Dog Chronic Pain Assessment: Recognizing Subtle Signs and Improving Management

Chronic pain is significantly underdiagnosed in dogs because subtle behavioral changes are often attributed to aging rather than treatable pain conditions.

Key Facts

Chronic pain in dogs is most commonly associated with osteoarthritis, which affects approximately 20% of dogs over age 2
Dogs rarely vocalize chronic pain — owners and vets must rely on behavioral and mobility changes
Validated pain scales (e.g., Helsinki Chronic Pain Index, CBPI) help standardize assessment in clinical practice
Common subtle signs include reluctance to climb stairs, reduced play, changes in sleeping position, and irritability
Multimodal pain management — combining NSAIDs, rehabilitation, and weight management — is most effective
New monoclonal antibody treatments (anti-NGF) offer substantial pain relief for dogs with osteoarthritis

Welfare Considerations

Chronic pain is one of the most prevalent and underappreciated welfare problems in companion dogs. Because dogs evolved to hide weakness, they rarely signal pain overtly. Owners and veterinarians too often attribute slowing down and reduced activity to "just getting old" when the underlying cause is treatable pain. Undertreated chronic pain causes persistent suffering and progressive behavioral and personality changes. The development of validated pain assessment tools and new pharmacological options has transformed the ability to identify and manage chronic pain in dogs. Regular pain monitoring at veterinary visits should be standard practice for all dogs over seven years old, and owner education about subtle pain signs is essential.

What You Can Do

Learn the subtle signs of chronic pain in dogs: hesitation to rise, reduced grooming, changed sleep patterns
Raise pain concerns explicitly with your veterinarian at annual checkups — do not assume slowdown is just age
Ask about multimodal pain management options including physical rehabilitation and weight management
Discuss new anti-NGF antibody therapies with your veterinarian if your dog has osteoarthritis
Keep records of your dog's daily activity and behavior to track changes that may indicate pain progression
