Canine Osteoarthritis: Managing the Most Common Cause of Chronic Dog Pain

Osteoarthritis affects a large proportion of dogs and is a leading cause of chronic pain and reduced quality of life. Early detection and multimodal management make a significant difference to welfare.

Key Facts

Osteoarthritis is estimated to affect 20% of dogs over one year of age and up to 80% of dogs over eight years
The condition involves progressive cartilage degradation and joint inflammation causing chronic, often severe pain
Large and giant breeds, overweight dogs, and those with conformational abnormalities are at highest risk
Dogs rarely vocalise in response to chronic pain; instead they show reduced activity, reluctance to climb, and behavioural changes
The Liverpool Osteoarthritis in Dogs (LOAD) and Canine Brief Pain Inventory are validated owner assessment tools
NSAIDs including meloxicam and carprofen are the most commonly used analgesics for canine osteoarthritis
Anti-NGF monoclonal antibodies (bedinvetmab) represent a new class of treatment with strong efficacy evidence
Multimodal management combining analgesics, physiotherapy, weight management, and environmental modification achieves best outcomes

Welfare Considerations

Canine osteoarthritis is among the most common causes of chronic pain and reduced quality of life in companion dogs, yet it remains substantially underdiagnosed and undertreated. The tendency of dogs to adapt their behaviour to accommodate pain, combined with owner attribution of signs to normal ageing, means that many affected dogs spend years in unnecessary discomfort. Welfare-conscious management begins with proactive assessment: owners of middle-aged and older dogs, particularly large breeds, should routinely monitor for early signs and discuss preventive screening with their vets. Effective treatment exists and has expanded considerably with the availability of anti-NGF therapies; the challenge is ensuring that affected dogs receive appropriate care rather than simply being labelled as slowing down with age. Weight management is one of the highest-impact interventions available and within owner control.

What You Can Do

Monitor your dog for early signs of osteoarthritis including reduced jumping and stair reluctance
Maintain your dog at an optimal body weight as even modest weight loss significantly reduces joint load
Ask your vet about osteoarthritis screening at annual check-ups for dogs over five years
Discuss multimodal pain management options including NSAIDs and newer anti-NGF therapies with your vet
Implement environmental modifications including ramps, orthopedic bedding, and non-slip flooring
Consider hydrotherapy and physiotherapy as adjuncts to pharmaceutical pain management
Use validated owner questionnaires to monitor pain levels and treatment response over time
