Hip Dysplasia in Dogs: Signs, Causes & Treatment 2026

Hip dysplasia is one of the most prevalent and well-studied orthopaedic conditions in dogs. For many dog owners, a hip dysplasia diagnosis carries significant emotional weight — the idea of a beloved dog living with chronic pain is difficult to accept. However, the good news is that with early detection, appropriate management, and the right support, many dogs with hip dysplasia lead comfortable, active lives.

This comprehensive guide explains everything dog owners need to know about hip dysplasia in 2026 — from its causes and risk factors to the full range of treatment options now available.

What Is Hip Dysplasia in Dogs?

Hip dysplasia is a developmental abnormality of the hip joint in which the ball (femoral head) and socket (acetabulum) of the hip don’t fit together correctly. Instead of the smooth, gliding movement of a normal hip joint, a dysplastic hip has excessive looseness (laxity), causing the ball to shift within — or partially out of — the socket during movement.

Over time, this abnormal joint movement causes damage to the cartilage lining the joint surfaces, leading to progressive osteoarthritis (degenerative joint disease). The arthritis itself — not necessarily the malformation — is what causes the chronic pain and stiffness that dog owners observe as the disease progresses.

Hip dysplasia can affect one hip (unilateral) or both (bilateral). Bilateral hip dysplasia is very common, though one side is often more severely affected than the other.

Which Dogs Are Most at Risk for Hip Dysplasia?

Hip dysplasia is primarily a genetic condition, though environmental and nutritional factors influence how severely it expresses. It’s most common in large and giant breeds, including:

• German Shepherds
• Labrador Retrievers
• Golden Retrievers
• Rottweilers
• Great Danes
• Saint Bernards
• Mastiffs
• Bernese Mountain Dogs

Smaller breeds can also develop hip dysplasia, but it’s less common and often less severe. Environmental risk factors that influence severity include rapid growth rate, excessive caloric intake during puppyhood (causing the puppy to grow too quickly), high-impact exercise in young dogs whose joints are still developing, and obesity at any age (which increases mechanical stress on already compromised joints).

Signs and Symptoms of Hip Dysplasia in Dogs

Hip dysplasia can cause symptoms as early as 4–6 months of age in severely affected dogs, but many dogs don’t show obvious signs until the secondary arthritis develops — sometimes not until middle age or later. Signs vary by the dog’s age and disease stage:

In young dogs (4–18 months):

• Bunny-hopping gait (moving both back legs together instead of alternately) when running
• Reluctance to climb stairs, jump, or rise from lying down
• Stiffness or lameness after exercise or first thing in the morning
• Narrow stance in the hind end
• Audible clicking of the hip joints
• Decreased muscle mass in the hindquarters

In adult and senior dogs with progressed arthritis:

• Chronic hindlimb lameness, especially after rest
• Significant muscle wasting in the back legs
• Reluctance to exercise or shortened activity tolerance
• Behavioral changes — irritability or reluctance to be touched on the hindquarters
• Difficulty posturing to defecate or urinate
• Obvious pain on manipulation of the hip

Diagnosing Hip Dysplasia

Diagnosis is typically made through a combination of physical examination and radiography (X-rays). Your veterinarian will observe your dog’s gait, range of motion, and response to joint manipulation. Specific tests — such as the Ortolani sign (a positive “clunk” felt when the dysplastic hip is reduced back into the socket during manipulation) — help confirm joint laxity.

X-rays taken with the dog sedated or under anesthesia allow precise assessment of joint conformation. Standard hip extended view films are commonly used. More specialized imaging — including PennHIP radiography, which measures distraction index to quantify hip laxity — can detect dysplasia earlier and more accurately than standard views.

For dogs being bred, formal hip evaluation by breed registries such as the OFA (Orthopedic Foundation for Animals) is highly recommended to reduce the incidence of hip dysplasia in future generations.

Treatment Options for Hip Dysplasia in Dogs

Treatment depends on the dog’s age, severity of dysplasia, degree of arthritis, body weight, and the owner’s resources. Options range from conservative medical management to surgical correction.

Conservative / Medical Management:

• Weight control: Maintaining an ideal lean body weight is one of the single most impactful interventions. Even modest weight loss dramatically reduces pain and improves mobility.
• Controlled, low-impact exercise: Swimming and leash walking are ideal. Avoid high-impact activities like jumping, rough play, and long runs, especially on hard surfaces.
• NSAIDs (non-steroidal anti-inflammatory drugs): Prescription medications like carprofen, meloxicam, or grapiprant provide significant pain relief and improve quality of life. These should be used under veterinary supervision with monitoring of kidney and liver function.
• Joint supplements: Omega-3 fatty acids, glucosamine, and chondroitin have evidence supporting their use in managing osteoarthritis, though they’re not a standalone treatment.
• Physical therapy and hydrotherapy: Canine rehabilitation therapy strengthens the muscles supporting the hip and improves joint function.
• Injections: Intra-articular injections of hyaluronic acid or corticosteroids provide temporary relief. Platelet-rich plasma (PRP) and stem cell therapy are emerging treatments with promising but still evolving evidence.

Surgical Options:

• Juvenile Pubic Symphysiodesis (JPS): Performed in puppies under 5 months of age before obvious arthritis develops; alters pelvic development to improve hip conformation.
• Triple Pelvic Osteotomy (TPO): Suitable for young dogs (under 10–12 months) without significant arthritis; surgically rotates the acetabulum to better cover the femoral head.
• Femoral Head and Neck Ostectomy (FHO): Removes the femoral head, eliminating bone-on-bone contact. Very effective for small and medium dogs; variable results in large breeds.
• Total Hip Replacement (THR): The gold standard surgical treatment; replaces the entire diseased hip with a prosthetic implant. Produces excellent long-term outcomes in appropriately selected candidates.
