A developmental abnormality of the hip joint, causing an overly shallow acetabulum coupled with a distortion to the head of the femur. These distortions allow for excess movement between the bones.
Mostly a genetic condition, leading to the poor formation of the coxofemoral joint. However, poor nutrition, including over supplementation can be a factor, as can over exercise as a puppy and obesity.
Dogs with hip dysplasia often demonstrate pain, stiffness, limping, discomfort when changing position to sit or stand and problems climbing stairs. Poor gait can also be indicative of hip dysplasia, such as walking in a crouched position, or the inability to straighten the affected leg. In cases of severe hip dysplasia, the dog may struggle to walk at all.
