Dog Pain Recognition and Management

Dogs are experts at hiding pain — a prey-species survival trait that leads to significant under-recognition and under-treatment of pain in companion animals, causing avoidable suffering.

Key Facts

Dogs have evolved to mask pain as a survival mechanism — in the wild, showing weakness attracts predators
Studies show that veterinarians and owners consistently underestimate pain severity in dogs compared to validated assessment tools
Validated pain scales for dogs include the Glasgow Composite Measure Pain Scale (CMPS-SF) and the Canine Brief Pain Inventory
Behavioral indicators of pain include reduced activity, altered gait, changes in facial expression, vocalization, and social withdrawal
Dogs with chronic pain often show progressive behavioral changes rather than acute responses — owners may attribute these to aging
Multimodal pain management — combining NSAIDs, gabapentin, tramadol, and physical therapy — is more effective than single-drug approaches
Untreated chronic pain causes physiological sensitization (wind-up) that worsens over time, making early intervention critical

Welfare Considerations

Pain under-recognition in dogs represents a significant, widespread welfare failure. A dog that has slowed down, stops jumping on furniture, or becomes irritable when touched may be displaying the only visible signs of significant chronic pain — yet these changes are routinely attributed to aging or personality rather than a treatable medical condition. The Canine Brief Pain Inventory, which owners can complete, provides a structured way to assess functional impact of pain across daily activities. Veterinary use of validated pain scales at every examination improves detection. NSAIDs are highly effective for osteoarthritic pain when used safely with appropriate monitoring; gabapentin addresses neuropathic pain components; physical rehabilitation strengthens supporting musculature. The welfare imperative is clear: untreated pain is neither inevitable nor acceptable.

What You Can Do

Complete a Canine Brief Pain Inventory (freely available online) if you suspect your dog has chronic pain
Request that your vet use a validated pain scale at every examination, particularly for senior dogs
Do not dismiss behavioral changes in older dogs as normal aging — investigate for treatable pain conditions
Ask about multimodal pain management if NSAIDs alone are insufficient — gabapentin, physical therapy, and environmental modifications all add value
Advocate for pain assessment to be a standard component of all veterinary wellness examinations
