The study was conducted on twenty dogs, brought to the TVCC with the history of hind limb(s) lameness, with the objective to screen susceptible breeds of dogs for hip dysplasia, and to record its clinical and radiographic signs. Anamnesis, clinical signs, RT, HR and RR were recorded. Physical examinations viz. Ortolani test, Barden test, Barlow sign were done. Radiographic examination of hip joint was done to record Norberg angle, per cent femoral head coverage, distraction index (DI), femoral head neck and shaft angle and different morphological changes. Prevalence of hip dysplasia at the surgical unit of TVCC was 1.09% (14/1284). Out of 20 cases screened for hip dysplasia, 14 dogs were dysplastic and 6 dogs were non-dysplastic. Labrador retriever and German shepherd were at higher risk to hip dysplasia. Male dogs (9) were more affected than female (5) and most of the dysplastic dogs were aged 6-12 months and weighed 20-30 kg. The common clinical signs were weight bearing lameness, reluctant to move, poor exercise intolerance and difficulty in rising and sit down frequently. Sedation was useful in obtaining correct positioning for interpretation of different radiographic changes. The mean values of Norberg angle (95.91°), per cent femoral head coverage (56.90%) were lower but DI (0.19) and femoral head neck and shaft angle (138.79°) were higher in dysplastic dogs. The cut-off line of NA and PFHC was <105° and 57.40% for dysplastic dogs. The most common radiographic changes in morphology of hip joint of dysplastic dogs were deformed head and acetabular cavity, osteophytes formation at the cranial acetabular rim and femoral head, thickened neck and incongruence articular surfaces.
