Chronic Pain Assessment and Management in Dogs

Chronic pain in dogs is frequently underdetected because dogs mask signs of pain as a survival instinct, and many owners mistake pain-related behaviour changes for normal aging.

Key Facts

Osteoarthritis affects an estimated 20% of dogs over one year of age and up to 80% of dogs over eight years
Dogs rarely vocalise chronic pain, instead showing subtle signs such as reluctance to rise, reduced play, and altered gait
The Canine Brief Pain Inventory and Helsinki Chronic Pain Index are validated owner-completed pain assessment tools
Gait analysis using pressure-sensitive walkways can quantify limb loading objectively in clinical settings
Multimodal pain management combining NSAIDs, gabapentinoids, and environmental modification improves outcomes
Anti-NGF monoclonal antibodies (such as bedinvetmab) offer monthly injectable options for osteoarthritis pain
Weight management is one of the most effective interventions for reducing joint pain in overweight dogs
Acupuncture, physiotherapy, and hydrotherapy provide adjunct benefit in some patients with chronic musculoskeletal pain

Welfare Considerations

Chronic pain profoundly reduces quality of life and is considered one of the most significant welfare challenges in companion animal medicine. Because dogs evolved to suppress pain signals in the presence of humans, even attentive owners often miss early signs. Veterinary education increasingly emphasises structured pain scoring at every consultation, not just post-surgical visits. Owner education — helping people recognise the difference between "slowing down with age" and pain-related behavioural change — is a high-impact intervention. Effective analgesia not only reduces suffering but restores engagement with activities the dog values, such as playing, exploring, and social interaction, significantly improving welfare outcomes.

What You Can Do

Learn to recognise subtle signs of chronic pain in dogs: reluctance to rise, reduced activity, changed temperament
Ask your vet to conduct a structured pain assessment at every senior dog check-up
Maintain your dog at a healthy weight to reduce joint load and slow arthritis progression
Discuss multimodal pain management options including newer anti-NGF therapies with your veterinarian
Support organisations funding veterinary pain research and owner education initiatives
