Dogs are stoic animals that mask pain effectively. Understanding pain recognition and management is critical for improving the welfare of dogs with musculoskeletal and other painful conditions.
Chronic pain in dogs represents a major and largely invisible welfare burden. Dogs evolved as prey animals to mask vulnerability — limping conspicuously in a predator-rich environment would be dangerous. This stoicism means that significant osteoarthritis, dental pain, and other chronic conditions can progress for months or years before owners recognize a problem. Studies using validated pain assessment tools reveal that dogs owners rate as "doing fine" frequently show multiple behavioral indicators of chronic pain on structured assessment. Owner education about subtle pain signs and regular veterinary assessment are the primary tools for detecting and treating hidden suffering.
