Working dogs including police, military, and assistance animals face unique challenges in pain recognition due to high drive and training suppression of pain expression.
The drive and training of working dogs creates a welfare paradox: the same dedication to work that makes these dogs effective may mask pain signals that would be obvious in a less motivated animal. A Belgian Malinois who is intensely motivated to complete a track or bite work may continue performing with significant hip pain that would cause a Labrador to stop and limp. The welfare obligation for handlers and organizations using working dogs is to implement proactive musculoskeletal assessment rather than relying on performance decline as the pain indicator, because by the time performance declines, significant suffering may have already occurred.
