What condition results from abnormal hip joint development in some breeds?

The story behind the answer

Hip dysplasia is abnormal development of the hip’s ball-and-socket joint (coxofemoral joint), leading to joint laxity, subluxation, pain, and early osteoarthritis. It’s especially common in large breeds like German Shepherds, Labradors, and Golden Retrievers. Genetics play a major role, but rapid growth, excess weight, and inappropriate exercise can worsen it.

Vets screen breeding dogs with OFA or PennHIP evaluations, and management ranges from weight control, joint supplements, and physiotherapy to surgeries like total hip replacement. To remember: “Dys-” means bad, and the problem is in the hip—hip dysplasia. Contrast: elbow dysplasia affects the elbow, luxating patella is a slipping kneecap, and intervertebral disc disease involves the spine.
