The investigators’ recent comprehensive survey found that both veterinarians and members of the public believe that dog breeds differ in their sensitivity to pain, yet this has never been fully investigated. Beliefs about breed differences in pain sensitivity could negatively impact clinical recognition and treatment of pain in dogs and result in unnecessary pain, particularly for breeds viewed as less sensitive to pain. The investigators hypothesize that dogs have similar pain sensitivity thresholds, regardless of breed, but that human perceptions about breed-based differences in pain sensitivity affect the clinical recognition and treatment of pain. This study will endeavor to answer whether dog breeds differ in pain sensitivity, and whether breed affects veterinarians’ treatment of pain in dogs. If breed differences in pain sensitivity exist, future work would be performed to understand genetic associations, and advance our understanding of effectively treating pain in a breed-specific manner. If no differences exist, then the impact of the human perception of breed differences must be understood to ensure that dogs of every breed receive appropriate pain management.
