Dog Chronic Pain Recognition: Behavioral Signs and Assessment

Chronic pain in dogs is systematically underrecognized and undertreated because dogs mask pain and owners misattribute behavioral changes to aging, making pain assessment tools critical welfare aids.

Key Facts

An estimated 20% of dogs suffer from osteoarthritis, with most cases inadequately treated
Validated pain scales including the Glasgow Composite Measure Pain Scale enable objective assessment
Behavioral signs of chronic pain include reduced activity, altered sleep, reluctance to jump or climb stairs
Non-steroidal anti-inflammatory drugs provide effective pain relief when appropriately prescribed and monitored
Multimodal pain management including physiotherapy, acupuncture, and weight management improves outcomes

Welfare Considerations

Chronic pain in dogs represents one of the most significant and widespread causes of reduced welfare in companion animals. The failure to recognize and treat it stems from dogs' survival-adaptive pain masking and owners' tendency to normalize aging-related behavioral changes. A dog who no longer greets owners at the door, hesitates before jumping onto furniture, or sleeps more than previously may be in chronic pain rather than simply aging. Validated behavioral pain assessment tools give owners and veterinarians an objective framework for identifying and monitoring pain that subjective impression misses. The welfare improvement from appropriate chronic pain management is substantial.
