Chronic Pain Management in Dogs: Recognizing and Treating an Underdiagnosed Problem

Chronic pain in dogs — from osteoarthritis, cancer, dental disease, spinal disorders, and other conditions — is pervasive but often underrecognized and undertreated, significantly impairing quality of life for millions of dogs whose stoicism masks their suffering.

Key Facts

Osteoarthritis is estimated to affect 20% of dogs over one year old and up to 80% of dogs over eight years old
Dogs are evolutionarily primed to hide pain as a survival strategy — clinical signs of chronic pain are subtle and easily attributed to normal aging
Pain assessment in dogs relies on behavioral indicators including reduced activity, altered gait, changes in temperament, and reluctance to perform certain movements
Validated chronic pain assessment tools including the Helsinki Chronic Pain Index and the Canine Brief Pain Inventory help owners and vets quantify pain levels
NSAIDs (non-steroidal anti-inflammatory drugs) are the mainstay of chronic pain treatment and are highly effective when dosed correctly and monitored for side effects
Multimodal pain management — combining NSAIDs, gabapentin, physical therapy, acupuncture, and weight management — provides better outcomes than any single intervention
The approval of monoclonal antibody treatments targeting nerve growth factor (similar to those used in humans) represents a significant advance in chronic pain management for dogs

Welfare Considerations

Chronic pain is one of the most significant and underaddressed welfare problems in companion dogs. The stoic nature of dogs means that owners frequently interpret reduced activity, reluctance to exercise, or behavior changes as signs of aging rather than pain. A dog who no longer rushes to greet visitors at the door, who hesitates at stairs, who spends more time lying down, may be living with chronic pain that is both identifiable and treatable. The ethical obligation of dog ownership includes proactive pain monitoring — not waiting for obvious lameness or vocalization before considering pain assessment. The good news is that effective treatments exist and can dramatically restore quality of life to animals whose chronic pain has been normalized.

What You Can Do

Use validated pain assessment tools such as the Helsinki Chronic Pain Index regularly to monitor your dog's comfort levels
Seek veterinary assessment if your dog shows reduced activity, reluctance to play or exercise, stiffness after rest, or behavior changes — these are pain signs
Discuss multimodal pain management with your vet rather than accepting a single medication as the ceiling of treatment options
Maintain healthy body weight in your dog — obesity dramatically increases joint pain and is one of the most impactful welfare interventions
Consider physical rehabilitation — hydrotherapy, therapeutic exercise, massage — as adjuncts to medication for chronic pain management
Advocate for routine chronic pain screening as part of annual wellness examinations for all dogs over seven years old
