Osteoarthritis in Dogs: Recognising and Managing Chronic Pain

Canine osteoarthritis affects millions of dogs worldwide and is a leading cause of chronic pain and reduced quality of life, yet remains significantly underdiagnosed and undertreated in veterinary practice.

Key Facts

Osteoarthritis affects approximately 20% of dogs over one year old and up to 80% of dogs over eight years
It involves progressive cartilage loss, synovial inflammation, bone remodelling, and osteophyte formation
Dogs are stoic and mask pain through behavioural adaptation, making owner recognition of lameness delayed by months or years
Validated tools including the Canine Brief Pain Inventory and Liverpool Osteoarthritis in Dogs scale enable objective monitoring
Multimodal management combining NSAIDs, physiotherapy, weight management, and environmental modification outperforms single-drug approaches
Novel therapies including anti-nerve growth factor antibodies (bedinvetmab, frunevetmab) offer additional pain control options
Obesity is the most modifiable risk factor — each kilogram of excess weight significantly accelerates joint deterioration

Welfare Considerations

Osteoarthritis causes chronic, progressive pain that fundamentally limits a dog's ability to engage in the activities that constitute canine quality of life — running, playing, social interaction, and exploration. The insidious nature of the condition means dogs adapt their behaviour to avoid pain, reducing activity levels in ways owners often attribute to normal ageing rather than treatable pain. By the time obvious lameness or reluctance to move is noticed, significant welfare compromise has often existed for months. Effective pain management restores activity levels and social engagement that owners describe as transformative. Veterinary management requires ongoing reassessment — arthritis is progressive, and treatment regimes that provided adequate control at one stage may be insufficient as disease advances. Weight management is particularly high-impact: even modest weight loss in obese dogs produces measurable improvement in pain and mobility. Environmental modifications including orthopaedic bedding, ramps for furniture access, and non-slip flooring reduce pain during daily activities at low cost.

What You Can Do

Have dogs assessed for joint disease annually from middle age using validated pain scoring tools
Maintain dogs at healthy body weight throughout life as the most powerful modifiable factor for joint health
Provide orthopaedic bedding, ramps, and non-slip surfaces for dogs with mobility limitations
Ask your veterinarian about multimodal pain management options rather than relying on a single medication
