Osteoarthritis affects an estimated 20% of adult dogs and is a leading cause of chronic pain. Many cases are underdiagnosed and undertreated because dogs modify their behaviour to conceal pain.
Dogs with osteoarthritis experience daily pain that affects their enjoyment of exercise, play, and social interaction. The progressive nature of the condition means that without management, quality of life declines steadily. Because dogs modify their behaviour to conceal pain, owners often attribute reduced activity to normal ageing rather than treatable disease. Prolonged untreated pain causes sensitisation of pain pathways that makes the condition harder to manage over time. Early diagnosis and multimodal pain management, including weight control and physiotherapy, is the most welfare-effective approach.
