Canine Hip Dysplasia

Developmental dysplasia of the hip (DDH)

A common inherited orthopedic condition where the hip joint develops abnormally, causing pain, lameness, and eventually arthritis. Most common in large breed dogs.

Symptoms & Signs

Hind limb lameness

Limping or favoring one or both back legs, often worse after exercise or first thing in the morning.

Very common

Difficulty rising

Struggling to stand up from a lying or sitting position, especially on slippery floors.

Very common

Bunny hopping gait

Both hind legs move together when running instead of alternating.

Very common

Muscle atrophy in hindquarters

Loss of muscle mass making hip bones appear more prominent.

Sometimes occurs

Reluctance to exercise

Dog shows decreased interest in walks, play, or climbing stairs.

Very common

Behavioral Changes to Watch For

Pets can't tell us what's wrong. These behavioral changes are often the first clues that something is wrong.

ðŸū Decreased activity and playfulness

The dog stops initiating play and lies down during walks.

What You May Notice:

Your dog refuses to go up stairs they previously managed easily and lies down after short walks.

ðŸū Irritability when touched near hips

The dog may growl or snap when the hip area is touched due to chronic pain.

What You May Notice:

Your dog flinches or turns their head sharply when you pet their lower back or hips.

ðŸū Abnormal sitting posture

The dog sits with one leg splayed out to the side ("lazy sit") to reduce hip pressure.

What You May Notice:

Your dog consistently sits with legs off to one side rather than squarely.

Causes & Risk Factors

Causes

  • â€ĒGenetic predisposition (hereditary condition)
  • â€ĒAbnormal joint laxity during skeletal development
  • â€ĒRapid growth rate in large-breed puppies
  • â€ĒExcessive calcium intake during growth
  • â€ĒObesity putting extra stress on developing joints

Risk Factors

  • ⚠Large/giant breeds: German Shepherd, Labrador, Golden Retriever, Rottweiler, Great Dane
  • ⚠Rapid weight gain during puppyhood
  • ⚠High-calorie diet during growth phase
  • ⚠Excessive high-impact exercise in young dogs
  • ⚠Neutering before skeletal maturity may increase risk in some breeds

How It's Diagnosed

  • 1Physical examination: Ortolani test, Barden test for joint laxity
  • 2Hip-extended radiography (X-rays) under sedation/anesthesia
  • 3PennHIP radiographic method for early detection (as young as 16 weeks)
  • 4CT scan in complex cases for surgical planning

Treatment Options

lifestyle

Weight Management

Maintaining lean body weight is the single most impactful non-surgical intervention.

Steps

  1. 1.Calculate ideal body weight with your veterinarian
  2. 2.Feed measured portions of a balanced diet
  3. 3.Target body condition score (BCS) of 4-5/9
  4. 4.Low-impact exercise: swimming, leash walking on soft surfaces

Expected Outcome

Reduced joint stress, decreased pain, and slower progression of arthritis.

Precautions

  • !Rapid weight loss can cause other health issues
  • !Consult your vet before starting any weight loss program
medication

NSAIDs for Pain & Inflammation

Non-steroidal anti-inflammatory drugs to manage chronic pain.

Steps

  1. 1.Carprofen (Rimadyl) — most commonly prescribed
  2. 2.Meloxicam (Metacam) — alternative NSAID
  3. 3.Grapiprant (Galliprant) — newer option with potentially fewer GI side effects
  4. 4.Regular blood work every 6 months to monitor organ function

Expected Outcome

Significant pain reduction and improved mobility within days of starting.

Precautions

  • !Never give human NSAIDs (ibuprofen, naproxen) — they are TOXIC to dogs
  • !NSAIDs require a prescription and regular monitoring
  • !Watch for vomiting, diarrhea, or dark stools (signs of GI ulceration)
dietary

Joint Supplements

Nutraceuticals to support cartilage health and reduce inflammation.

Steps

  1. 1.Glucosamine + Chondroitin sulfate (Dasuquin, Cosequin)
  2. 2.Omega-3 fatty acids (fish oil) — anti-inflammatory at high doses
  3. 3.Green-lipped mussel extract
  4. 4.Adequan (PSGAG) injections — disease-modifying

Expected Outcome

Gradual improvement over 4-8 weeks as part of a multimodal approach.

Precautions

  • !Supplement quality varies — choose veterinary-formulated products
  • !Allow 6-8 weeks to evaluate effectiveness
procedure

Surgical Options

For severe dysplasia or dogs unresponsive to medical management.

Steps

  1. 1.Juvenile Pubic Symphysiodesis (JPS) — preventive, puppies 12-20 weeks
  2. 2.Triple Pelvic Osteotomy (TPO) — young dogs without arthritis
  3. 3.Femoral Head Ostectomy (FHO) — salvage procedure for any age
  4. 4.Total Hip Replacement (THR) — gold standard, restores near-normal function

Expected Outcome

THR provides excellent long-term outcome with 90%+ success rate.

Precautions

  • !Surgery is expensive ($3,000-$7,000 per hip for THR)
  • !Requires significant post-operative rehabilitation

Common Medications Used

MedicationUsageImportant Notes
Carprofen (Rimadyl)NSAID for chronic pain and inflammation managementGive with food. Monitor liver/kidney function every 6 months.
Adequan (PSGAG)Disease-modifying drug that supports cartilage repairGiven as intramuscular injection series. Can slow joint damage progression.

Prevention

  • ✓Choose a puppy from parents with good OFA or PennHIP hip scores
  • ✓Feed a large-breed puppy formula with controlled calcium levels
  • ✓Maintain lean body condition throughout life
  • ✓Avoid high-impact exercise in growing puppies
  • ✓Regular low-impact exercise to maintain supporting muscle mass

When to See a Veterinarian

  • ⚠ïļPuppy shows bunny-hopping gait or difficulty rising
  • ⚠ïļSudden worsening of lameness or non-weight-bearing on a leg
  • ⚠ïļSigns of pain despite current medications
  • ⚠ïļDecreased appetite or vomiting while on NSAIDs

Frequently Asked Questions

At what age do dogs show signs of hip dysplasia?
Signs can appear as early as 4-6 months in severely affected puppies, but many dogs don't show symptoms until middle age (5-8 years) when osteoarthritis develops.
Can hip dysplasia be cured without surgery?
It cannot be "cured" without surgery because the joint abnormality remains, but many dogs are managed successfully for years with weight control, NSAIDs, supplements, and physical therapy.

Prognosis

With proper multimodal management, most dogs live comfortable lives. Many will develop some degree of osteoarthritis over time. Early intervention significantly improves outcomes.
