Hip dysplasia is a malformation of the hip joint where the ball of the femur doesn't fit cleanly into the socket of the pelvis. The looseness causes wear, inflammation, and arthritis. In severe cases, the dog can't comfortably walk, run, or sit.
Every bulldog breed has hip risk, including the OEB. The condition is partially heritable, which is why responsible breeders screen their breeding stock and why buyers ask to see results.
Honest framing. OBBA does not require hip testing for registration. Many of our best breeders test voluntarily. Some excellent OEBs come from lines that haven't been formally tested but have generations of sound, athletic dogs in front of them. Both can be acceptable. Untested-and-unknown is the only option to avoid.
Symptoms
Mild to moderate cases may show:
- Stiffness when getting up, especially in the morning or after rest
- Reluctance to climb stairs or jump into a vehicle
- "Bunny hopping" gait - both back legs moving together
- Loss of muscle in the hindquarters as the dog avoids using them
- Audible clicking from the hip joint
Severe cases show clear lameness, pain on hip manipulation, and visible reluctance to move. Symptoms usually start showing between 6 months and 2 years, but mild cases can go undetected until middle age.
Diagnosis
A vet diagnoses hip dysplasia with x-rays. There are two main scoring systems used in North America:
- OFA (Orthopedic Foundation for Animals). The standard for breeding stock. Final certification at 24 months. Grades: Excellent, Good, Fair, Borderline, Mild, Moderate, Severe. Excellent through Fair are considered breedable.
- PennHIP. A measurement-based system that uses a "distraction index" to quantify joint laxity. Can be done as early as 16 weeks. Better at predicting future arthritis than OFA in some studies.
OFA results are publicly searchable at offa.org. If a breeder claims their dog has an OFA score, you can verify it directly with the dog's registered name or registration number.
Prevention through breeder selection
You can't prevent hip dysplasia in your puppy after the fact. The genetic component was decided when the litter was bred. What you can do is buy from a breeder who has screened their stock.
Reasonable questions for a breeder:
- Have the sire and dam been hip-tested? OFA or PennHIP?
- Can I verify on offa.org?
- What about the grandparents and siblings?
- If untested: have any of your previous puppies developed hip issues?
A breeder who answers honestly - including admitting if they haven't tested - is a breeder worth working with. A breeder who gets defensive or evasive is telling you something.
If your dog has it
Mild and moderate cases are manageable. The basics:
- Weight management. The single biggest factor. Every extra pound is extra force on a bad joint. Keep your OEB lean - visible waist, palpable ribs.
- Joint supplements. Glucosamine, chondroitin, omega-3s, and green-lipped mussel have evidence behind them. Joint supplements guide.
- Controlled exercise. Daily moderate exercise builds the muscle that supports the joint. Avoid high-impact: no fetch on hard surfaces, no jumping from heights, no agility.
- Anti-inflammatories. NSAIDs (Carprofen, Meloxicam, Galliprant) for flare-ups, prescribed by your vet.
- Rehab / physical therapy. Underwater treadmill work, laser therapy, and targeted strengthening can substantially extend mobility.
When surgery makes sense
Severe cases with poor quality of life despite conservative management benefit from surgery. The two main options:
- FHO (femoral head ostectomy). Removes the ball of the femur. The body forms a "false joint" of fibrous tissue. Cheaper ($1,500-$3,000), works well on dogs under 50 lbs. Larger OEBs see less reliable outcomes.
- THR (total hip replacement). Replaces the entire hip joint with a prosthesis. Gold standard for an active large-breed dog. $4,000-$8,000 per hip. Most OEBs do extremely well with THR.
Realistic lifetime costs
A mild case managed conservatively costs maybe $40-$80 a month in supplements and occasional NSAIDs across the dog's life. A severe case requiring bilateral total hip replacement plus rehab can run $12,000-$18,000 over the dog's lifetime.
Pet insurance taken out before symptoms appear typically covers most of the surgical costs. Pet insurance guide.
