Hip Dysplasia In Dogs
Hip dysplasia is one of the most common skeletal conditions in dogs, and one of the leading causes of arthritis and rear-leg lameness. It happens when the hip's ball-and-socket joint doesn't fit together properly, so the joint grinds instead of gliding — causing wear, inflammation, and discomfort over time. The good news: with early diagnosis and a good management plan, the large majority of affected dogs go on to live active, comfortable lives. This guide covers what hip dysplasia is, the first signs to watch for, what causes it, which breeds are most at risk, and how it's diagnosed and managed. Throughout, your veterinarian should be your partner in diagnosis and treatment.
What Is Hip Dysplasia?
The hip is a ball-and-socket joint: the head of the femur is the "ball," and the pelvis forms the "socket." In a healthy joint, the ball rotates smoothly within the socket, cushioned by a layer of cartilage and held stable by a strong ligament and the surrounding joint capsule. Hip dysplasia is a developmental problem — during a puppy's growth, the ball and socket don't grow at the same rate, leaving a loose, poorly fitting joint. As the body tries to stabilize that loose hip, the resulting wear can progress to osteoarthritis (degenerative joint disease). Severity ranges widely, from changes you'd barely notice to significant pain and mobility loss.
First Signs and Symptoms of Hip Dysplasia in Dogs
The first signs often appear between 6 months and 2 years of age, though in many dogs symptoms don't show until middle age or later, once arthritis has set in. Because dogs instinctively hide discomfort, subtle early changes are easy to miss. Common signs include:
- Limping or favoring one or both hind legs
- Difficulty rising, or being slow to get up
- Reluctance to run, jump, or climb stairs
- A "bunny hop" gait — using both hind legs together — or a swaying, waddling walk
- Shifting weight onto the front legs
- Reduced range of motion in the hind legs, or muscle wasting over the hips
- Stiffness and soreness around the hips, especially after rest or in cold, damp weather
- Losing interest in play, walks, or activities they used to enjoy
If you notice any of these, see your veterinarian for an evaluation. Catching it early gives you the most options to keep your dog comfortable and slow the condition's progression.
What Causes Hip Dysplasia in Dogs?
Hip dysplasia is primarily an inherited condition, but several factors influence whether — and how severely — a genetically susceptible dog develops it:
- Genetics. If a dog's parents had hip dysplasia, the offspring are at greater risk. A dog can also carry and pass on the gene without showing the condition itself, which is part of why it runs in certain breeds and lines.
- Growth and diet. How much a puppy eats — and when — plays a major role. In one classic study of at-risk Labrador puppies, roughly two-thirds of those fed all they wanted developed hip dysplasia, versus about a third of those fed measured meals. A study of German Shepherds found overweight puppies were nearly twice as likely to develop it. Too few minerals like calcium can also affect joint development.
- Inappropriate exercise. Genetically susceptible dogs are at higher risk if over-exercised while young. Exercise matters, but aim for moderate, low-impact activity and avoid hard running on pavement, high-impact jumping that lands on the hind legs, and standing on the back legs.
One specific factor worth discussing with your vet is the timing of spaying or neutering, which some research has linked to joint development in large breeds — we cover that in neutering and hip dysplasia.
Which Breeds Are Most at Risk?
Hip dysplasia has the highest incidence in large and giant breeds, including German Shepherds, Labrador Retrievers and other retrievers, Golden Retrievers, Rottweilers, Bullmastiffs and other mastiffs, Great Danes, St. Bernards, and Staffordshire and pit bull terriers. That said, dogs of any size or breed — including mixed breeds — can inherit it. In fact, by percentage of dogs screened, some smaller breeds such as French bulldogs and pugs rank among the most affected, according to data from the Orthopedic Foundation for Animals. If you own an at-risk breed, owners often pair veterinary care with a daily joint supplement; for breed-specific guidance, see our note on the best joint supplement for German Shepherds.
How Hip Dysplasia Is Diagnosed
A veterinarian diagnoses hip dysplasia with a physical examination, hands-on manipulation of the hips to check for looseness and range of motion, and radiographs (x-rays), sometimes supported by additional imaging. Early diagnosis matters, because the sooner you start a management plan, the more comfortable you can keep your dog as they age.
Can You Prevent Hip Dysplasia?
Because it's largely genetic, there's no way to guarantee prevention — but you can lower the odds and the severity. Start healthy habits early: feed a healthy, properly portioned diet to support normal bone and joint development, keep your dog at a lean body weight (extra pounds load already-vulnerable joints), and provide regular, moderate exercise while avoiding high-impact activity in young puppies. Go easy on table scraps and fatty foods. And if you're bringing home a new puppy of an at-risk breed, research the breeder and choose one who does appropriate hip screening on their breeding dogs.
Treatment and Management Options
There's no cure for hip dysplasia, but a lot can be done to keep a dog comfortable and slow the progression. Your veterinarian will tailor a plan, which often combines several of the following:
- Weight management — keeping your dog lean is one of the single most effective ways to reduce stress on the hip joints.
- Controlled exercise — start with short walks and build gradually to maintain muscle and range of motion without over-exertion.
- Swimming and hydrotherapy — excellent non-weight-bearing exercise for dogs who are able.
- Comfortable, warm bedding — a well-padded bed away from cold, damp drafts, since discomfort often feels worse in the cold.
- Veterinary medication — your vet may prescribe medications to manage pain and inflammation.
- Surgery — in more severe cases; ask your vet when they'd recommend it, and don't hesitate to get a second or third opinion.
- Daily joint supplements — many owners add one as part of ongoing supportive care.
A note on pain medication: NSAIDs and other pain drugs can help a dog who's hurting, but they should be given only at the smallest effective dose for the shortest time, under veterinary guidance, because side effects like liver, kidney, and digestive problems are real. They ease symptoms rather than fixing the joint. For a fuller look at the options, see our guide to what you can give a dog for pain, and for everyday, at-home comfort measures, our guide to dog joint pain relief.

Daily Joint Support with Flexpet
Alongside the plan your veterinarian recommends, many owners use a daily joint supplement as part of supportive care. Flexpet is an all-natural daily supplement formulated to nourish the joints and support healthy cartilage, the joint's natural lubricating fluid, and a healthy inflammatory response. It comes in a chewable tablet dogs love, with no artificial coloring or flavoring. Flexpet is a supplement, not a medication — it is not intended to diagnose, treat, cure, or prevent hip dysplasia or any other disease, and it is not a substitute for veterinary care. It contains:
- CM8® (Cetyl Myristoleate) — a naturally occurring fatty acid studied for its role in supporting joint comfort and a healthy inflammatory response.
- Glucosamine — plays a key role in cartilage construction; read more about glucosamine for dogs.
- MSM — a naturally occurring sulfur compound the body uses to form connective tissue.
- Hydrolyzed Collagen Type II — tissue-oriented nutritional support for the cartilage that cushions the joints.
- Bromelain — a plant enzyme from pineapple that supports a healthy inflammatory response.
- Enzyme Blend — helps the body absorb larger molecules like CM8®.
Flexpet comes with a 90-day satisfaction guarantee — if you're not satisfied, return your first order (up to three empty pouches/bottles) for a full refund of the purchase price, less shipping and handling. Questions? Call our customer care team M–F, 9am–6pm EST at 1-800-505-0575.
Finding out your dog has hip dysplasia can feel overwhelming, but it doesn't have to be the end of an active life. Educate yourself, work closely with your veterinarian, and keep up healthy habits — and your dog can stay comfortable and happy by your side for years to come.
