Stereotypic behaviors in horses including crib-biting, weaving, and box-walking indicate underlying welfare problems typically caused by inadequate social contact, forage, and exercise, and require addressing root causes rather than suppressing symptoms.
Equine stereotypies are indicators of chronic welfare compromise, typically developing when horses are managed in ways that prevent expression of natural behaviors including continuous grazing, social interaction, and free movement. The development of a stereotypy represents a coping mechanism for psychological stress. Anti-weaving grids, cribbing collars, and other devices that prevent stereotypy performance without addressing the cause are counterproductive and may increase stress. Welfare-focused management includes ad-lib forage, social companionship, and maximum turnout.
