Dog Chronic Pain: Assessment Tools and Quality-of-Life Impact

How chronic pain in dogs differs from acute pain, how it can be assessed systematically and how it should be treated differently.

Key Facts

Chronic pain — lasting more than 3 months — affects an estimated 20% of the adult dog population at any given time
Osteoarthritis is the most common cause, affecting 80% of dogs over 8 years
Chronic pain causes maladaptive central sensitisation — the nervous system amplifies pain signals beyond the original injury
Behavioural signs of chronic pain include reduced activity, altered gait, altered social behaviour and changes in sleep posture
Multimodal analgesia combining NSAIDs, gabapentin and physical therapy outperforms single-agent approaches
Bedinvetmab (Librela) — a monthly monoclonal antibody against nerve growth factor — offers a new mechanism for osteoarthritis pain

Welfare Considerations

Chronic pain in dogs is a welfare condition that is systematically under-recognised and under-treated in companion animal medicine. The absence of overt pain behaviours such as vocalisation or guarding does not indicate the absence of pain — it indicates that the animal has adapted behaviourally to a chronic pain state, modifying its activities to avoid pain-provoking movement and withdrawing from activities that it can no longer perform comfortably. Owners frequently attribute these changes to normal ageing rather than pain. Validated owner questionnaire tools such as the Helsinki Chronic Pain Index and the Canine Brief Pain Inventory provide objective frameworks for identifying and tracking chronic pain that do not depend on the owner recognising what they are observing as pain-related.

What You Can Do

Complete a validated chronic pain questionnaire for any dog showing reduced activity, reluctance to climb stairs or altered gait
Ask your vet explicitly about chronic pain management at every annual check for dogs over 7 years of age
Discuss multimodal analgesia — the combination of an NSAID, gabapentin and physical therapy produces better outcomes than NSAIDs alone
Ask about Librela (bedinvetmab) as a monthly injection option if your dog resists daily tablet administration
Implement environmental modifications: ramps to furniture and cars, non-slip flooring, raised food bowls for larger dogs
Reassess pain scores monthly and adjust treatment — chronic pain management requires ongoing monitoring, not a set-and-forget approach
