Dog Hip Dysplasia

Hip dysplasia is one of the most common orthopedic conditions in dogs, affecting millions of pets worldwide. This page covers everything you need to know about recognizing, treating, and managing hip dysplasia to help your dog live a comfortable, active life.

What is Hip Dysplasia?

Hip dysplasia is a developmental condition where the hip joint doesn't form properly. In a healthy hip, the ball (femoral head) fits snugly into the socket (acetabulum). In dogs with hip dysplasia, the joint is loose and unstable, causing abnormal wear, inflammation, and eventually arthritis.

How Hip Dysplasia Develops

• Genetic predisposition: Dogs inherit the tendency to develop hip dysplasia
• Rapid growth: The joint develops abnormally during puppyhood
• Joint laxity: Looseness allows the bones to move abnormally
• Cartilage damage: Abnormal movement wears down protective cartilage
• Arthritis: Bone-on-bone contact leads to chronic inflammation and pain

Breeds Most Commonly Affected

While any dog can develop hip dysplasia, certain breeds are at higher risk.

High-Risk Breeds

• German Shepherd
• Labrador Retriever
• Golden Retriever
• Rottweiler
• Great Dane
• Saint Bernard
• Bulldog
• Mastiff breeds
• Old English Sheepdog
• Bernese Mountain Dog

Note: Small and medium breeds can also develop hip dysplasia, though it's less common and often less severe.

Symptoms of Hip Dysplasia

Symptoms can appear as early as 4 months of age in puppies or may not become apparent until a dog is older.

Early Signs (Puppies and Young Dogs)

• Bunny-hopping gait (using both back legs together)
• Reluctance to climb stairs or jump
• Difficulty rising from lying down
• Decreased activity or playfulness
• Swaying or wobbling when walking
• "Clicking" sound from the hip when walking

Later Signs (Adult and Senior Dogs)

• Stiffness, especially after rest
• Limping or lameness in back legs
• Muscle loss in back legs (atrophy)
• Enlarged shoulder muscles (compensating for weak hips)
• Reluctance to exercise
• Pain when touched around hips
• Decreased range of motion
• Difficulty getting up, lying down, or squatting to defecate

Primary Causes

• Genetics: The most significant factor; inherited from parents
• Rapid growth: Fast weight gain strains developing joints
• Improper nutrition: Excess calories and calcium during growth
• Over-exercise as puppy: High-impact activities before joints mature

Contributing Factors

• Obesity: Extra weight stresses joints and accelerates deterioration
• Muscle mass: Weak muscles provide less joint support
• Hormones: Early spay/neuter (consult AVMA guidelines on optimal timing) may affect bone development in some breeds
• Environment: Slippery floors, excessive jumping

Diagnosis

Accurate diagnosis requires veterinary examination and imaging.

Physical Examination

• Observing gait and movement
• Testing range of motion
• Checking for pain response
• Ortolani test (checking for joint laxity under sedation)
• Assessing muscle mass and symmetry

Imaging

• X-rays (radiographs): Standard diagnostic tool showing joint conformation
• OFA evaluation: Orthopedic Foundation for Animals hip certification
• PennHIP: Distraction radiography measuring joint laxity
• CT scan: For surgical planning in complex cases

Grading Systems

Treatment Options

Treatment depends on the severity of dysplasia, the dog's age, size, and overall health.

Conservative (Non-Surgical) Management

Often effective for mild to moderate cases and older dogs.

Weight Management

• Maintaining ideal body weight is crucial
• Every pound lost reduces stress on joints
• Work with your vet to determine ideal weight and diet

Exercise Modification

• Regular, low-impact exercise to maintain muscle mass
• Swimming is excellent (non-weight-bearing)
• Controlled leash walks on even surfaces
• Avoid high-impact activities (jumping, rough play)
• Underwater treadmill therapy

Medications

• NSAIDs: Carprofen (Rimadyl), meloxicam (Metacam), deracoxib (Deramaxx)
• Joint supplements: Glucosamine, chondroitin, MSM, omega-3 fatty acids
• Adequan injections: Injectable polysulfated glycosaminoglycan
• Pain medications: Gabapentin, tramadol for breakthrough pain

Physical Therapy

• Range of motion exercises
• Massage therapy
• Hydrotherapy
• Laser therapy
• Acupuncture

Surgical Options

Surgery may be recommended for severe cases or young dogs with significant joint laxity.

Juvenile Pubic Symphysiodesis (JPS)

• Age: Puppies 12-20 weeks old
• Procedure: Fuses part of the pelvis to improve hip coverage
• Best for: Early intervention in at-risk puppies
• Cost: $1,000-$3,000

Triple Pelvic Osteotomy (TPO)

• Age: Dogs under 10-12 months
• Procedure: Cuts and rotates the pelvis for better hip coverage
• Best for: Young dogs with laxity but no arthritis
• Cost: $2,500-$5,000 per hip

Femoral Head Ostectomy (FHO)

• Procedure: Removes the femoral head, creating a "false joint"
• Best for: Small to medium dogs, or when cost is a concern
• Recovery: Physical therapy essential for good outcome
• Cost: $1,500-$3,500 per hip

Total Hip Replacement (THR)

• Procedure: Replaces entire hip with prosthetic components
• Best for: Large dogs with severe dysplasia
• Success rate: 90-95% return to normal function
• Cost: $5,000-$7,500 per hip

Environmental Modifications

• Non-slip rugs or mats on hard floors
• Ramps instead of stairs
• Orthopedic or memory foam bed
• Raised food and water bowls
• Prevent jumping on/off furniture (use pet stairs)
• Keep nails trimmed for better traction

Daily Care Tips

• Warm compresses before exercise
• Cold compresses after exercise if inflamed
• Gentle massage of hip muscles
• Maintain consistent exercise routine
• Monitor for changes in mobility or pain

Prevention

While genetics play the largest role, these strategies can reduce risk and severity.

Before Getting a Puppy

• Choose breeders who screen parents for hip dysplasia (OFA or PennHIP certified)
• Ask to see hip clearances for both parents and grandparents
• Research breed-specific health testing recommendations

Puppy Care

• Feed appropriate large-breed puppy food (controlled calcium and calories)
• Avoid overfeeding - keep puppies lean
• Limit high-impact exercise until growth plates close (12-18 months)
• No forced running, jumping, or rough play on hard surfaces
• Provide non-slip flooring

Ongoing Prevention

• Maintain healthy weight throughout life
• Provide regular, appropriate exercise
• Consider joint supplements for at-risk breeds
• Regular veterinary check-ups

Prognosis

With proper management, most dogs with hip dysplasia can live comfortable, happy lives.

• Mild cases: Often managed well with conservative treatment
• Moderate cases: May require multimodal management but good quality of life achievable
• Severe cases: Surgery often provides excellent outcomes
• Key factors: Weight management, appropriate exercise, and pain control are essential
