ABSTRACT

Hip dysplasia (HD) is one of the most important canine orthopedic disease because of its high occurrence and severe consequences in the quality of life of many dogs. The aim of this study was to evaluate epidemiologically and statistically 180 dysplastic dogs attended at the Veterinary Teaching Hospital, Sao Paulo State University, in a five year period. It was correlated the severity of clinical signs and the HD from radiographs of 120 animals. Sex, body weight and age of animal at time of diagnosis were not a risk factor for severity of HD or clinical signs. More than 50% of the Rottweillers, German Shepherds, Labradors Retrievers and Pit Bulls presented with severe HD. Mean body weight of dogs with severe HD was 34.31kg.  From 180 evaluated dogs, 22.22% had osteoarthritis at time of diagnosis. Around 45% of pure breed dogs presented with severe HD versus 27.27% of mix breed dog. A total of 42.11% of clinically asymptomatic dogs had severe radiographic signs of HD. There was no significant correlation between the severity of clinical signs and radiographic lesions
