Hip dysplasia in dogs
Hip dysplasia is the most common hereditary orthopedic disease in medium and large dogs. It consists of a malformation of the hip joint where the femoral head does not fit perfectly into the acetabulum, causing joint laxity, chronic pain and development of arthritis. It affects both hips in most cases.

🚦 Urgency triage: yellow vs red flag
🟡 Yellow flag — monitor / vet in 24-72h
- rising difficulty / stair refusal / intermittent lameness
🔴 Red flag — emergency NOW
- severe pain / refusal to walk / yelping on movement
Early signs (watch if your dog)
- Has difficulty getting up after sleeping
- Makes noise going up stairs or jumping on the sofa
- Walks with rear end swaying (bunny hop gait)
- Tires quickly in games that used to last hours
- Sits abnormally (one leg stretched to the side)
- Loses thigh muscle mass
Most affected breeds
| Breed | Prevalence | Typical diagnosis age |
|---|---|---|
| English Bulldog | 70% | 6-18 months |
| Saint Bernard | 45% | 6-18 months |
| Golden Retriever | 20% | 1-3 years |
| Labrador Retriever | 12% | 1-3 years |
| German Shepherd | 20% | 6 months-2 years |
Diagnosis
Definitive diagnosis is by X-ray under light sedation. The international gold standard is OFA (Orthopedic Foundation for Animals) certification which classifies into: Excellent, Good, Fair, Borderline, Mild, Moderate, Severe.
- Ventrodorsal X-ray with extended hips (mandatory)
- PennHIP method (measures early joint laxity from 4 months)
- Manual orthopedic exam (Ortolani test)
Prevention
- Require OFA/PennHIP certificate from parents before buying puppy
- Maintain ideal weight throughout dog's life
- Avoid impact exercise (stair jumping) until 12 months
- Supplement with chondroprotectors after 5 years
- Prefer non-slip surfaces at home
What dysplasia does to the joint
Na Hip dysplasia, a articulação do quadril se forma de maneira frouxa, e o atrito repetido desgasta a cartilagem ano após ano. A doença nasce na estrutura, mas o dano é progressivo e o controle começa antes da dor aparecer.
Na ficha clínica, Hip dysplasia aparece como medium. Guarde essa informação: ela decide entre 'marcar consulta' e 'ir agora'.
Mistakes that speed up wear
- Keeping the animal overweight because 'it's still a puppy'
- Impact exercise (jumping, long stairs) as the main activity
- Smooth floors at home, forcing compensation at every step
- Treating only when pain stops walking, when damage is already installed
Measuring progress without frustration
No manejo de Hip dysplasia, o progresso se mede em semanas, não em dias. Marque no calendário a reavaliação e escolha 2-3 indicadores simples (dor ao toque, frequência das crises, disposição no passeio) para acompanhar sempre do mesmo jeito.
O maior risco do tratamento de Hip dysplasia é abandonar cedo o que funciona devagar. Antes de mudar o plano, dê a ele o intervalo que o veterinário definiu; mudança sem intervalo não permite ler resultado nenhum.
Se qualquer sinal regredir, o critério de retorno desta página vale: At first sign of limping.

Frequently Asked Questions
What's the right age for dysplasia exam?
Standard OFA X-ray: from 24 months. PennHIP: from 4 months. If the dog shows symptoms, exam immediately regardless of age.
Can a dog with dysplasia live well?
Yes. With weight control, adequate activity, supplementation and regular vet monitoring, dogs with mild to moderate dysplasia live an almost normal life.
Is surgery always necessary?
No. About 60% of cases are controlled with conservative treatment. Surgery is indicated when there is persistent pain or functional loss.
Can a puppy from dysplasia-free parents have it?
Yes, but the risk is much lower. Dysplasia has a strong genetic component but is not 100% hereditary — nutrition, exercise and weight during growth also influence.
How much does dysplasia surgery cost?
In the US, Triple Pelvic Osteotomy (TPO): $3,000-$6,000. Total hip replacement: $6,000-$12,000 per hip. Values vary by city.
At what age does Hip dysplasia show up?
Per the clinical profile on this page, the typical onset age is 6 months to 2 years. Predisposed breeds can show signs earlier, and early screening changes the prognosis.
How severe is Hip dysplasia?
Hip dysplasia is classified as: medium. That rating sets how fast you need care; severe cases have no safe waiting period at home.
When should I take my pet to the vet for Hip dysplasia?
The practical reference on this page is: At first sign of limping. If you're torn between 'watch' and 'go', go: nobody regrets checking early.
