Osteoarthritis is the most common cause of chronic pain in dogs, affecting an estimated 20% of the adult dog population, and 2025 has seen significant advances in both pharmaceutical and non-pharmacological management options.
Osteoarthritis causes chronic pain that fundamentally impairs a dog's ability to perform normal activities, rest comfortably, and maintain social engagement. Because dogs typically hide pain, the condition is severely underdiagnosed and undertreated. Recognition of subtle signs such as reduced activity, reluctance to jump, and behavioural changes is essential for timely intervention. The growing therapeutic toolkit available in 2025, including novel biologics, provides improved pain relief options, but owner and veterinary recognition of the condition remains the key welfare bottleneck.
