Pain recognition in horses is improved by validated assessment tools including grimace scales and behavioral indicators, though significant gaps between best practice and common application remain.
Horse pain recognition and management represents a welfare frontier where improved tools have not yet fully reached practice. The combination of horses' stoic nature — evolved to mask pain as prey animals — and the practical challenges of assessing pain in large animals contributes to systematic underestimation. Validated grimace scales provide more objective assessment, but require training and consistent application to be useful in practice. Chronic pain from conditions like laminitis and navicular disease is particularly concerning — horses with these conditions may live for years with significant untreated pain while continuing to be used for riding and competition. Cultural change within equestrian communities toward taking horse pain seriously is as important as the availability of diagnostic tools.
