Dog Total Hip Replacement: Welfare Outcomes and Decision Making

Total hip replacement (THR) offers the best long-term functional outcome for dogs with severe hip disease. Understanding the procedure helps owners make welfare-centered decisions.

Key Facts

Total hip replacement in dogs has a 90-95% success rate and provides near-normal function in most patients
THR is most appropriate for dogs with severe hip dysplasia or femoral head necrosis unresponsive to medical management
The procedure replaces the femoral head and acetabulum with metal and plastic implants
Post-operative complications including infection, luxation, and implant failure occur in 5-10% of cases
Younger, heavier dogs achieve the best outcomes from total hip replacement
Recovery requires 8-12 weeks of restricted activity before gradual return to normal exercise
Femoral head and neck ostectomy (FHNO) is a salvage alternative but does not achieve the same functional result

Welfare Considerations

Total hip replacement dramatically transforms the welfare of dogs with severe hip disease who have exhausted medical management options. Dogs with uncontrolled hip pain experience chronic suffering with every step and lose the ability to participate in activities fundamental to their quality of life. THR restores near-normal joint mechanics and eliminates the arthritic pain driven by bone-on-bone contact. The welfare benefit is sustained across the dog's remaining life rather than requiring ongoing medication management. The welfare calculation strongly favors surgical intervention when medical management fails to provide adequate pain control.

What You Can Do

Seek specialist veterinary orthopedic consultation when hip disease causes significant pain unresponsive to medication
Discuss total hip replacement versus femoral head ostectomy with a board-certified veterinary surgeon
Ensure the dog is in good general health and appropriate weight before elective orthopedic surgery
Plan for the 8-12 week recovery period including appropriate housing modifications and activity restriction
Work with a certified canine rehabilitation therapist post-operatively to optimize functional recovery
Monitor the contralateral hip as bilateral hip disease frequently requires bilateral surgery
Assess long-term quality of life improvements objectively using validated mobility questionnaires
