Joint supplements are widely used for dogs with arthritis but scientific evidence for many products is limited. Understanding the evidence helps owners make informed choices.
Dogs with osteoarthritis experience chronic pain that reduces activity, quality of life, and lifespan. The supplement industry exploits owner concern with products of variable efficacy and quality. Using unproven supplements in place of evidence-based treatments may allow pain to continue unnecessarily. However, high-quality omega-3 supplements have genuine anti-inflammatory properties and can be useful adjuncts to comprehensive pain management. Veterinary anti-inflammatory medications (NSAIDs, grapiprant) and weight management provide the strongest evidence base for pain relief. A combination approach including appropriate medication, weight management, and exercise modification is optimal.
