Hip dysplasia is a developmental orthopedic condition where the hip joint does not form properly, resulting in joint laxity (looseness), progressive cartilage damage, and eventually osteoarthritis. It is one of the most common orthopedic problems in dogs — particularly in large and giant breeds — and it is a leading cause of chronic hind-limb pain and mobility loss.

The condition cannot be cured, but it can be managed. The challenge for owners and veterinarians is deciding which combination of medical management, lifestyle modification, and potentially surgery gives each dog the best quality of life.

Which Dogs Are at Risk

Hip dysplasia has a strong genetic component, but environmental factors — growth rate, body weight, exercise during development — influence whether a genetically predisposed dog develops clinical disease.

Breeds with elevated risk include:

  • German Shepherds, Labrador Retrievers, Golden Retrievers
  • Rottweilers, Mastiffs, Saint Bernards, Newfoundlands
  • Bulldogs, Pit Bulls, Chow Chows
  • Bassett Hounds, Bloodhounds, Chesapeake Bay Retrievers

Any dog can develop hip dysplasia, including mixed-breed dogs. Large and giant breeds carry the highest risk, but small dogs are not immune.

Signs of Hip Dysplasia

Clinical signs vary by age and severity. Some dogs show obvious discomfort as puppies; others develop gradual stiffness as adults.

In Puppies and Young Dogs (4–12 Months)

  • Bunny-hopping gait (both hind legs move together)
  • Reluctance to climb stairs or jump into the car
  • Swaying hindquarters when walking
  • Pain when the hips are extended during examination

In Adult and Senior Dogs

  • Difficulty rising from a lying position
  • Stiffness after rest that improves with movement
  • Loss of thigh muscle mass, increased shoulder mass (shifting weight forward)
  • Decreased willingness to exercise
  • Audible clicking or grating in the hip joint
  • Narrowing of the stance behind

Signs can be subtle early on. A dog that no longer jumps on the bed or hesitates before a walk may be compensating for hip pain rather than simply aging.

How Hip Dysplasia Is Diagnosed

Physical Examination

A veterinarian will assess gait, hind-limb muscle mass, and range of motion in the hips. The Ortolani sign — a palpable "clunk" when the femoral head slips back into the acetabulum during manipulation — indicates hip laxity, a hallmark of dysplasia.

Radiographs (X-Rays)

Hip radiographs under sedation or general anesthesia are the primary diagnostic tool. Standard hip-extended views can show joint laxity, shallow acetabulum (hip socket), and secondary arthritic changes.

PennHIP is a specialized radiographic technique that uses a distraction index to quantify hip laxity more precisely than standard views. It can detect risk in puppies as young as 16 weeks, which is important because early surgical options (JPS, DPO/TPO) must be performed before skeletal maturity.

OFA (Orthopedic Foundation for Animals) hip evaluation is the most widely used screening tool, but it is not highly predictive in dogs under one year. PennHIP provides earlier and more accurate laxity measurements.

Advanced Imaging

CT scans may be used in surgical planning, particularly for total hip replacement. MRI is rarely needed for hip dysplasia itself but may help evaluate concurrent soft-tissue conditions.

Surgical Treatment Options

Surgery is not always necessary. The decision depends on the dog's age, severity of disease, clinical signs, body weight, activity level, and the owner's financial situation.

Juvenile Pubic Symphysiodesis (JPS)

  • Who: Puppies under 18 weeks old with confirmed hip laxity but minimal arthritic changes
  • What it does: Prematurely closes the pubic growth plate, altering pelvic growth to improve hip joint congruity as the puppy matures
  • Effectiveness: Can reduce hip dysplasia severity by 40–46% in acetabular coverage angles. Does not eliminate the condition but can significantly reduce its progression
  • Timing is critical: This procedure must be performed before 18–20 weeks of age, which means early screening (PennHIP at 16 weeks) is essential. Many puppies are diagnosed too late for this option
  • Cost: Generally $1,500–$3,000

Double or Triple Pelvic Osteotomy (DPO/TPO)

  • Who: Young dogs (typically 5–12 months) with hip laxity but no significant arthritic changes
  • What it does: Cuts and repositions pelvic bones to rotate the acetabulum, improving coverage of the femoral head
  • Effectiveness: Can improve joint congruity in carefully selected patients, but long-term outcomes are variable. Some surgeons have moved away from this procedure because total hip replacement has become more predictable
  • Limitations: Cannot be performed once significant arthritis has developed, which narrows the eligible patient population
  • Cost: $3,000–$6,000 per hip

Total Hip Replacement (THR)

  • Who: Mature dogs (typically over 8–12 months) with significant hip pain or mobility loss that has not responded to medical management. Most common in medium, large, and giant breeds
  • What it does: Replaces the entire hip joint (ball and socket) with prosthetic implants — typically a titanium femoral stem and a polyethylene (plastic) or metal acetabular cup. Both cemented and cementless implant systems are available
  • Effectiveness: Widely considered the gold standard for severe hip dysplasia in adult dogs. Published success rates range from 80–98% for return to normal limb function, with most modern case series reporting 90–95%. Most dogs can walk on the operated leg the day after surgery
  • Recovery: Full recovery takes approximately 8–12 weeks. Activity is strictly restricted during healing. Bilateral hip dysplasia requires staged surgeries, typically 2–3 months apart. Often only one hip needs replacement to achieve good function
  • Complications: Infection, implant loosening, femur fracture — combined complication rate under 10% with modern techniques and experienced surgeons
  • Cost: $8,000–$12,000+ per hip (including consultation, surgery, hospitalization, and follow-up)

Femoral Head Ostectomy (FHO)

  • Who: Dogs with hip pain where THR is not feasible — most commonly small and medium dogs under 45–60 lbs, or cases where cost, availability, or concurrent conditions preclude THR
  • What it does: Removes the femoral head and neck, eliminating bone-on-bone contact. The body forms a false joint (pseudarthrosis) from scar tissue
  • Effectiveness: Eliminates the bone-on-bone pain of hip dysplasia but does not restore normal joint mechanics. Best outcomes in smaller dogs and cats. Larger dogs may have residual gait abnormalities
  • Recovery: Faster initial recovery than THR (4–6 weeks), but physical rehabilitation is important for optimal function
  • Cost: $2,000–$5,000 per hip

Which Surgery Is Right?

Goal Prevent progression Improve coverage Restore normal function Eliminate pain
Cost per hip $1,500–3,000 $3,000–6,000 $8,000–12,000 $2,000–5,000

Non-Surgical Management

Not every dog with hip dysplasia needs surgery. Many dogs — particularly those with mild to moderate disease — can be managed long-term with a combination of:

Weight Management

This is the single most impactful non-surgical intervention. Reducing body weight decreases mechanical stress on abnormal hip joints. Even a 10–15% reduction in body weight can produce visible improvement in comfort and mobility.

Exercise Modification

Low-impact activities — controlled leash walks, swimming, underwater treadmill therapy — maintain muscle strength without excessive joint stress. High-impact activities (jumping, hard running on concrete) should be limited.

Physical Rehabilitation

Professional rehabilitation (veterinary physiotherapy) can improve range of motion, build supporting muscle, and reduce compensatory strain. Modalities include therapeutic exercises, laser therapy, and hydrotherapy.

Medications

  • NSAIDs (carprofen, meloxicam, grapiprant, robenacoxib): Reduce inflammation and pain. Long-term use requires periodic blood work to monitor kidney and liver function. Different NSAIDs suit different dogs — see our guides on Rimadyl (carprofen) for dogs, meloxicam for dogs, and Galliprant (grapiprant) for dogs for individual drug profiles.
  • Librela (bedinvetmab): A monthly anti-NGF monoclonal antibody injection approved for canine osteoarthritis pain. Works through a different mechanism than NSAIDs and may be combined with them. See Librela for dogs for more detail.
  • Gabapentin: Sometimes used as an adjunct for chronic pain, particularly nerve-related discomfort.
  • Adequan (polysulfated glycosaminoglycan): An injectable disease-modifying drug that may help protect cartilage, though evidence is mixed. See Adequan vs Librela for a comparison.

Joint Supplements

Glucosamine, chondroitin sulfate, omega-3 fatty acids (EPA/DHA), and green-lipped mussel extract are widely used. Evidence quality varies, but omega-3 fatty acids at therapeutic doses have the strongest support for reducing joint inflammation.

Cold Laser Therapy and Other Modalities

Photobiomodulation (cold laser) may provide short-term pain relief and improved mobility in some dogs. It is non-invasive but requires ongoing treatments.

The Decision Framework

Whether to pursue surgery, medical management, or both depends on several factors:

  • Age and stage: Young dogs with laxity but minimal arthritis may benefit from preventive procedures (JPS, DPO/TPO). Older dogs with established arthritis are candidates for THR, FHO, or medical management.
  • Severity of signs: A dog that is painful despite appropriate medical management is a stronger surgical candidate than one that is comfortable with medication and lifestyle changes.
  • Body weight: THR is the best functional option for large and active dogs. FHO outcomes are less predictable in dogs over 60 lbs.
  • Financial considerations: Surgical costs are significant. Medical management is ongoing. Some owners can manage long-term medication costs more readily than a single large surgical expense.
  • Owner commitment: Post-surgical recovery requires strict activity restriction, rehabilitation exercises, and multiple follow-up visits.

What to Ask Your Veterinarian

  • Is my dog's lameness definitely from hip dysplasia, or could other joints be involved?
  • What stage is the disease — is there significant arthritis already?
  • Would my dog benefit from PennHIP evaluation or referral to an orthopedic surgeon?
  • What are the surgical and non-surgical options for my dog's specific situation?
  • What are the expected costs — including surgery, follow-up, and long-term management?
  • How will we know if medical management is no longer sufficient?
  • Are there clinical trials or specialty referral options available?
