The incidence ofhip displasia in 60 Labrador Retrievers was evaluated at the Small Animal Clinic, Faculty ofVeterinary Medicine, San Marcos University, Lima, following radiological procedures dictated by the Federación Cinológica Internacional (FCI). Two groups, comprised of30 mal e and 30 female dogs, were fonned at random and data on sex, age, clínical symptoms and coat color were recorded. Measurement of the Norberg angle in x-rays of both coxofemoral joints was used to determine the presence or absence of malformations. Hip displasia was diagnosed in 61.7% (37/60) ofthe cases, an elevated incidence compared to data from other countries. Both sexes were equally affected (no statistically significant difference) and most of the displasias were bilateral. Beca use only 48.64 %± 16.10 ofthe affected animals exhibited clínical symptoms, it is clear that radiological study is essential for precise and definitive diagnosis of canine hip dysplasia.
