Stereotypic behaviors in horses — repetitive, functionless movements — are indicators of compromised welfare and chronic stress. Understanding their causes is the first step toward prevention and management.
Equine stereotypies are welfare markers — their presence indicates that an individual's needs are not being met. They emerge as maladaptive responses to environments that deny natural behavior, particularly social contact, movement, and continuous forage access. Physical prevention devices (cribbing collars, anti-weave bars) cause additional welfare harm by blocking the coping behavior without addressing the underlying cause. Best welfare practice focuses on prevention through maximizing turnout time, providing ad libitum forage, enabling social contact through open stable doors or paddock companions, and minimizing stabling periods — particularly in young horses during sensitive developmental periods. Once established, management changes can reduce frequency but rarely eliminate stereotypies.
