Osteoarthritis (OA) is the most common cause of chronic pain in dogs. It affects millions of dogs worldwide and significantly impairs their quality of life if not properly managed.
Osteoarthritis causes chronic, often significant pain that profoundly affects a dog's quality of life. Dogs in chronic pain may withdraw from social interaction, show aggression when touched in painful areas, stop engaging in play, and develop anxiety. Because dogs hide pain so effectively, OA is frequently undertreated. Validated pain assessment tools (e.g., Liverpool Osteoarthritis in Dogs scale, CBPI) help owners and veterinarians objectively track pain levels and treatment response. Weight management is arguably the most impactful intervention — every kilogram of excess weight significantly increases joint loading and pain. Multimodal pain management — combining medications, physiotherapy, environmental modification, and weight control — gives the best welfare outcomes.
