Recent information about hip dysplasia.

Dogs suffering from HD have a genetic background, but the releasing factors are many. Two of the most important are overnutrition and overexercising, especially in the young puppy. Radiography can give an estimate of the degree of secondary OA, and by evaluating the laxity in the hip joints at an early age, it seems to be possible to predict the chances for later development of OA. The eradication program has to be instituted in such a way that only the best dogs are accepted into breeding programs. It seems to be more efficient to eradicate the genetic part of the etiology by creating a breeding index by means of evaluating the offspring of the male dogs.
