- Hip Dysplasia is a hereditary disease that affects the hip joints of dogs. Hip dysplasia is characterized by a looseness in the hip joint that causes abnormal wear and tear on the femoral head (the ball part of this ball and socket joint) and the acetabulum (the socket). The wear and tear leads to malformation of the ball and socket, and can lead to arthritis. Dogs predisposed to hip dysplasia, unlike children, are born with normal hip joints. Hip dysplasia can be seen in some dogs as young as five or six months of age. In other dogs, signs do not develop until after the dog matures. Hip pain is generated by the abnormal arthritic bones rubbing against each other. Arthritis will worsen with time unless surgical treatment is administered.
