Dog Joint Disease, Osteoarthritis, and Welfare

Osteoarthritis and other joint diseases cause chronic pain in millions of dogs, with significant welfare implications that are often inadequately recognised and treated.

Key Facts

Osteoarthritis affects an estimated 20% of dogs over one year of age; prevalence increases sharply with age.
Hip dysplasia, elbow dysplasia, and cruciate ligament disease are among the most common causes of canine joint disease.
Dogs mask pain effectively; many owners are unaware their dog has significant joint disease until it is advanced.
Behavioural signs of chronic pain include reluctance to exercise, difficulty rising, stiffness after rest, and reduced play.
Pain scoring tools for dogs include the Helsinki Chronic Pain Index and the Liverpool Osteoarthritis in Dogs (LOAD) scale.
Multimodal pain management combining NSAIDs, physiotherapy, and weight management is the standard of care.
Newer treatments including monoclonal antibodies targeting nerve growth factor (anti-NGF) show promising results in dogs.
Genetic selection in breeding has contributed to joint disease prevalence in many popular breeds; health testing can reduce it.

Welfare Considerations

Canine joint disease is a pervasive source of chronic pain that is systematically undertreated. Dogs evolved to hide pain as a survival mechanism, meaning owners often interpret reduced activity as normal ageing rather than a welfare problem requiring veterinary attention. The gap between the prevalence of joint disease and the proportion of dogs receiving adequate treatment represents a major collective welfare failure. Addressing it requires owner education about pain recognition, accessible veterinary care, better health testing requirements in breeding, and regulatory environments that make effective pain management available and affordable for all dog owners, not just those who can pay premium veterinary fees.

What You Can Do

Have your dog assessed for signs of joint pain at every annual veterinary check, especially from middle age onwards.
Learn the behavioural signs of chronic pain in dogs and act promptly if you observe them.
Maintain your dog at a healthy weight; obesity significantly worsens joint disease and pain.
Work with your vet to develop a multimodal pain management plan rather than accepting reduced activity as inevitable.
Choose puppies from breeders who health-test for hip and elbow dysplasia and publish their results.
