Dysplasia is a bone disease, congenital, hereditary, degenerative and multifactorial, that is, it can occur due to multiple factors. For its appearance there must be a genetic predisposition to which other factors such as poor diet, rapid growth, excess exercise during growth, growth on slippery floors, obesity, old age and the wear it causes can be added…. Studies are currently being carried out to determine the genetic predisposition of individuals, however, for the moment the tests are based on the development or not of this disease and not on its genetic predisposition.
Hip dysplasia consists of the malformation of the acetabulum of the hip and the femoral head, causing the femur and pelvis to not fit correctly, causing pain and even limping the animal.
The different degrees of hip dysplasia are divided as follows:
· Grade A. No signs of hip dysplasia.
· Grade B. Transitional or “borderline” hip.
· Graco C. Mild hip dysplasia.
· Grade D. Moderate hip dysplasia.
· Grade E. Severe hip dysplasia.
The combinations allowed for breeding are: A + A, A + B, A + C, B + B.
