Hip dysplasia is a condition that affects the ball-and-socket joint of the hips. The socket aspect of the hip does not cover enough of the ball aspect of the upper thigh bone. This can cause pain in dogs and make it difficult for them to move. It can also cause arthritis in dogs as they get older.
Hip dysplasia occurs most frequently in large and giant breed dogs, though all breeds are susceptible, and it affects purebred dogs more often than mixed breed dogs. It can be inherited from a dog’s parents, so it is important to make sure that dogs do not have hip dysplasia prior to breeding.
