Dog Hip Dysplasia: Symptoms, Diagnosis, Surgery & Management 2026
Hip dysplasia is one of the most common orthopaedic conditions in dogs, especially in large and giant breeds. It occurs when the hip joint develops abnormally, causing the ball and socket to fit loosely. Over time, this leads to cartilage damage and chronic osteoarthritis — a source of significant pain.
What Is Hip Dysplasia?
In a healthy hip, the femoral head (ball) fits snugly into the acetabulum (socket). In hip dysplasia, the joint develops incorrectly — the socket may be too shallow or the ligaments too loose — causing subluxation (partial dislocation) with every step, grinding away cartilage and triggering inflammation. Hip dysplasia is primarily genetic but is worsened by rapid growth during puppyhood.
Most commonly affected breeds: German Shepherds, Labrador Retrievers, Golden Retrievers, Rottweilers, Great Danes, Saint Bernards, and Bulldogs.
Signs and Symptoms
- Reluctance to rise, climb stairs, or jump
- “Bunny hopping” gait (both back legs moving together when running)
- Swaying or wobbly rear end
- Muscle wasting in the hindquarters with over-developed front shoulders
- Pain or yelping when hips are manipulated
- Stiffness after rest that improves with gentle movement
- Reduced activity and exercise intolerance
Diagnosis: X-Rays and Grading
Diagnosis is confirmed with radiographs (X-rays) under light sedation. The OFA system rates hips from Excellent to Severely Dysplastic. The PennHIP method measures joint laxity via a Distraction Index and can detect dysplasia in puppies as young as 16 weeks. Vets also assess for osteoarthritic changes such as bone spurs and joint space narrowing.
Treatment: Surgery vs. Medical Management
Surgical options: Triple Pelvic Osteotomy (TPO) for young dogs under 10 months with no arthritis; Juvenile Pubic Symphysiodesis (JPS) before 20 weeks; Femoral Head and Neck Excision (FHO) for smaller dogs; and Total Hip Replacement (THR) — the gold standard for mature dogs with severe dysplasia, often returning near-normal function.
Medical management: weight management (most effective non-surgical intervention), low-impact exercise (swimming, leash walks), NSAIDs, joint supplements, physical rehabilitation, hydrotherapy, Adequan injections, and laser therapy or acupuncture as adjuncts.
Living With a Hip Dysplastic Dog
Many affected dogs live comfortable lives with appropriate care: maintain a lean weight; provide orthopaedic bedding; use ramps instead of stairs; maintain regular gentle exercise; and schedule regular vet check-ins as arthritis progresses. If buying from a susceptible breed, always request OFA or PennHIP certification for both parents.
