Dog Osteoarthritis: Chronic Pain Management and Quality of Life

Osteoarthritis is the most common source of chronic pain in dogs, yet it is significantly underdiagnosed and undertreated. Understanding its management is essential for maintaining quality of life in older and large-breed dogs.

Key Facts

Osteoarthritis (OA) affects an estimated 20% of dogs over one year of age and over 80% of dogs over 8 years old
It involves progressive joint cartilage degradation, synovial inflammation, and bone remodelling causing chronic pain and stiffness
Dogs mask pain through adaptation — owners frequently attribute reduced activity to "slowing down with age" rather than pain
Validated pain assessment tools such as the Liverpool Osteoarthritis in Dogs (LOAD) and Canine Brief Pain Inventory (CBPI) help quantify impairment
NSAIDs are the first-line treatment but require regular renal and hepatic monitoring for long-term safety
Multimodal management — combining NSAIDs, physiotherapy, joint supplements, weight management, and environmental adaptation — produces better outcomes than single-modality treatment
Monoclonal antibody therapies targeting nerve growth factor (such as bedinvetmab) represent a significant recent advance in OA pain management

Welfare Considerations

Canine OA causes chronic pain that is pervasive, progressive, and systematically underrecognised. The subtlety of pain expression in dogs — reduced activity, reluctance to climb stairs, stiffness after rest, irritability when touched — allows owners to live with a chronically painful dog for years without recognising the extent of suffering. Quality of life assessments using validated tools provide concrete measures of impairment that help owners appreciate the degree of discomfort their dog experiences. Effective pain management restores activity and engagement with life; many dogs show striking quality of life improvements after appropriate treatment initiation. The welfare case for proactive OA screening in older dogs and large breeds, and prompt multimodal pain management, is overwhelming given the prevalence and treatability of the condition.

What You Can Do

Have dogs over 8 years old and large breeds over 5 years assessed annually for early OA signs
Use a validated quality of life assessment tool to track your dog's mobility and comfort over time
Start multimodal OA management early: physiotherapy, weight management, joint supplements, and NSAIDs as indicated
Ask your vet about newer pain management options including monoclonal antibody injections for OA pain
Adapt your home environment with ramps, raised food bowls, and orthopedic bedding to reduce daily discomfort
