Hip Dysplasia in Giant Breeds: Signs, Treatment, and Prevention

Hip dysplasia is an orthopedic condition affecting giant breed dogs — and one of the most misunderstood.

The good news: a diagnosis doesn't mean your dog can't live a happy, active life. With the right combination of weight management, exercise, environmental support, and veterinary care, many big dogs with hip dysplasia stay comfortable and mobile for years. For the bigger picture, start with our giant breed joint health guide.

What Is Hip Dysplasia?

A healthy hip works like a snug ball-and-socket joint. In dysplasia, the ball and socket don't fit together properly, so the joint moves abnormally and wears unevenly over time. That can lead to inflammation, cartilage damage, arthritis, pain, and reduced mobility. It can affect one or both hips and ranges from mild to severe.

Why Giant Breeds Are at Higher Risk

Hip dysplasia is common enough in large and giant breeds that the Orthopedic Foundation for Animals (OFA) recommends routine hip screening in breeding dogs. Rates vary widely by breed — some giant breeds, such as Saint Bernards and Mastiffs, screen dysplastic at notably higher rates than others like the Great Dane. Several factors stack the deck:

• Genetics — the strongest single factor, which is why breeder screening matters
• Rapid growth — giant breed puppies put on enormous weight while their skeletons are still forming
• Body weight — more mass means more force through the joint
• Environment and nutrition — growth rate, body condition, and activity can all influence how joints develop

Signs to Watch For

Symptoms vary, and some dogs show signs young while others don't until adulthood. Common indicators include:

• Difficulty rising, especially after rest
• “Bunny hopping” with both back legs when running
• Reluctance to jump or climb stairs
• Reduced activity or shorter walks
• Rear-end weakness or a swaying, stiff gait

Because these changes come on gradually, they're easy to mistake for normal aging.

How It's Diagnosed

Veterinarians diagnose hip dysplasia through a physical exam (range of motion, comfort, gait), X-rays to assess the joint and grade severity, and a review of history and symptoms. Earlier diagnosis generally means more management options.

Treatment and Management

Treatment depends on severity and the individual dog, but usually centers on:

• Weight management — often the single most important factor; even modest excess weight increases stress on the hips
• Controlled exercise — consistent, low-impact movement like walking and swimming over intense bursts
• Physical rehabilitation — therapeutic exercise, hydrotherapy, and balance work
• Pain management — medications when appropriate, guided by your vet
• Surgery — considered in more severe cases, determined with a veterinary specialist

Can It Be Prevented?

No approach eliminates risk, but you can support healthy hips: keep your dog lean, feed appropriately during growth, avoid excessive high-impact activity in puppyhood, build supporting muscle, and provide good traction at home.

What About Joint Supplements?

Joint supplements can't cure hip dysplasia, but many owners include them as part of a comprehensive mobility plan to support cartilage health, joint function, and a normal inflammatory response. Common ingredients include glucosamine, chondroitin, MSM, eggshell membrane, and boswellia. Our guide on what to look for in a giant breed supplement breaks them down.

The Bottom Line

Hip dysplasia is common in giant breeds, but it doesn't define your dog's future. Early recognition, weight management, muscle preservation, environmental support, and veterinary care can make a real difference in long-term comfort and mobility.
