (1) To identify microbially related processes relevant to the design of a radioactive waste repository under conditions similar to those at Yucca Mountain. (2) To determine parameters that are critical to the evaluation of a disturbed subterranean environment. (3) To define the most effective means of investigating the factors thus identified

    2016-01-01

    Hot dust-obscured galaxies (hot DOGs) are a rare class of hyperluminous infrared galaxies identified with the Wide-field Infrared Survey Explorer (WISE) satellite. The majority of them is at high redshifts (z~2-3), at the peak epoch of star formation in the Universe. Infrared, optical, radio, and X-ray data suggest that hot DOGs contain heavily obscured, extremely luminous active galactic nuclei (AGN). This class may represent a short phase in the life of the galaxies, signifying the transition from starburst- to AGN-dominated phases. Hot DOGs are typically radio-quiet, but some of them show mJy-level emission in the radio (microwave) band. We observed four hot DOGs using the technique of very long baseline interferometry (VLBI). The 1.7-GHz observations with the European VLBI Network (EVN) revealed weak radio features in all sources. The radio is free from dust obscuration and, at such high redshifts, VLBI is sensitive only to compact structures that are characteristic of AGN activity. In two cases (WISE J07...

    Canine kobuviruses (CaKVs) are newly recognized picornaviruses recently detected in dogs in the US. By molecular analysis of the whole genome, CaKV that appeared genetically closest to the murine kobuvirus (MuKV) and to the human Aichi virus (AiV), may be classified in the Kobuvirus genus as new genotype (CaKV type 1) within the species Aichivirus A. To date, there are no information on the epidemiology of these novel viruses in other continents. In this study, by screening a collection of 256 dog fecal samples either from diarrhoeic or asymptomatic animals, CaKV was identified in six specimens with an overall prevalence of 2.34% (6/256). All the positive dogs presented diarrhea and were found to be infected by CaKV alone or in mixed infections with canine coronavirus (CCoV) and/or canine parvovirus type 2 (CPV-2). By molecular analysis of the partial 3D gene, all the strains detected displayed a close relatedness with the CaKVs recently identified in the US. This study provides evidence that CaKVs circulate in diarrhoeic dogs in Italy and are not geographically restricted to the North American continent, where they were first signaled. PMID:23806200

    The serum or plasma biochemical profile is essential in the diagnosis and monitoring of systemic disease in veterinary medicine, but current reference intervals typically take no account of breed-specific differences. Breed-specific hematological phenotypes have been documented in the domestic dog, but little has been published on serum biochemical phenotypes in this species. Serum biochemical profiles of dogs in which all measurements fell within the existing reference intervals were retrieved from a large veterinary database. Serum biochemical profiles from 3045 dogs were retrieved, of which 1495 had an accompanying normal glucose concentration. Sixty pure breeds plus a mixed breed control group were represented by at least 10 individuals. All analytes, except for sodium, chloride and glucose, showed variation with age. Total protein, globulin, potassium, chloride, creatinine, cholesterol, total bilirubin, ALT, CK, amylase, and lipase varied between sexes. Neutering status significantly impacted all analytes except albumin, sodium, calcium, urea, and glucose. Principal component analysis of serum biochemical data revealed 36 pure breeds with distinctive phenotypes. Furthermore, comparative analysis identified 23 breeds with significant differences from the mixed breed group in all biochemical analytes except urea and glucose. Eighteen breeds were identified by both principal component and comparative analysis. Tentative reference intervals were generated for breeds with a distinctive phenotype identified by comparative analysis and represented by at least 120 individuals. This is the first large-scale analysis of breed-specific serum biochemical phenotypes in the domestic dog and highlights potential genetic components of biochemical traits in this species.

  1. STRAY DOG DETECTION IN WIRED CAMERA NETWORK

    2013-08-01

    Full Text Available Existing surveillance systems impose high level of security on humans but lacks attention on animals. Stray dogs could be used as an alternative to humans to carry explosive material. It is therefore imperative to ensure the detection of stray dogs for necessary corrective action. In this paper, a novel composite approach to detect the presence of stray dogs is proposed. The captured frame from the surveillance camera is initially pre-processed using Gaussian filter to remove noise. The foreground object of interest is extracted utilizing ViBe algorithm. Histogram of Oriented Gradients (HOG algorithm is used as the shape descriptor which derives the shape and size information of the extracted foreground object. Finally, stray dogs are classified from humans using a polynomial Support Vector Machine (SVM of order 3. The proposed composite approach is simulated in MATLAB and OpenCV. Further it is validated with real time video feeds taken from an existing surveillance system. From the results obtained, it is found that a classification accuracy of about 96% is achieved. This encourages the utilization of the proposed composite algorithm in real time surveillance systems.

    Xenoulis, P G

    2015-01-01

    Pancreatitis is the most common disorder of the exocrine pancreas in both dogs and cats. Ante-mortem diagnosis of canine and feline pancreatitis can be challenging. The clinical picture of dogs and cats with pancreatitis varies greatly (from very mild to severe or even fatal) and is characterised by non-specific findings. Complete blood count, serum biochemistry profile and urinalysis should always be performed in dogs and cats suspected of having pancreatitis, although findings are not-specific for pancreatitis. Serum amylase and lipase activities and trypsin-like immunoreactivity (TLI) concentrations have no or only limited clinical value for the diagnosis of pancreatitis in either dogs or cats. Conversely, serum pancreatic lipase immunoreactivity (PLI) concentration is currently considered to be the clinicopathological test of choice for the diagnosis of canine and feline pancreatitis. Abdominal radiography is a useful diagnostic tool for the exclusion of other diseases that may cause similar clinical signs to those of pancreatitis. Abdominal ultrasonography can be very useful for the diagnosis of pancreatitis, but this depends largely on the clinician's experience. Histopathological examination of the pancreas is considered the gold standard for the diagnosis and classification of pancreatitis, but it is not without limitations. In clinical practice, a combination of careful evaluation of the animal's history, serum PLI concentration and abdominal ultrasonography, together with pancreatic cytology or histopathology when indicated or possible, is considered to be the most practical and reliable means for an accurate diagnosis or exclusion of pancreatitis compared with other diagnostic modalities.

    Poole, David C; Erickson, Howard H

    2011-01-01

    Evolutionary forces drive beneficial adaptations in response to a complex array of environmental conditions. In contrast, over several millennia, humans have been so enamored by the running/athletic prowess of horses and dogs that they have sculpted their anatomy and physiology based solely upon running speed. Thus, through hundreds of generations, those structural and functional traits crucial for running fast have been optimized. Central among these traits is the capacity to uptake, transport and utilize oxygen at spectacular rates. Moreover, the coupling of the key systems--pulmonary-cardiovascular-muscular is so exquisitely tuned in horses and dogs that oxygen uptake response kinetics evidence little inertia as the animal transitions from rest to exercise. These fast oxygen uptake kinetics minimize Intramyocyte perturbations that can limit exercise tolerance. For the physiologist, study of horses and dogs allows investigation not only of a broader range of oxidative function than available in humans, but explores the very limits of mammalian biological adaptability. Specifically, the unparalleled equine cardiovascular and muscular systems can transport and utilize more oxygen than the lungs can supply. Two consequences of this situation, particularly in the horse, are profound exercise-induced arterial hypoxemia and hypercapnia as well as structural failure of the delicate blood-gas barrier causing pulmonary hemorrhage and, in the extreme, overt epistaxis. This chapter compares and contrasts horses and dogs with humans with respect to the structural and functional features that enable these extraordinary mammals to support their prodigious oxidative and therefore athletic capabilities.

The first tracheal ring width (FTRW) and thoracic inlet tracheal ring width (TITRW) were measured on both expiration and inspiration. The mean of the FTRW width (129 dogs) was greater in expiration (10.97 plusmn; 1.02 mm, p = 0.001) than that in inspiration (9.86 plusmn; 1.03 mm). For 51 normal dogs, the mean of the TITRW width was greater in expiration (9.05 plusmn; 1.52 mm, p = 0.001) than in inspiration (8.02 plusmn; 1.43 mm). For 78 tracheal collapse dogs, the mean of the TITRW width was greater in expiration (15.89 plusmn; 1.01 mm, p = 0.001) than in inspiration (14.85 plusmn; 1.17 mm). The TITRW/FTRW ratio of the normal dogs was higher (p = 0.001) in expiration (0.81 plusmn; 0.09) than that in inspiration (0.79 plusmn; 0.10). When compared between the normal and tracheal collapse dogs, the TITRW/FTRW ratio was also increased (p = 0.001) both in expiration (1.54 plusmn; 0.09) and inspiration (1.47 plusmn; 0.08), respectively. Based on these results, the cutoff level of the TITRW/FTRW ratio was statistically analyzed according to the receiver operating characteristic curve and it could be set at 1.16 in expiration and at 1.13 in inspiration. We have demonstrated that tracheal ultrasonography is a useful technique for the evaluation of tracheal collapse and it can be a supportive tool together with the radiographic findings for making the correct diagnosis.

    Giardia intestinalis is a pathogenic protozoan which infects humans and a wide range of animals including dogs. Giardia infections in dogs have been reported by several authors. Prevalence of Giardia varies widely depending on the detection method, geographic localization, and population studied. The objective of the study reported here was to determine the prevalence of giardiasis in German Shepherd Dogs in a breeding unit. In our trial conducted over 18 months, 28 bitches, 5 adult males and 101 puppies (between 1.5 and 12 months old) were subjected to individual fecal examination for Giardia cysts, coccidial oocysts and helminth ova. Total 494 individual fecal samples were examined by the magnesium sulphate flotation technique (1.30 sp. gr) and Giardia cysts were detected in 36.2% of fecal samples. Giardia cysts were observed in 1 of 29 (3.4%) fecal samples from adult males, 11 of 157 (7.0%) fecal samples from bitches and 164 of 308 (53.2%) puppies' fecal specimens. No association between bouts of diarrhea and peaks of Giardia cysts shedding could be demonstrated. The source of infection for the pups was not ascertained, as no temporal association between shedding of Giardia cyst by bitches and their litters could be demonstrated. The majority of pups had passed peak of Giardia cyst shedding between week 6 of age 12 week of age. When Giardia infection was detected, the dogs were treated with either ornidazole (Avrazor, Léciva) at 25 mg/kg or metronidazole (Entizol, Polfa) 50 mg/kg for three to five days. Within seven days of completing a course of treatment fecal examinations were carried out on each dog to determine whether treatment had been effective.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8184530

    The Red Dog sediment-hosted deposit in the De Long Mountains of northern Alaska is the largest Zn producer in the world. Main stage mineralization is characterized by massive sulfide ore and crosscutting subvertical veins. Although the vein mineralization is clearly younger than the massive ore, the exact temporal relationship between the two is unclear. Re-Os geochronology of pyrite is used to determine the absolute age of main stage ore at Red Dog. A 10-point isochron on both massive and vein pyrite yields an age of 338.3 ?? 5.8 Ma and is interpreted to represent the age of main stage ore. The Re-Os data indicate that both massive and vein ore types are coeval within the resolution of the technique. Formation of the Red Dog deposit was associated with extension along a passive continental margin, and therefore the Re-Os age of main stage ore constrains the timing of rifting as well as the age of the host sedimentary rocks. Sphalerite from both massive and vein ore yields imprecise ages and shows a high degree of scatter compared to pyrite. We suggest that the Re-Os systematics of sphalerite can be disturbed and that this mineral is not reliable for Re-Os geochronology. ?? 2004 by Economic Geology.

  15. a Novel Approach to Veterinary Spatial Epidemiology: Dasymetric Refinement of the Swiss Dog Tumor Registry Data

    In spatial epidemiology, disease incidence and demographic data are commonly summarized within larger regions such as administrative units because of privacy concerns. As a consequence, analyses using these aggregated data are subject to the Modifiable Areal Unit Problem (MAUP) as the geographical manifestation of ecological fallacy. In this study, we create small area disease estimates through dasymetric refinement, and investigate the effects on predictive epidemiological models. We perform a binary dasymetric refinement of municipality-aggregated dog tumor incidence counts in Switzerland for the year 2008 using residential land as a limiting ancillary variable. This refinement is expected to improve the quality of spatial data originally aggregated within arbitrary administrative units by deconstructing them into discontinuous subregions that better reflect the underlying population distribution. To shed light on effects of this refinement, we compare a predictive statistical model that uses unrefined administrative units with one that uses dasymetrically refined spatial units. Model diagnostics and spatial distributions of model residuals are assessed to evaluate the model performances in different regions. In particular, we explore changes in the spatial autocorrelation of the model residuals due to spatial refinement of the enumeration units in a selected mountainous region, where the rugged topography induces great shifts of the analytical units i.e., residential land. Such spatial data quality refinement results in a more realistic estimation of the population distribution within administrative units, and thus, in a more accurate modeling of dog tumor incidence patterns. Our results emphasize the benefits of implementing a dasymetric modeling framework in veterinary spatial epidemiology.

    The domestication of the dog from the wolf was a key step in the pathway that led to the Neolithic revolution. The earliest fossil dogs, dated to the end of the last glacial period (17,000 to 12,000 years ago), have been found in Russia, Germany and the Middle East. No dogs are represented in the naturalistic art of the European Upper Palaeolithic, suggesting that dogs were introduced at a later date. Genetic studies of extant dog and wolf mitochondrial DNA sequences were interpreted in favour of multiple dog founding events as early as 135-76,000 years ago, or of a single origin in East Asia, 40,000 or 15,000 years ago. Our study included mitochondrial DNA sequences from Italian fossil bones attributed to three Late Pleistocene-Early Holocene wolves (dated from a15,000 to a10,000 14C years ago) and two dogs, dated to a4000 and a3000 14C years ago respectively. Taking paleogeography into account, our phylogenetic data point to a contribution of European wolves to the three major dog clades, in agreement with archaeozoological data. Our phylogeographic studies also suggest genetic differentiation of dogs and wolves related to isolation by geographic distance, supporting multicentric origins of dogs from wolves throughout their vast range of sympatry.

    Patellar luxation (PL) is one of the major hereditary orthopaedic abnormalities observed in a variety of dog breeds. When the patellae move sideways out of the trochlear groove, this is called PL. The PL score varies between dogs from normal to very severe. Reducing the prevalence of PL by breeding could prevent surgery, thereby improve welfare. Orthopaedic specialists differentiate between normal and loose patellae, where the patellae can be moved to the edge of the trochlear groove, considering scoring loose patellae as normal in the future. Loose patellae are considered acceptable for breeding so far by the breeding organization. The aim of this study was to analyse the genetic background of PL to decide on the importance of loose patellae when breeding for healthy dogs. Data are available from two dog breeds, that is Flat-coated Retrievers (n = 3808) and Kooiker dogs (n = 794), with a total of 4602 dogs. Results show that loose patellae indicate that dogs are genetically more susceptible to develop PL because family members of the dogs with loose patellae showed more severe PL. In addition, the estimated breeding values for dogs with loose patellae indicate that breeding values of dogs with loose patellae were worse than breeding values obtained for dogs with a normal score. Given these results, it is advised to orthopaedic specialists to continue to score loose patellae as a separate class and to dog breeders to minimize the use of dogs in breeding with a genetically higher susceptibility for PL.

    Tail docking and ear cropping are two surgical procedures commonly performed on many dog breeds. These procedures are classified as medically unnecessary surgeries whose purpose is primarily cosmetic. Available attitude research surrounding these controversial practices has been limited to surveys of veterinarians and dog breeders familiar with both practices. The aim of this project was to: 1) assess public awareness of tail docking and ear cropping, 2) determine whether physical alteration of a dog affects how the dog, and 3) owner are perceived. In Experiment 1 awareness was measured using a combination of both explicit and implicit measures. We found that 42% of participants (n = 810) were unable to correctly explain the reason why tail docked and ear cropped dogs had short ears and tails. Similarly, an implicit measure of awareness ('nature vs nurture task'), found that the majority of participants believed short tails and erect ears were a consequence of genetics rather than something the owner or breeder had done. The results obtained in Experiment 2 (n = 392) provide evidence that ear cropped and tail docked dogs are perceived differently than an identical dog in its 'natural' state. Modified dogs were perceived as being more aggressive, more dominant, less playful and less attractive than natural dogs. Experiment 3 (n = 410) is the first evidence that owners of modified dogs are perceived as being more aggressive, more narcissistic, less playful, less talkative and less warm compared to owners of natural dogs. Taken together, these results suggest that although a significant proportion of subjects appear unaware of the practices of tail docking and ear cropping in dogs, these procedures have significant impacts on how modified dogs and their owners are perceived by others.

    This paper reports on endoparasite infections diagnosed in 2012 by standard coproscopical techniques and coproantigen Giardia ELISA in 165 dogs used for sheep herding in 36 farms in central Germany. The overall prevalence of dogs with evidence of endoparasite infections was 27.3% (95% CI 20.6-34.7). The most frequently identified faecal forms were those of ascarids (Toxocara, 6.7%; Toxascaris 3.6%), hookworms (5.5%) and taeniid cestodes (4.2%), followed by those of Trichuris whipworms (3.0%), Capillaria aerophila (1.8%), Angiostrongylus and Crenosoma lungworms (1.2% each) and Cystoisospora canis coccidians (0.6%). Molecular identification demonstrated the seven dogs shedding taeniid eggs positive for Taenia (T.) species tapeworms (five, T. hydatigena; one, T. ovis; one Taenia sp.). Screening of the faeces with the coproantigen ELISA revealed Giardia specific antigen in 5.5% of the samples. The majority of the dogs had evidence of single endoparasite infections (22.4%) while evidence for infection with two or three parasites concurrently was found in six (3.6%) and two (1.2%) of the dogs, respectively. Dogs ≤ 1 year (n = 19) were parasitized more frequently (p Giardia spp. (21.1% vs. 3.4%) than older dogs (n = 146). Dogs which had been wormed within six months of examination tested less frequently positive for gastrointestinal helminths compared to dogs not wormed (11.1% vs. 25.0%; p = 0.0567). In addition, ear swabs taken from 43 sheep dogs in 2012 were examined, and Otodectes cynotis mites were extracted from one dog. Identification of ectoparasites collected by full body search and combing from 113 sheep dogs in the years 2011 to 2013 revealed infestation of fleas and ticks (each up to five specimens per dog) on 13 and 108 dogs, respectively, with nine dogs carrying both fleas and ticks. Archaeopsylla erinacei, Ctenocephalides (C) canis, C. felis and Pulex irritans fleas were identified from one, three, two and eleven dogs, respectively. Dermacentor reticulatus

    International Nuclear Information System (INIS)

    Eight dogs with renal neoplasia were radiographically and sonographically examined. An enlarged, nonopacified kidney was seen on the excretory urogram in four dogs, but differentiation between a solid mass or severe hydronephrosis was not possible. The excretory urogram suggested an avascular lesion in one kidney, but differentiation between solid or cystic disease was not possible. Renal neoplasia was diagnosed in two dogs by excretory urography. Radiographic examination suggested splenic neoplasia in one dog. Solid masses were sonographically diagnosed in all dogs. A metastatic lesion was sonographically diagnosed in the opposite kidney of one dog that was missed on the radiographic examination. Ultrasonography complemented radiography as a diagnostic modality in eliciting additional information on renal disease. Sonograms did not allow determination of tumor cell type or whether the tumor was benign or malignant

    In humans, chronic infection with the gammaherpesvirus Epstein-Barr virus is usually asymptomatic; however some infected individuals develop hematological and epithelial malignancies. The exact role of EBV in lymphomagenesis is poorly understood partly because of the lack of clinically relevant animal models. Here we report the detection of serological responses against EBV capsid antigens in healthy dogs and dogs with spontaneous lymphoma and that dogs with the highest antibody titers have B cell lymphoma. Moreover, we demonstrate the presence of EBV-like viral DNA and RNA sequences and Latent Membrane Protein-1 in malignant lymph nodes of dogs with lymphoma. Finally, electron microscopy of canine malignant B cells revealed the presence of classic herpesvirus particles. These findings suggest that dogs can be naturally infected with an EBV-like gammaherpesvirus that may contribute to lymphomagenesis and that dogs might represent a spontaneous model to investigate environmental and genetic factors that influence gammaherpesvirus-associated lymphomagenesis in humans.

    Malassezia (M.) pachydermatis is the lipophilic yeast, which is normally present on the skin and in the ear canal of dogs but under certain conditions it may cause dermatitis and otitis. There is less known about the occurrence of lipid-dependent Malassezia species in dogs. The aim of this study was to detect whether lipid-dependent yeasts are part of the normal microflora in dogs. Two groups of animals were selected for comparison. The group of healthy dogs contained samples of 118 individuals and the group of dogs with cutaneous lesions or otitis externa comprised 328 dogs. The isolates of Malassezia were identified by using genotypic methods that allow the precise identification. M. pachydermatis was the most frequently isolated species in this study (121 isolates). Only four isolates were identified as M. furfur and one isolate was identified as M. nana. PMID:27529998

    Full Text Available Although significant animal suffering caused by preventable diseases is frequently seen in developing countries, reports of this are scarce. This report describes avoidable animal suffering owing to a suspected canine distemper (CD outbreak in unvaccinated dogs owned by low-income families in Mozambique that killed approximately 200 animals. Affected dogs exhibited clinical signs, and gross and microscopic lesions compatible with CD. Immunohistochemical staining confirmed the presence of canine distemper virus (CDV in the kidney of one dog from the cohort. This brief communication again illustrates that large outbreaks of CDV in unvaccinated dogs occur and that large-scale avoidable suffering and threats to the health of dogs and wild canines continue. Mass vaccination supported by government and non-government organisations is recommended.Keywords: Canine distemper; dogs; outbreak; animal welfare; Mozambique

    Some dog breeds, including the German shepherd dog (GSD), are predisposed to immune-related disorders. The authors prospectively described development of serum and faecal IgA and serum IgE in GSD from puppies until adulthood and the relationship between mothers and their offspring. Further, the authors tested whether dogs with lower serum IgA also have low faecal IgA and/or serum IgE. To reveal whether any of the parameters could be proven to influence the immune response, the authors also measured serum IgG against canine distemper virus (CDV). To test their hypothesis, the authors used linear mixed models to investigate the relationship of serum IgA, serum IgE and faecal IgA levels in litters and their mothers. Fifteen GSD bitches beginning at 42 days of pregnancy and subsequently all of their offspring (n=83 puppies), reared under well-controlled conditions, were included. All dogs came from the kennel of the Swedish Armed Forces. Serum IgE, serum IgA and faecal IgA levels were lower in seven-week-old puppies than at one year of age. There was no relationship in Ig concentrations between bitches and their puppies at seven weeks of age. Dogs with higher faecal IgA had higher IgG titres against CDV, indicating a favourable systemic immune status. PMID:27547424

    Varying levels of rabies antibody have been detected both by Enzyme Linked Immunosorbent Assay (ELISA) and Rapid Fluorescent Focus Inhibition Test (RFFIT) in the sera collected from wild and domestic canids in the Bale Mountains National Park (BMNP) of Southern Ethiopia. Rabies antibody was detected in 80% (8 out of 10) of domestic dog samples, 13.3% (2 out of 15) of Simien jackal samples and in one common jackal. Rabies virus was isolated from one dog in an area where contact with the Simien jackal could possibly occur. All samples examined from wild rodents as possible reservoir hosts for rabies were found negative. The presence of large proportion of susceptible Simien jackals in the population should be a cause of great concern in saving this endangered species from the ravages of rabies. PMID:1642078

    Full Text Available BACKGROUND: Canine hip dysplasia (HD is a common polygenic trait characterized by hip malformation that results in osteoarthritis (OA. The condition in dogs is very similar to developmental dysplasia of the human hip which also leads to OA. METHODOLOGY/PRINCIPAL FINDINGS: A total of 721 dogs, including both an association and linkage population, were genotyped. The association population included 8 pure breeds (Labrador retriever, Greyhounds, German Shepherd, Newfoundland, Golden retriever, Rottweiler, Border Collie and Bernese Mountain Dog. The linkage population included Labrador retrievers, Greyhounds, and their crosses. Of these, 366 dogs were genotyped at ∼22,000 single nucleotide polymorphism (SNP loci and a targeted screen across 8 chromosomes with ∼3,300 SNPs was performed on 551 dogs (196 dogs were common to both sets. A mixed linear model approach was used to perform an association study on this combined association and linkage population. The study identified 4 susceptibility SNPs associated with HD and 2 SNPs associated with hip OA. CONCLUSION/SIGNIFICANCE: The identified SNPs included those near known genes (PTPRD, PARD3B, and COL15A1 reported to be associated with, or expressed in, OA in humans. This suggested that the canine model could provide a unique opportunity to identify genes underlying natural HD and hip OA, which are common and debilitating conditions in both dogs and humans.

  19. Getting Beyond Yucca Mountain - 12305

    International Nuclear Information System (INIS)

    The U.S. Department of Energy has terminated the Yucca Mountain repository project. The U.S. Nuclear Regulatory Commission has indefinitely suspended the Yucca Mountain licensing proceeding. The presidentially-appointed Blue Ribbon Commission (BRC) on America's Nuclear Future is preparing a report, due in January 2012, to the Secretary of Energy on recommendations for a new national nuclear waste management and disposal program. The BRC Draft Report published in July 2011 provides a compelling critique of the past three decades failed efforts in the United States to site storage and disposal facilities for spent nuclear fuel (SNF) and high-level radioactive waste (HLW). However, the BRC Draft Report fails to provide detailed guidance on how to implement an alternative, successful approach to facility site selection. The comments submitted to the BRC by the State of Nevada Agency for Nuclear Projects provide useful details on how the US national nuclear waste program can get beyond the failed Yucca Mountain repository project. A detailed siting process, consisting of legislative elements, procedural elements, and 'rules' for volunteer sites, could meet the objectives of the BRC and the Western Governors Association (WGA), while promoting and protecting the interests of potential host states. The recent termination of the proposed Yucca Mountain repository provides both an opportunity and a need to re-examine the United States' nuclear waste management program. The BRC Draft Report published in July 2011 provides a compelling critique of the past three decades failed efforts in the United States to site storage and disposal facilities for SNF and HLW. It is anticipated that the BRC Final report in January 2012 will recommend a new general course of action, but there will likely continue to be a need for detailed guidance on how to implement an alternative, successful approach to facility site selection.

    2015-01-01

    Previous research has suggested that owners’ attitude to their family dogs may contribute to a variety of behaviour problems in the dog, and authors assume that dogs with separation-related disorder (SRD) attach differently to the owner than typical dogs do. Our previous research suggested that these dogs may have an insecure attachment style. In the present study we have investigated whether owners’ attachment style, personality traits and the personality of the dog influence the occurrence ...

  4. Biological effects of inhaled cigarette smoke in beagle dogs

    International Nuclear Information System (INIS)

    A group of twenty dogs has received up to 7 yr of daily cigarette smoking (10 cigarettes per day, 5 days per week), using realistic methods of oral inhalation and nose-plus-mouth exhalation. Three dogs that received 20 cigarettes per day over 9 mo developed respiratory tract lesions, including pleural thickening, alveolar septal fibrosis, vesicular emphysema, and chronic bronchitis, more rapidly than dogs receiving 10 cigarettes per day

  5. Thoracic radiographic features of anticoagulant rodenticide toxicity in fourteen dogs

    International Nuclear Information System (INIS)

    Thoracic radiographs and clinical records from 14 dogs with confirmed anticoagulant rodenticide toxicity were reviewed. Twelve of the 14 dogs were presented with a chief complaint of respiratory distress, and 12 had elevated prothrombin and activated partial thromboplastin times consistent with a coagulopathy secondary to a clotting factor deficiency. Thoracic radiographs of the 14 dogs were reviewed and abnomalities included increased mediastinal soft tissue opacity with extra and intrathoracic tracheal narrowing (4/14), increased mediastinal soft tissue opacity without tracheal narrowing (8/14), variable degrees of pleural effusion (13/14) and generalized, patchy interstitial/alveolar pulmonary infiltrates (8/14). Radiographic evidence of cardiomegaly and pulmonary artery abnormalities consistent with concurrent heartworm infestation were detected in one dog. In four dogs, dramatic tracheal narrowing was identified on the lateral thoracic radiograph caused by either mediastinal hemorrhage compressing the trachea or submucosal hemorrhage within the tracheal lumen. The trachea was displaced in a ventral direction in two dogs, and extra and intrathoracic luminal diameter narrowing was evident cranially in all four dogs. Two of these four dogs had soft tissue opacity within the dorsal trachea that extended from the larynx to the intrathoracic trachea. Twelve of the 14 dogs survived with standard treatment protocols utilizing injectable and oral vitamin K1. One dog died from pancreatitis and disseminated intravascular coagulopathy. The other dog died soon after presentation due to severe, disseminated hemorrhage. Follow-up thoracic radiographs were made in four dogs that survived and showed resolution of the mediastinal, pleural and pulmonary changes within one to five days after the initiation of vitamin K1 therapy

  15. The skin microbiome in healthy and allergic dogs.

    Directory of Open Access Journals (Sweden)

    Aline Rodrigues Hoffmann

    Full Text Available BACKGROUND: Changes in the microbial populations on the skin of animals have traditionally been evaluated using conventional microbiology techniques. The sequencing of bacterial 16S rRNA genes has revealed that the human skin is inhabited by a highly diverse and variable microbiome that had previously not been demonstrated by culture-based methods. The goals of this study were to describe the microbiome inhabiting different areas of the canine skin, and to compare the skin microbiome of healthy and allergic dogs. METHODOLOGY/PRINCIPAL FINDINGS: DNA extracted from superficial skin swabs from healthy (n = 12 and allergic dogs (n = 6 from different regions of haired skin and mucosal surfaces were used for 454-pyrosequencing of the 16S rRNA gene. Principal coordinates analysis revealed clustering for the different skin sites across all dogs, with some mucosal sites and the perianal regions clustering separately from the haired skin sites. The rarefaction analysis revealed high individual variability between samples collected from healthy dogs and between the different skin sites. Higher species richness and microbial diversity were observed in the samples from haired skin when compared to mucosal surfaces or mucocutaneous junctions. In all examined regions, the most abundant phylum and family identified in the different regions of skin and mucosal surfaces were Proteobacteria and Oxalobacteriaceae. The skin of allergic dogs had lower species richness when compared to the healthy dogs. The allergic dogs had lower proportions of the Betaproteobacteria Ralstonia spp. when compared to the healthy dogs. CONCLUSIONS/SIGNIFICANCE: The study demonstrates that the skin of dogs is inhabited by much more rich and diverse microbial communities than previously thought using culture-based methods. Our sequence data reveal high individual variability between samples collected from different patients. Differences in species richness was also seen between

    2011-02-01

    From 2004 to 2009, the digestive tracts of 111 dogs from suburban areas around Tirana, Albania, were examined for intestinal helminths. In addition, rectal faecal samples of all dogs were examined for protozoan infections and 48 faecal samples from dogs >6 months of age were processed with the Baermann technique to test for the excretion of lungworm larvae. The heart and pulmonary arteries of 30 dogs >6 months of age also were examined for nematode parasites. The intestinal parasite fauna of the dogs included three protozoan species (Cystoisospora canis, Cystoisospora ohioensis/burrowsi, Sarcocystis spp.), three cestode species (Dipylidium caninum, Taenia hydatigena, Echinococcus granulosus), five nematode species (Ancylostoma caninum, Uncinaria stenocephala, Toxocara canis, Toxascaris leonina, Trichuris vulpis) and one acanthocephalan (Centrorhynchus buteonis). Rates of infection were: 15.3% for C. canis, 31.5% for C. ohioensis/burrowsi, 1.8% for Sarcocystis spp., 65.8% for D. caninum, 16.2% for T. hydatigena, 2.7% for E. granulosus (genotype G1), 13.5% for A. caninum, 64.9% for U. stenocephala, 75.7% for T. canis, 0.9% for T. leonina, 21.6% for T. vulpis and 0.9% for C. buteonis. Up to six species of gastrointestinal parasites were found per dog. The 63 ≤ 6-month-old dogs harboured significantly (p6 months of age harboured significantly (pvulpis compared to younger dogs. Conversely, the younger dogs harboured significantly (p6 months of age: Male dogs harboured significantly (p<0.05) more tapeworms than female dogs. Based on faecal examination, there was no indication for lungworm infection; however, two adult heartworms (Dirofilaria immitis) were found in the right ventricle of one dog. PMID:20878182

    Author Summary As a result of selective breeding practices, modern dogs display a multitude of head shapes. Breeds such as the Pug and Bulldog popularize one of these morphologies, termed “brachycephaly.” A short, upward-pointing snout, a massive and rounded head, and an underbite typify brachycephalic breeds. Here, we have coupled the phenotypes collected from museum skulls with the genotypes collected from dogs and identified five regions of the dog genome that are associated with canine br...

    Full Text Available A nine-year-old female Boxer was diagnosed with osteosarcoma in the right hind limb. During imaging exams to investigate the occurrence of metastasis, it was observed a mass in the abdominal cavity. A laparotomy was performed, and the mass was detected in the left ovary. Intraoperative fine-needle aspirates were made and showed spindle cells with moderate cellular pleomorphism and neutrophils. The cytological findings were not compatible with osteosarcoma metastasis. The mass was excised and submitted to histopathological evaluation. The microscopic examination showed a proliferation of spindle cells forming small vascular channels and a trabecular pattern interspersed by discrete to moderate collagenous stroma. The cells showed moderate cellular pleomorphism and high mitotic index. There was abundant necrosis and multifocal hemorrhage. The definitive diagnosis was hemangiosarcoma. This is a rare primary ovary tumor in dogs with just one previous report in veterinary literature. However, it should be considered as a differential diagnosis in female dogs with ovary mass.

    Gastric emptying of organic acids was studied in 6 healthy mongrel dogs. After chronic esophagostomies were performed according to the method of Komarov, a total of 340 test meals were instilled. Each test meal consisted of 300 ml of 6 different organic acids with decreasing molecular weight and different concentrations. After the experiments were achieved, each dog underwent a proximal gastric vagotomy according to the method of Amdrup, and experiments with citric acid were repeated. The results may be summarized as follows: multiple stepwise regression analysis of the data is consistent with a model in which gastric emptying of organic acids is regulated by 3 receptors. The receptors respond to concentration of the organic acid, the actual volume, and the type of acid. The volume receptor is located in the corpus of the stomach because the effect of volume accelerates the emptying rate after proximal gastric vagotomy while the effects of concentration and type of acid remain unchanged.

    A 1-year old female spayed German Shepherd dog was evaluated for acute onset of dyspnea. Pyogranulomatous inflammation and green globoid structures were present on aspirates of the affected lung. Impression smears and histopathology confirmed pyogranulomatous pneumonia, with large amounts of lipid corresponding to the green structures noted cytologically, and identified poorly staining bacterial rods within lipid vacuoles. Special stains confirmed the presence of acid-fast bacterial rods, and polymerase chain reaction and DNA sequencing identified the organism as Mycobacterium fortuitum. M. fortuitum pneumonia is well described in humans and has previously been reported in 4 dogs and 1 cat. Lipid was a prominent cytologic and histologic feature, as is often described in humans and in the single feline case report. Additionally, this case highlights the variable cytologic appearance of lipid, as well as Mycobacterium spp, which are classically nonstaining with Wright-Giemsa. PMID:24788402

    Full Text Available Dogs and cats are the animals that owners most frequently seek assistance for potential poisonings, and these species are frequently involved with toxicoses due to ingestion of poisonous food. Feeding human foodstuff to pets may prove itself dangerous for their health, similarly to what is observed in Allium species toxicosis. Allium species toxicosis is reported worldwide in several animal species, and the toxic principles present in them causes the transformation of hemoglobin into methemoglobin, consequently resulting in hemolytic anemia with Heinz body formation. The aim of this review is to analyze the clinicopathologic aspects and therapeutic approach of this serious toxicosis of dogs and cats in order to give knowledge to veterinarians about Allium species toxicosis, and subsequently allow them to correctly diagnose this disease when facing it; and to educate pet owners to not feed their animals with Allium-containg food in order to better control this particular life-threatening toxicosis.

  8. Owned and unowned dog population estimation, dog management and dog bites to inform rabies prevention and response on Lombok Island, Indonesia.

    Directory of Open Access Journals (Sweden)

    Ana Mustiana

    Full Text Available Although Indonesia has been rabies-infected since at least the 1880s, some islands remain rabies-free, such as Lombok. However, due to its adjacency to rabies-infected islands such as Bali and Flores, there is considerable risk of a rabies incursion. As part of a rabies risk assessment project, surveys were conducted to estimate the size of the dog population and to describe dog management practices of households belonging to different ethnic groups. A photographic-recapture method was employed and the number of unowned dogs was estimated. A total of 400 dog owning households were interviewed, 300 at an urban site and 100 at a rural site. The majority of the interviewed households belonged to the Balinese ethnic group. Owned dogs were more likely male, and non-pedigree or local breed. These households kept their dogs either fully restricted, semi-free roaming or free-roaming but full restriction was reported only at the urban site. Dog bite cases were reported to be higher at the urban site, and commonly affected children/young adults to 20 years old and males. A higher number of unowned dogs was observed at the urban site than at the rural site. Data generated within these surveys can inform rabies risk assessment models to quantify the probability of rabies being released into Lombok and resulting in the infection of the local dog population. The information gained is critical for efforts to educate dog owners about rabies, as a component of preparedness to prevent the establishment of rabies should an incursion occur.

    Full Text Available Proteinuria, and renal tubular casts and epithelial cells in urine sediment, are commonly observed in both complicated and uncomplicated babesiosis, but do not necessarily reflect or predict renal failure. This study investigated the presence and degree of renal damage in canine babesiosis. Renal function and integrity were evaluated using serum urea and creatinine, serum electrolytes (sodium and potassium, fractional clearance of sodium (FcNa and potassium (FcK, urine enzyme activity of gamma-glutamyl transpeptidase and alkaline phosphatase, urine protein:creatinine ratio, and urinalysis. One control group (n =10 and 3 groups of babesiosis cases were studied: mild uncomplicated (n =10, severe uncomplicated (n = 11, and complicated (n = 9. All babesiosis groups showed well-concentrated urine. Mean serum urea was elevated in the severe and complicated groups, and was significantly different from the control group. There was no statistically significant difference between the groups for creatinine, although the complicated group had a mean value above the normal reference range. Hypokalaemia was uncommon in all the groups. Hyperkalaemia was present in only 2 dogs in the complicated group. Marginal hyponatraemia was present in a minority of dogs in all groups. The serumelectrolytes were not significantly different between groups. There was no overall elevation, nor any statistically significant difference in both the FcNa and FcK between the groups. Only 1 dog, in the complicated group, showed marked enzymuria. Proteinuria was a common finding and was significantly different between the severe and complicated groups and the control group. Some dogs in all groups had renal tubular epithelial cells in the urinary sediment, which increased in severity from the mild to the complicated groups and was significantly different from the control group. This study demonstrated that minimal renal damage occurs more often in canine babesiosis than significant

    The gastrointestinal absorption of plutonium in the beagle has been determined to be 0.066 +- 0.014% of the amount administered. This result is quite comparable with the results reported for the dog by other workers, and a factor of 3 smaller than that observed by us for mice. On the average, the retained plutonium was found to be almost equally divided between the liver and the skeleton

    2014-01-01

    Tracheal and airway collapse (bronchomalacia) are common causes of chronic cough in middle-aged to older dogs where weakening of cartilage within the respiratory system leads to narrowing of airways, coughing, wheezing, and other secondary effects. Successful treatment involves correct identification of the problem, recognition of concurrent problems, and appropriate medical therapy. Surgical and noninvasive treatment options are becoming readily available, and it is important to understand indications for such procedures. PMID:24268337

    Full Text Available Systemic arterial blood pressures were measured in 30 dogs with acute babesiosis, 10 each with mild uncomplicated, severe uncomplicated and complicated disease. Ten healthy dogs were used as controls. Hypotension was defined as more than 3 standard deviations below the control mean. Normal mean pressures (±SD were: systolic arterial pressure 151 (±11 mm Hg, diastolic arterial pressure 89 (±8 mm Hg and mean arterial pressure 107 (±10 mmHg. Hypotension was the most frequent abnormality, and increased strikingly in incidence as disease severity increased, with 5/10 dogs in the complicated group being hypotensive for systolic, diastolic and mean arterial pressures, compared with 2/10 in the severe uncomplicated group and 0/10 in the mild uncomplicated group. Systolic, diastolic and mean arterial pressures in the complicated group and severe uncomplicated group, and systolic pressure in the mild uncomplicated group, were significantly lower than in the controls. There were no significant relationships between arterial pressures and age, pulse rate, respiratory rate, temperature, mucous membrane colour or haematocrit. There was a significant negative correlation between arterial pressures and white cell and immature neutrophil counts. Arterial pressures differed significantly between dogs that were clinically collapsed and those that were not, but not between survivors and non-survivors. Pulse pressure (systolic - diastolic was low in 7/10 complicated, 1/10 mild uncomplicated, and 1/10 severe uncomplicated cases, and differed significantly between the complicated and control groups. The high incidence of hypotension in clinically severe babesiosis has important implications for therapy.

  17. The healing power of dogs: Cocoa's story.

    Animals bring a sense of "at homeness" and even normalcy to people who are hospitalized or live in health care facilities. Illnesses, separation from family, fear, loneliness, and even depression may be lessened for those who receive a therapy dog visit by providing a welcome change in routine and something to look forward to. Individuals are often more active and responsive during and after a visit. Just stroking and petting a dog requires the use of hands and arms, as well as the motions of stretching and turning. Dogs are also unconcerned with age or physical ability; they accept people as they are. This alone causes many to reach out and interact with dogs. Animals provide a focus for conversation and a common interest. As Cocoa's human partner can attest, a pet also makes it easier for strangers to talk. Cocoa is known by so many people at the facilities she visits that residents' family members often stop to talk with "Cocoa's mom" when they meet her in the community, asking questions about how Cocoa is doing. When Cocoa is no longer able to perform her services, many in her community will mourn. Cocoa's story, as well as the limited research literature, supports the positive physical and psychological effects of animals, but continued research on the effect of therapy animals on health outcomes is needed. As advocates for clients, nurses are in key positions to facilitate the inclusion of animals in clients' care. Although not for everyone, including those who react negatively to animals or who are allergic, pet therapy offers important possibilities for providing holistic care that extends not only to clients, but also to family members and staff, and to the pets themselves.

    Estimation of the quality of commercial diets is a topic of interest for the majority of dog owners. Recently, in a French consumer association magazine, an evaluation of eight dog commercial dry diets (from super-premium, basic-nutrition, private-label and economy brands) according to several nutritional criteria was published. The aims of the study were: (1) to evaluate the apparent digestibility of these diets; (2) to score these diets according to digestibility results; and (3) to compare these data with the scoring of the magazine. Six adult Beagle dogs were enrolled for the digestibility trials. Diets were scored according to energy, crude protein and crude fat (CF) apparent digestibility coefficients, digestible protein-to-energy ratios and ash content. Each of the five criteria was scored from 4 to 20 points. The ranges of crude protein, CF, crude fibre and ash content were 20·9-30·6 %, 6·8-19·7 %, 2·2-3·3 % and 4·6-9·7 % on a DM basis, respectively. The ranges of energy, crude protein and CF apparent digestibility coefficients were 72·6-87·7 %, 70·4-82·5 % and 76·1-95·4 %, respectively. The range of the protein-to-energy ratio was 10-14 digestible crude protein per MJ metabolisable energy. Little overlap in the scoring systems was found, but the private-label brand and economy brand diets presented the lowest scores in the two systems. These results showed that the evaluation of commercial diets should take into account multiple nutritional aspects. In particular, analytical and biological (digestibility) criteria should be considered as complementary in the evaluation of dry dog commercial diets. PMID:26101631

  20. A sacral lesion resembling osteochondrosis in the German Shepherd dog

    International Nuclear Information System (INIS)

    More than 30% (21 of 65) of German Shepherd dogs with clinical signs of cauda equina compression had radiographic and pathologic abnormalities compatible with osteochondrosis of the sacral endplate. Most of these dogs had a defect in the dorsal part of the sacral endplate and a detached bone fragment in the vertebral canal. Similar lesions were also found in growing and young adult dogs without clinical signs. The dogs with clinical signs of cauda equina compression also had severe degenerative disc disease with protrusion of the lumbosacral disc and compression of the cauda equina, suggesting that the signs of cauda equina compression more likely were related to the secondary degenerative changes (disc protrusions) rather than the primary disease. Clinically normal German Shepherds with sacral osteochondrosis usually were younger than 18 months, the dogs with cauda equina compression and sacral osteochondrosis older than 18 months (mean age 4.8 years). On the average, these dogs were two years younger as compared to dogs with cauda equina compression without sacral osteochondrosis. Male dogs are more often affected than females (5:1). There is a breed predisposition: in dogs other than German Shepherds, osteochondrosis of the sacral endplate seems to be extremely rare

  1. Lumbar myelography in 79 dogs, using different puncture sites

    International Nuclear Information System (INIS)

    Lumbar myelography was performed in 79 dogs either before spinal surgery or as part of an investigation of neurological disease. In small dogs the site of the puncture was between L1 and L5, avoiding the lumbosacral intumescence, whereas in large dogs the site was between T13 and L2. It was found that a lumbar puncture cranial to the lumbar intumescence was easier and caused no problems. The lumbar puncture was unsuccessful in three obese dogs. In 72 per cent of the cases the myelogram revealed a lesion, and the main cause of a non-diagnostic myelogram was epidural leakage

  2. Nonweightbearing lameness secondary to synovial sarcoma in a young dog

    International Nuclear Information System (INIS)

    Synovial sarcoma was diagnosed in the right carpus of a 2 1/2-year-old mixed-breed dog. The dog had developed a right forelimb lameness before one year of age. The lameness was progressive for nearly 2 years, resulting in severe disuse atrophy of the right forelimb musculature and pronounced osteopenia. A definitive diagnosis was not made until the dog was referred after 2 years of conservative treatment was ineffectual. Right forelimb amputation was done and the dog survived an additional 15 months. The protracted clinical course before definitive diagnosis underscores the need for aggressive pursuit of a diagnosis when conservative treatment of a lameness is not efficacious

    Full Text Available Ehrlichia canis is a major pathogen in dogs throughout Africa, yet it has not been reported in Namibia. The aim of this study was to determine the seroprevalence of canine ehrlichiosis in central Namibia using the ImmunoComb assay (Biogal, Galed Laboratories. The study included 76 dogs that presented to the Rhino Park Veterinary Clinic in the north-western suburb of Khomasdal, Windhoek, Namibia, as well as 30 stray dogs from the Windhoek branch of the Society for the Prevention of Cruelty to Animals. Of the 106 dogs tested, 53.8% were seropositive at titres > 1:80. Dogs that presented with symptoms of E. canis infection had a significantly higher seroprevalence (86.6% compared with apparently healthy dogs (41.6% (P = 0.00. Location of habitation was significant (P < 0.017, with a high percentage of dogs exposed to E. canis living in the northern or north-western part of Windhoek. As the first study to serologically establish E. canis as a major pathogen in dogs in central Namibia, it is notable that the highest proportion of seropositive dogs came from low-income areas. Further investigation is necessary to describe the ecology of this important tick-borne pathogen of companion animals in Namibia.

  4. Dogs' Eavesdropping from people's reactions in third party interactions.

    Full Text Available Eavesdropping involves the acquisition of information from third-party interactions, and can serve to indirectly attribute reputation to individuals. There is evidence on eavesdropping in dogs, indicating that they can develop a preference for people based on their cooperativeness towards others. In this study, we tested dogs' eavesdropping abilities one step further. In a first experiment, dogs could choose between cooperative demonstrators (the donors who always gave food to an approaching third person (the beggar; here, the only difference between donors was whether they received positive or negative reactions from the beggar (through verbal and gestural means. Results showed that dogs preferentially approached the donor who had received positive reactions from the beggar. By contrast, two different conditions showed that neither the beggar's body gestures nor the verbal component of the interaction on their own were sufficient to affect the dogs' preferences. We also ran two further experiments to test for the possibility of dogs' choices being driven by local enhancement. When the donors switched places before the choice, dogs chose at random. Similarly, in a nonsocial condition in which donors were replaced by platforms, subjects chose at chance levels. We conclude that dogs' nonrandom choices in the present protocol relied on the simultaneous presence of multiple cues, such as the place where donors stood and several features of the beggar's behavior (gestural and verbal reactions, and eating behavior. Nonetheless, we did not find conclusive evidence that dogs discriminated the donors by their physical features, which is a prerequisite of reputation attribution.

    International Nuclear Information System (INIS)

    The gastroduodenal mucosa in dogs experimentally treated with nimesulide, monophenylbutazone and meloxicam was evaluated. There were four groups with eight dogs in each. Groups one, two and three were given nimesulide, monophenylbutazone and meloxicam, respectively, during 21 days and group four was used as control. All animals were evaluated by gastroduodenoscopy before the study and on the 10th and 21st days. The dogs did not show any clinical or laboratorial changes during the study. The endoscopic evaluation of gastroduodenal mucosa showed only low degree lesions. These anti-inflammatory drugs showed to be safe for the gastrointestinal tract in healthy dogs

    Hemangiosarcomas (HSAs) are aggressive tumors with a high rate of metastasis. Clinical stage has been considered a negative prognostic factor for survival. The study authors hypothesized that the median survival time (MST) of dogs with metastatic (stage III) HSA treated with a vincristine, doxorubicin, and cyclophosphamide (VAC) chemotherapy protocol would not be different than those with stage I/II HSA. Sixty-seven dogs with HSA in different anatomic locations were evaluated retrospectively. All dogs received the VAC protocol as an adjuvant to surgery (n = 50), neoadjuvant (n = 3), or as the sole treatment modality (n = 14). There was no significant difference (P = 0.97) between the MST of dogs with stage III and stage I/II HSA. For dogs presenting with splenic HSA alone, there was no significant difference between the MST of dogs with stage III and stage I/II disease (P = 0.12). The overall response rate (complete response [CR] and partial response [PR]) was 86%). No unacceptable toxicities were observed. Dogs with stage III HSA treated with the VAC protocol have a similar prognosis to dogs with stage I/II HSA. Dogs with HSA and evidence of metastases at the time of diagnosis should not be denied treatment. PMID:24051260

  8. Toxicity of inhaled 91YCl3 in Beagle dogs. XVIII

    International Nuclear Information System (INIS)

    The metabolism, dosimetry, and biological effects of inhaled 91YCl3 were studied in Beagle dogs. Forty-two dogs with initial 91Y body burdens from 14 to 1300 μCi/kg (0.52-48 MBq/kg) body weight and 12 control dogs were observed during their life spans. Four additional dogs with a mean initial body burden of 180 μCi 91Y/kg (6.7 MBq/kg) body weight were placed in a sacrifice study. All 46 of the exposed dogs and all 12 of the control dogs have died. Dogs with the highest initial body burdens died with bone marrow damage and pancytopenia. Of the dogs dying of late-occurring effects, three died with nasal cavity carcinomas, three died with pulmonary carcinomas, and one died with hepatic hemangiosarcoma. These cancers all appeared to be related to radiation injury. Control dogs died of miscellaneous neoplastic and chronic diseases. 1 reference, 1 figure, 3 tables

    Cooperation is thought to be highly dependent on tolerance. For example, it has been suggested that dog-human cooperation has been enabled by selecting dogs for increased tolerance and reduced aggression during the course of domestication ('emotional reactivity hypothesis'). However, based on observations of social interactions among members of captive packs, a few dog-wolf comparisons found contradictory results. In this study, we compared intraspecies aggression and tolerance of dogs and wolves raised and kept under identical conditions by investigating their agonistic behaviours and cofeeding during pair-wise food competition tests, a situation that has been directly linked to cooperation. We found that in wolves, dominant and subordinate members of the dyads monopolized the food and showed agonistic behaviours to a similar extent, whereas in dogs these behaviours were privileges of the high-ranking individuals. The fact that subordinate dogs rarely challenged their higher-ranking partners suggests a steeper dominance hierarchy in dogs than in wolves. Finally, wolves as well as dogs showed only rare and weak aggression towards each other. Therefore, we suggest that wolves are sufficiently tolerant to enable wolf-wolf cooperation, which in turn might have been the basis for the evolution of dog-human cooperation (canine cooperation hypothesis).

    It was reported that the tiron had good therapeutic effects on small animals with acute uranium intoxication. The tiron's therapeutic effects as a first aid on large animals (38 dogs) with acute uranium poisoning are reported in this paper. Indices reflecting its effect were as follows: excretion rate of uranium from the dogs, several appropriate biochemical tests, clinical manifestations, histo-pathological changes of kidney and liver, and also the mortality of dogs. The results showed that the tiron or a combination of tiron and NaHCO3 has a good therapeutic effect as a first aid on the dogs receiving lethal dose of uranyl nitrate

    Canine distemper virus (CDV) causes a major disease of domestic dogs that develops as a serious systemic infection in unvaccinated or improperly vaccinated dogs. Domesticated dogs are the main reservoir of CDV, a multihost pathogen. This virus of the genus Morbillivirus in the family Paramyxoviridae occurs in other carnivorous species including all members of the Canidae and Mustelidae families and in some members of the Procyonidae, Hyaenidae, Ursidae, and Viverridae families. Canine distemper also has been reported in the Felidae family and marine mammals. The spread and incidences of CDV epidemics in dogs and wildlife here and worldwide are increasing. PMID:22041204

    Torad, Faisal A; Hassan, Elham A

    2013-01-01

    Salivary mucocele is one of the causes of submandibular swelling in dogs and is due to a collection of mucoid saliva that has leaked from a damaged salivary gland. The purpose of this case series report was to describe the clinical and ultrasonographic characteristics of confirmed salivary mucoceles in 13 dogs admitted to the Faculty of Veterinary Medicine at Cairo University. The final diagnosis of salivary mucocele was based on aspirate cytology for all dogs and additional surgical excision for seven dogs. For dogs admitted from 2 weeks to 1 month from the onset of clinical signs, the cervical mucocele appeared as a round echogenic structure with a large volume of central anechoic content. The wall was a clearly identified hyperechoic structure surrounding the gland. For dogs admitted between 1 to 2 months from the onset of clinical signs, the volume of anechoic material appeared less than that seen in the acute cases. The overall appearance of the salivary mucocele was heterogenous. For dogs admitted after 2 months from the onset of clinical signs, the salivary mucocele appeared grainy or mottled, with a heterogenous appearance and a further decrease in anechoic content. For one dog that presented after 3 months from the onset of clinical signs, the salivary mucocele was hard on palpation and appeared hyperechoic with distal acoustic shadowing. Findings from this study indicated that ultrasonographic characteristics of salivary mucoceles in dogs vary depending on the chronological stage of the disease. PMID:23442204

Moreover, several canine intestinal protozoan parasites are zoonotic and are considered important to public health. This study investigates the level of intestinal protozoan parasites in stray dogs, in Kerman city, Iran. Approach: Determination of the prevalence of infections was based on faecal examination. Stool samples (n = 98 collected from dogs of different ages and gender were analyzed using five techniques, i.e., centrifugal flotation in sucrose solution, centrifugal flotation in 33% Zinc solphate solution, Ziehl-Neelsen staining, trichrome staining and iodine staining. Results: The overall prevalence of parasitism was 13 (13.26% dogs. The parasites most frequently detected were: Giardia spp. (7.14%, Isospora spp. (5.1% and Cryptosporidium spp. (4.08%. Single parasitic infection was present in 11 (11.22% dogs. There was no significant difference in the prevalence between male (13.3% and female (13.2% dogs (p>0.05. There was significantly (pConclusion/Recommendations: The results of this research showed that stray dogs are reservoirs for zoonotic intestinal protozoan parasites and should be considered important to public health. So that, it is imperative for human to avoid faecal contamination in streets, public gardens and parks. Also stray dogs should be euthanized in dog population control program in Iran.

    2016-04-01

    Full Text Available Ectrodactyly is the term used to designate cases in which soft and bone tissue separation within the distal region of the thoracic limbs is present. It is observed in particular below the metacarpal bones and extending to the radius and ulna. In addition, it can often be associated with ipsilateral elbow luxation. We describe a case of ectrodactyly in a 3-month-old mongrel dog, where bone and soft tissue separation occurred between the third and fourth digits, extending proximally to the carpal region. We identified shortening of the ulna without elbow luxation. The dog was subjected to a surgical procedure comprising bone and soft tissue reconstruction and ulnar diaphyseal osteotomy, which was fixed using a Steinmann pin in the intramedullary canal, maintaining a distance of 1 cm between the two ulnar fragments. Two distal phalanges were removed because it was not possible to reposition them anatomically in the limb. The dog walked with mild lameness nine months after surgery.

    A case of presumed primary muscular lymphoma in an 8-year-old, intact, male Newfoundland dog is reported. The dog was presented for evaluation of an infiltrating ventral cervical mass, respiratory distress, and anorexia of 1-month duration. Fine-needle aspiration of the mass revealed anaplastic large cell lymphoma. Despite chemotherapy, health status declined and the animal was euthanized a few weeks later. At necropsy, the mass infiltrated the cervical muscles and extended ventrally to the left forelimb and cranially to the tongue and laryngeal musculature. Other muscles were infiltrated by the same neoplasm (diaphragm and intercostal, abdominal, and gluteal muscles) indicating a probable multicentric origin. Histological examination confirmed the diagnosis of anaplastic large cell lymphoma, which showed a strong muscular tropism. Immunohistochemical staining revealed neoplastic cell reactivity for cluster of differentiation 3 (CD3) and Ki-67 antigens (70% and 90%, respectively). The neoplastic cells were negative for CD79a. The presumed histological diagnosis in this dog was primary muscular anaplastic large T-cell lymphoma. PMID:18987239

    To investigate canine kobuvirus (CaKoV) infection, fecal samples (n = 59) were collected from dogs with or without diarrhea (n = 21 and 38, respectively) in the Republic of Korea (ROK) in 2012. CaKoV infection was detected in four diarrheic samples (19.0 %) and five non-diarrheic samples (13.2 %). All CaKoV-positive dogs with diarrhea were found to be infected in mixed infections with canine distemper virus and canine parvovirus or canine adenovirus. There was no significant difference in the prevalence of CaKoV in dogs with and without diarrhea. By phylogenetic analysis based on partial 3D genes and complete genome sequences, the Korean isolates were found to be closely related to each other regardless of whether they were associated with diarrhea, and to the canine kobuviruses identified in the USA and UK. This study supports the conclusion that CaKoVs from different countries are not restricted geographically and belong to a single lineage. PMID:24906525

It remains unclear whether oversized ventricles represent a normal variant or a pathological condition in brachycephalic dogs. There is a distinct relationship between white matter and grey matter in the cerebrum of all eutherian mammals. The aim of this study was to determine if this physiological proportion between white matter and grey matter of the forebrain still exists in brachycephalic dogs with oversized ventricles. The relative cerebral grey matter, white matter and cerebrospinal fluid volume in dogs were determined based on magnetic-resonance-imaging datasets using graphical software. In an analysis of covariance (ANCOVA using body mass as the covariate, the adjusted means of the brain tissue volumes of two groups of dogs were compared. Group 1 included 37 mesaticephalic dogs of different sizes with no apparent changes in brain morphology, and subjectively normal ventricle size. Group 2 included 35 brachycephalic dogs in which subjectively enlarged cerebral ventricles were noted as an incidental finding in their magnetic-resonance-imaging examination. Whereas no significant different adjusted means of the grey matter could be determined, the group of brachycephalic dogs had significantly larger adjusted means of lateral cerebral ventricles and significantly less adjusted means of relative white matter volume. This indicates that brachycephalic dogs with subjective ventriculomegaly have less white matter, as expected based on their body weight and cerebral volume. Our study suggests that ventriculomegaly in brachycephalic dogs is not a normal variant of ventricular volume. Based on the changes in the relative proportion of WM and CSF volume, and the unchanged GM proportions in dogs with ventriculomegaly, we rather suggest that distension of the lateral ventricles might be the underlying cause

    High altitude mountaineering is a dangerous endeavor due to the hypoxic hypobaric environment, extreme weather, and technical skills required. One of the seven summits, Aconcagua (6962 m) is the highest mountain outside of Asia. Its most popular route is nontechnical, attracting >3000 mountaineers annually. Utilizing data from the Servicio Médico Aconcagua (park medical service), we performed a retrospective descriptive analysis with the primary objective of deriving a fatality rate on Aconcagua from 2001 to 2012. The fatality rate on Aconcagua was then compared to other popular mountains. For climbers who died, we report all available demographic data, mechanisms of death, and circumstances surrounding the death. Between 2001 and 2012, 42,731 mountaineers attempted to summit Aconcagua. There were 33 fatalities. The fatality rate was 0.77 per 1000, or 0.077%. The fatality rate on Aconcagua is lower than that on Everest or Denali but higher than that on Rainier. PMID:24028641

  12. Influence of mountains on Arctic tropospheric ozone

    Seabrook, Jeffrey; Whiteway, James

    2016-02-01

    Tropospheric ozone was measured above Ellesmere Island in the Canadian Arctic during spring of 2008 using a differential absorption lidar. The observations were carried out at Eureka Weather Station, which is located between various mountain ranges. Analysis of the observations revealed that mountains had a significant effect on the vertical distribution of ozone. Ozone depletion events were observed when air that had spent significant time near to the frozen surface of the Arctic Ocean reached Eureka. This air arrived at Eureka by flowing over the surrounding mountains. Surface level ozone depletions were not observed during periods when mountains blocked the flow of air from over the sea ice. In the case of blocking there was an enhancement in the amount of ozone near the surface as air from the midtroposphere descended in the lee of the mountains. Three case studies from spring of 2008 are described.

  13. An Infectious Disease and Mortality Survey in a Population of Free-Ranging African Wild Dogs and Sympatric Domestic Dogs

    Full Text Available Disease can cause declines in wildlife populations and significantly threaten their survival. Recent expansion of human and domestic animal populations has made wildlife more susceptible to transmission of pathogens from domestic animal hosts. We conducted a pathogen surveillance and mortality survey for the population of African wild dogs (Lycaon pictus in KwaZulu-Natal (KZN, South Africa, from January 2006–February 2007. Samples were obtained from 24 wild dogs for canine distemper virus (CDV and canine parvovirus (CPV serological testing. Data were collected on the presence of CDV, CPV, and rabies virus in the KZN domestic dog (Canis familiaris population from 2004–06. The presence of these pathogens was confirmed in domestic dogs throughout KZN. Wild dogs exhibited 0% and 4.2% prevalence for CDV and CPV antibodies, respectively. In 2006 the largest wild dog pack in KZN was reduced from 26 individuals to a single animal; disease due to rabies virus was considered the most probable cause. This study provides evidence that CDV, CPV and rabies are potential threats to African wild dog conservation in KZN. The most economical and practical way to protect wild dogs from canine pathogens may be via vaccination of sympatric domestic dogs; however, such programmes are currently limited.

  14. Using the incidence and impact of behavioural conditions in guide dogs to investigate patterns in undesirable behaviour in dogs.

    2016-01-01

    The domestic dog is one of our most popular companions and longest relationships, occupying different roles, from pet to working guide dog for the blind. As dogs age different behavioural issues occur and in some cases dogs may be relinquished or removed from their working service. Here we analyse a dataset on working guide dogs that were removed from their service between 1994 and 2013. We use the withdrawal reasons as a proxy for the manifestation of undesirable behaviour. More than 7,500 dogs were in the dataset used, 83% of which were retired (due to old age) and 17% were withdrawn for behavioural issues. We found that the main reasons for behaviour withdrawal were environmental anxiety, training, and fear/aggression. Breed and sex had an effect on the odds of dogs being withdrawn under the different reasons. The age at withdrawal for the different withdrawal reasons suggested that dogs were more likely to develop fear/aggression related issues early on, whilst issues related to training could develop at almost any age. We found no evidence for heterosis effecting behaviour. We believe that this work is relevant to the pet dog population and had implications for understanding ageing and genetic influences on behaviour. PMID:27075868

    2015-06-01

    Full Text Available Aim: The present research work was undertaken to study the diagnostic importance of hematobiochemical changes in naturally occurring ehrlichiosis in dogs of Anand region, Gujarat irrespective of their age, breed, and sex. Materials and Methods: Blood samples from a total of 29 dogs of Anand region of Gujarat state were screened for detection of anti-Ehrlichia canis antibodies using Immunocomb® rapid diagnostic kit (Biogal Galed Laboratories, Israel and subjected to estimation of hematobiochemical parameters by auto hematology analyzers at College of Veterinary Science and Animal Husbandry, Anand. Statistical analysis, interpretation and comparison of hematobiochemical changes with scientific literature was carried out in order to understand the pathophysiology of the disease. Results: Of 29 dogs, 18 were positive for naturally occurring ehrlichiosis based on the presence of anti-E. canis antibodies while 11 were negative. Haematology evinced that the mean values of hemoglobin, total erythrocyte counts, platelet count and packed cell volume in dogs with ehrlichiosis decreased significantly (p0.05 difference was observed in values of monocytes in dogs with ehrlichiosis and healthy dogs. Among various red blood cells indices, the mean values of mean corpuscular hemoglobin concentration increased significantly (p<0.01 in dogs with ehrlichiosis in comparison to healthy dogs. Serum biochemistry revealed significant (p<0.01 increase in serum glutamic pyruvic transaminase, serum glutamic oxaloacetic transaminase and creatinine levels as well as decrease in total protein levels in dogs with ehrlichiosis as compared to healthy dogs. Conclusion: Clinical importance of hematobiochemical changes in 18 natural cases of ehrlichiosis in dogs of Anand region, Gujarat irrespective of their age, breed and sex is discussed, which would aid new insights in diagnosis and therapeutic management.

  16. Humans process dog and human facial affect in similar ways.

    Directory of Open Access Journals (Sweden)

    Annett Schirmer

    Full Text Available Humans share aspects of their facial affect with other species such as dogs. Here we asked whether untrained human observers with and without dog experience are sensitive to these aspects and recognize dog affect with better-than-chance accuracy. Additionally, we explored similarities in the way observers process dog and human expressions. The stimulus material comprised naturalistic facial expressions of pet dogs and human infants obtained through positive (i.e., play and negative (i.e., social isolation provocation. Affect recognition was assessed explicitly in a rating task using full face images and images cropped to reveal the eye region only. Additionally, affect recognition was assessed implicitly in a lexical decision task using full faces as primes and emotional words and pseudowords as targets. We found that untrained human observers rated full face dog expressions from the positive and negative condition more accurately than would be expected by chance. Although dog experience was unnecessary for this effect, it significantly facilitated performance. Additionally, we observed a range of similarities between human and dog face processing. First, the facial expressions of both species facilitated lexical decisions to affectively congruous target words suggesting that their processing was equally automatic. Second, both dog and human negative expressions were recognized from both full and cropped faces. Third, female observers were more sensitive to affective information than were male observers and this difference was comparable for dog and human expressions. Together, these results extend existing work on cross-species similarities in facial emotions and provide evidence that these similarities are naturally exploited when humans interact with dogs.

    Thirty-five or forty centuries ago, there were probably Egyptian experts who argued that they could safeguard the tombs of the pharaohs for 10,000 or a million years. Six centuries ago, there were probably Italian experts who believed that they could secure their Renaissance art treasures. Neither the Egyptians nor the Italians succeeded completely in their efforts. Today's experts, working on permanent nuclear waste disposal, face no easier a task. To understand some of the most difficult problems of expert judgment regarding nuclear repositories, these remarks address, 10 problematic judgments of scientists about the proposed Yucca Mountain permanent nuclear repository for spent fuel and high-level nuclear waste; argue that legal constraints imposed by the US government exacerbate these problems of expert scientific judgment; and conclude that, for any permanent repository program to succeed, nations ought to avoid problems (in expert scientific judgment and in the law) that have dogged US repository efforts.

    Full Text Available Aim: This serological survey was undertaken to estimate the prevalence of Toxoplasma gondii in two populations of dogs (stray and owned dogs in Grenada. Dogs get infected with oocysts voided from cats, definitive hosts of T. gondii. In dogs, T. gondii causes subclinical to clinical disease. Earlier studies conducted in Grenada on a small population of owned dogs showed evidence of exposure to T. gondii. Materials and Methods: Antibodies to T. gondii were determined in serum samples from 625 dogs (368 stray and 257 owned dogs from around all six parishes in Grenada, West Indies, using an indirect enzyme linked immunosorbent assay. Results: Antibodies to T. gondii were found in 123 (33.4%; 95% confidence interval [CI]: 28.58-38.22% of stray dogs and in 64 (25%; 95% CI: 19.71-30.29% of the owned dogs. Seropositivity was higher in stray dogs than in pet dogs (p=0.026. Whereas, there was no sex predisposition to seropositivity in owned dogs (p=1.0, female stray dogs showed a higher prevalence than male stray dogs (p=0.04. Conclusion: These results support previous findings that T. gondii is prevalent in Grenada. In this study, overall seropositivity for T. gondii in dogs in Grenada is lower than noted in 2008, but is still higher in stray dogs than in owned dogs.

    OBJECTIVE To compare expression, activity, and fecal concentration of intestinal alkaline phosphatase (IAP) between healthy dogs and dogs with chronic enteropathy (CE). ANIMALS 9 healthy university-owned Beagles and 109 healthy client-owned dogs (controls) and 28 dogs with CE (cases). PROCEDURES Cases were defined as dogs with persistent (> 3 weeks) gastrointestinal signs that failed to respond to antimicrobials and anti-inflammatory doses of prednisolone or dietary trials, did not have mechanical gastrointestinal abnormalities as determined by abdominal radiography and ultrasonography, and had a diagnosis of lymphoplasmacytic enteritis or eosinophilic gastroenteritis on histologic examination of biopsy specimens. Duodenal and colonic mucosa biopsy specimens were obtained from the 9 university-owned Beagles and all cases for histologic examination and determination of IAP expression (by real-time quantitative PCR assay) and activity (by enzyme histochemical analysis). Fecal samples were obtained from all dogs for determination of fecal IAP concentration by a quantitative enzyme reaction assay. RESULTS For dogs evaluated, IAP expression and activity were localized at the luminal side of epithelial cells in the mucosa and intestinal crypts, although both were greater in the duodenum than in the colon. Active IAP was detected in the feces of all dogs. Intestinal alkaline phosphatase expression and activity were lower for cases than for controls, and fecal IAP concentration for dogs with moderate and severe CE was lower than that for dogs with mild CE. CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that dogs with CE had impaired IAP expression and activity. Additional research is necessary to elucidate the role of IAP in the pathogenesis of CE. PMID:27347825

    A total of 628 Escherichia coli isolates recovered from 877 intestinal samples of stray pet dogs (n = 565) and hospitalized pet dogs (n = 312) in Korea were analyzed for resistance to 15 antimicrobial agents. Most common resistance observed in E. coli isolated from both groups of dogs was to tetracycline (52.4-53.6%), streptomycin (35.8-41.7%), ampicillin (32.9-47.1%), nalidixic acid (21.6-37.4%), and trimethoprim/sulfamethoxazole (19.7-36.4%). Resistance to chloramphenicol, gentamicin, and ciprofloxacin was observed in 19.4% (17.1-24.3%), 18% (16.1-21.8%), and 16.1% (13.5-21.4%) of the isolates, respectively. No E. coli isolated from hospitalized dogs showed resistance to imipenem and cefepime, whereas three (0.7%) isolates from stray dogs were resistant to cefepime. Some of the isolates from both groups showed resistance to cefotaxime (2.4-3.9%) and amikacin (0.5-1.5%). In general, the frequency of resistance tended to be higher in isolates from hospitalized dogs than isolates from stray dogs against most antimicrobials tested. Around 39% (162/422) and 27% (55/206) of E. coli isolates from stray dogs and hospitalized dogs were susceptible to all antimicrobials tested, respectively. Multiresistance (> or = 3 subclasses of antimicrobials) was observed in 32% and 48% of E. coli isolates from stray dogs and hospitalized dogs, respectively. More attention should be paid to the use of antimicrobials and the occurrence of antimicrobial resistance in companion animals. PMID:20192822

  3. Ultrasonographic findings in 14 dogs with ectopic ureter

    International Nuclear Information System (INIS)

    To evaluate ultrasonography as an alternative to contrast radiographyfor diagnosis of ectopic ureter in dogs, ultrasonography of the urinary tract was performed prospectively in a series of urinary incontinent dogs anesthetized for contrast radiography, Fourteen dogs had ectopic ureter based ore surgical, necropsy or unequivocal contrast radiographic findings, There were eight females and six males of a variety of breeds; five were Labrador retrievers, Mean (range) age at the time ofdiagnosis was 1.2 (0.2-4) years for females and 3.5 (0.3-5) for males(p < 0.05). Ectopic ureters were unilateral in five dogs (2 left; 3 right) find bilateral in nine dogs. Both ultrasound images and contrastradiographs were positive for 21 (91%) ectopic ureters; the same two ectopic ureters were not defected using either modality, The termination of each of the five normal ureters was visible on ultrasound images; two (40%) were visible on radiographs, Other ultrasonographic findings included dilatation of the ectopic ureter and/or ipsilateral renal pelvis ill ten (43%) instances, evidence of pyelonephritis in two dogs(with enlargement of the contralateral kidney in one dog), and urethral diverticuli in one dog, Ultrasonography is a practical diagnostic Best for ectopic ureter in clogs. In this series these was close correlation between the ultrasonographic and contrast radiographic findings for each ectopic meter, but ultrasonography enabled more accurate determination of normal ureteral anatomy

  4. Simultaneous double-contrast cystography and cystometry in dogs

    International Nuclear Information System (INIS)

    Double-contrast cystograms and cystometrograms were performed simultaneously in each of six male and six female dogs with normal urinalyses. The dogs were sedated with oxymorphone and acepromazine. Detrusor reflex occurred in 11 of 12 dogs. After bladder infusion of 0.88 ml/kg of positive-contrast medium, there was mucosal irregularity in eight of 12 dogs and bladder shape distortion in 12 of 12 dogs. Bladder distortion decreased with progressive infusion of CO2, and mucosal irregularity was eliminated after infusion of 50–100 ml CO2. The bladder neck in all dogs was initially located within the pelvic canal. In ten of 12 dogs, the bladder neck was cranially displaced when the bladder was fully distended. Bladder wall thickness was approximately 1 mm circumferentially at all degrees of distention. There was no discernible difference between bladder shape prior to and at initiation of contraction. It was concluded that radiographic determination of a normal urinary bladder can be made without complete bladder distention and that cystograms and cystometrograms can be routinely performed simultaneously in dogs in which both procedures are required

    2015-11-01

    Dogs drink by lapping because they have incomplete cheeks and cannot suck fluids into the mouth. When lapping, a dog's tongue pulls a liquid column from a bath, which is then swallowed, suggesting that the hydrodynamics of column formation are critical to understanding how dogs drink. We measured the kinematics of lapping from nineteen dogs and used the results to generate a physical model of the tongue's interaction with the air-fluid interface. These experiments with an accelerating rod help to explain how dogs exploit the fluid dynamics of the generated column. The results suggest that effects of acceleration govern lapping frequency, and that dogs curl the tongue ventrally (backwards) and time their bite on the column to increase fluid intake per lap. Comparing lapping in dogs and cats reveals that though they both lap with the same frequency scaling with respect to body mass and have similar morphology, these carnivores lap in different physical regimes: a high-acceleration regime for dogs and a low-acceleration regime for cats.

In the light of the zoonotic potential of Giardia infection, a total of 248 companion animals (167 dogs and 81 cats were examined for giardiasis in the same urban area. The overall rates of infection in dogs and cats were 14.4% (24/167 and 22.2 % (18/81, respectively. Significantly (p<0.05, p<0.01 higher infection rates were found in stray (18.7% and farm (36.4% dogs than in household pets (7.4%. Furthermore, the rate of infection was significantly (p<0.01 higher in domestic cats than in household dogs (22.2%vs. 7.4%. The owners and all 16 of their family members of five out of the six household pet dogs excreting Giardia were Giardia-negative, while both the owner of one dog and the only other family member were Giardia-positive. The data demonstrate that potential animal reservoirs (dogs and cats exist in urban Serbia and underline the possibility of transmission between dog and man in close contact, thus having important implications for the epidemiology of giardiasis in urban areas.

    Occasionally, a dog-bite is complicated by a systemic overwhelming infection. We report four consecutive patients who were admitted to our intensive care unit because of sepsis syndrome following dog-bites. The history of these patients did not reveal any immunocompromising conditions. Capnocytophag

  13. European consensus statement on leptospirosis in dogs and cats

    Science.gov (United States)

    Leptospirosis is a zoonotic disease of worldwide distribution affecting most mammalian species. Clinical leptospirosis is common in dogs but seems to be rare in cats. Both dogs and cats however, can shed leptospires in the urine. This is problematic as it can lead to exposure of humans. The control ...

  14. Diarrhea associated with myenteric ganglionitis in a dog

    International Nuclear Information System (INIS)

    Diarrhea in a Border Terrier was associated with inflammatory lesions of the myenteric plexus. This lesion has been documented rarely in dogs. It is speculated that the myenteric plexus lesions were responsible for an autonomic nervous system dysfunction, which resulted in extreme intestinal hypermotility and subsequent diarrhea. Suggested tests for dogs suspected to have autonomic dysfunction are given

    While the idea of using a dog in the classroom at first seems unorthodox, the history of using animals in therapeutic settings is extensive. The first documented use of animals in a therapeutic setting was in a mental institution in England in 1792 (Levinson, 1969). In North America, dogs were first used in therapy in 1919 at St. Elizabeth's…

    Full Text Available Abstract Background Estimates of demographic parameters, such as age-specific survival and fecundity, age at first pregnancy and litter size, are required for roaming dogs (i.e. dogs that are neither confined nor restricted to assess the likely effect of proposed methods of population control. Data resulting from individual identification of dogs spayed as part of an Animal Birth Control (ABC programme in Jaipur, India, are used to derive such parameters for the roaming dog population of that city. Results The percentage of females becoming pregnant in any given year was estimated by inspection of over 25,000 females caught for spaying from 1995 to 2006. The point estimate is 47.5% with a 95% confidence interval from 44% to 51%. Adult annual survival of spayed females was estimated by recapture of 62 spayed females from 2002 to 2006. The point estimate is 0.70 (95% confidence interval from 0.62 to 0.78, corresponding to an expected total lifespan of 3.8 years for a spayed female at one year old. Conclusion Recording the pregnancy status of dogs collected for spaying and individual marking of dogs released following spaying can provide estimates of some of the demographic parameters essential for predicting the future effectiveness of an ABC programme. Further, we suggest that recording the number and location of spayed and unspayed dogs encountered by the catching teams could be the most effective way to monitor the size and composition of the roaming dog population.

  17. A review of the usefulness of myelography in 50 dogs

    International Nuclear Information System (INIS)

    Fifty dogs showing clinical signs of spinal disease were investigated by myelography, using iopamidol. In 27 cases the technique was considered worthwhile. Of the 19 dogs not subjected to surgery or euthanasia as a result of the findings, three suffered seizures during recovery from anaesthesia, eight deteriorated in neurological condition and one suffered permanent respiratory arrest as a result of extensive subarachnoid haemorrhage

    To achieve a clearer understanding of the mechanisms responsible for neutrophil dysfunction recently described in dogs with chronic renal failure (CRF), the plasma concentrations of free p-cresol in healthy dogs (n = 20) and those with CRF (n = 20) were compared. The degree of correlation was determined between plasma levels of p-cresol and markers of oxidative stress and function of neutrophils in these dogs. The effect of this compound on oxidative metabolism and apoptosis was assessed in neutrophils isolated from 16 healthy dogs incubated in RPMI 1640 supplemented with p-cresol (0.405 mg/L) and compared with medium supplemented with uremic plasma (50%). To achieve this, the plasma concentration of p-cresol was quantified by liquid phase high-performance liquid chromatography. The neutrophil oxidative metabolism was determined using the probes hydroethidine and 2',7'-dichlorofluorescein diacetate and apoptosis was measured using Annexin V-PE by capillary flow cytometry. Compared with the healthy dogs, uremic dogs presented higher concentrations of free p-cresol, greater oxidative stress, and neutrophils primed for accelerated apoptosis. The free p-cresol induced in neutrophils from healthy dogs increased apoptosis and decreased reactive oxygen species production. We conclude that the health status presented during uremia concomitant with the increase in plasma free p-cresol can contribute to the presence of immunosuppression in dogs with CRF. PMID:26496142

    This paper reports results from a "natural experiment" taking place in China on the impact of dogs on owners' health. Previous Western research has reported modest health benefits, but results have remained controversial. In China pets were banned in urban areas until 1992. Since then dog ownership has grown quite rapidly in the major cities,…
