The study was conducted with the objective to compare the radiographic morphometry of proximal femur and hip joint on client owned healthy Labrador Retriever (N=12) and German Shepherd (N=12) breeds of dog presented to referral veterinary polyclinic (RVP) & Division of Surgery, IVRI, Izatnagar (U.P.) India. All the dogs were screened for canine hip dysplasia with inclusion criteria of having norberg angle over 105o
and no pathological changes in femoral head and neck and acetabulum. Those with the evidence of fracture, arthritis, sequel of old sepsis, skeletal dysplasia, were excluded. Radiographs of each animal was taken in standard hip extended position under anaesthesia.
In the present study German Shepherd group revealed lower Canal Flare Index (CFI) values and a more stovepipe femoral geometry as compared to Labrador Retriever. However, weight wise no significant variations were found in all acetabular and proximal femoral radiographic measurements between Labrador Retriever and German Shepherd group. In an overall and sex-wise comparison Labrador group showed a high degree of steepness of cranial acetabular edge (high acetabular index angle).
