Hip Dysplasia in Dogs: Signs, Causes, and Treatment Options

Hip dysplasia is one of the most common orthopedic conditions in dogs — and one of the most important to understand if you have a large or giant breed. It's a hereditary skeletal condition in which the hip joint doesn't develop properly, causing pain, reduced mobility, and eventually arthritis. Here's what pet parents need to know: how it develops, which signs to watch for, which breeds face the highest risk, and what treatment looks like.

What Is Hip Dysplasia in Dogs?

Hip dysplasia is a developmental condition in which the femoral head (the "ball") and the acetabulum (the "socket") of the hip joint fail to grow at the same rate during puppyhood. According to VCA Animal Hospitals¹, this mismatch creates joint looseness that gradually leads to degenerative joint disease and painful arthritis.

The condition is primarily genetic, but several factors influence how severely it develops:

Signs of Hip Dysplasia in Dogs

Symptoms can appear as early as a few months of age in severely affected puppies, but many dogs don't show signs until one to two years old — or later, as arthritis progresses. Common signs of hip problems in dogs include:

An important note: some dogs have significant changes on X-rays but show little outward sign of pain, while others show obvious discomfort with less radiographic evidence.¹ If your dog shows any of these signs consistently, a veterinary exam is the right next step.

Which Dog Breeds Are Most Prone to Hip Dysplasia?

Hip dysplasia can occur in any breed, but large and giant breeds carry the highest risk. The German Shepherd is consistently documented as one of the most commonly affected breeds — it is the single most significant hereditary health concern for the breed. For a full breakdown of German Shepherd hip dysplasia and other health risks, see the German Shepherd breed guide.

Other breeds with elevated risk include, per PetMD²:

Large mixed-breed dogs are also at meaningful risk. If your dog is a large or giant breed, discussing hip screening and appropriate preventive nutrition with your vet during puppyhood is worthwhile.

How Is Hip Dysplasia Diagnosed?

Diagnosis begins with a physical exam. Your vet will assess gait, range of motion, and signs of joint laxity or pain during palpation. The definitive diagnostic tool is radiography (X-rays), typically performed under sedation to ensure proper positioning and accurate evaluation.¹

The Orthopedic Foundation for Animals (OFA) evaluates submitted hip radiographs using seven grades:

For high-risk breeds, OFA screening of breeding dogs is the primary tool for reducing hereditary transmission. Purchasing a puppy from OFA-screened parents meaningfully lowers the risk of inheriting the condition.

Hip Dysplasia Treatment for Dogs

Treatment depends on the dog's age, body weight, severity, and pain level. Both medical and surgical approaches are available, and many dogs are managed successfully with a combination.

Medical management typically includes:

According to PetMD², the estimated 10-year cost of ongoing medical management can range from $4,800 to $19,200² in medications alone.

Surgical options include:

Frequently Asked Questions

Is hip dysplasia common in German Shepherds?

Yes — German Shepherds are among the breeds with the highest documented rates of hip dysplasia, making it their most significant hereditary health concern. Risk is shaped by genetics, growth rate, and weight. Pet parents with German Shepherds should discuss hip screening with their vet early and consider enrolling in pet insurance before any symptoms appear, since a diagnosis typically becomes a pre-existing exclusion.

Can hip dysplasia in dogs be prevented?

It can't be fully prevented if the genetic predisposition is present, but risk can be reduced meaningfully. Feeding large-breed puppies appropriately portioned food designed for their size controls growth rate — overfeeding is one of the most significant risk factors. Maintaining a healthy weight throughout life reduces joint stress. Purchasing from breeders who OFA-screen their dogs also lowers the likelihood of inheriting the condition.¹

At what age do dogs show signs of hip dysplasia?

Symptoms can appear as early as a few months of age in severely affected puppies, but many dogs don't show signs until one to two years old or later as arthritis develops. Some dogs have significant hip changes on X-rays but remain asymptomatic until middle or older age. This makes early insurance enrollment especially important — once a dog is symptomatic, coverage for that condition is typically no longer available.

Does pet insurance cover hip dysplasia?

Coverage depends on when the policy starts. Hip dysplasia diagnosed before a policy's waiting period ends — or before the policy exists — typically qualifies as a pre-existing condition and is excluded. Enrolling while your dog is young and asymptomatic gives you the broadest coverage window. For more on how pre-existing condition rules apply, see pre-existing conditions and pet insurance.

Unexpected vet bills can happen when you least expect them, but pet insurance may help make those costs more manageable. Having coverage in place can help pet parents feel more prepared for emergency care, surgery, diagnostics, and treatment for covered conditions.
