Joint supplements are widely used for dogs with arthritis. Understanding the evidence base helps owners make informed decisions and avoid delays in pursuing proven treatments.
Arthritis causes chronic pain that profoundly affects dog quality of life, and the search for welfare improvement drives the large joint supplement market. The welfare risk of supplement-focused approaches is that owners may pursue unproven supplements while delaying proven treatments including veterinary-prescribed NSAIDs, weight management, and physical rehabilitation. Dogs in pain deserve effective analgesia rather than sole reliance on supplements with uncertain benefit. Supplements may play a supportive role alongside proven approaches, but the primary welfare responsibility is ensuring adequate pain management through evidence-based methods.
