Stereotypic behaviors in horses including crib-biting and weaving signal poor welfare. Prevention through appropriate management is far more effective than suppression of established behaviors.
Equine stereotypies represent permanent behavioral scars from early management deprivation. Research consistently shows that horses develop stereotypies when management fails to meet fundamental behavioral needs: the foraging drive motivating up to 16 hours of daily movement and food seeking in wild horses is frustrated by stabling with twice-daily meal feeding; social bonds are severed by individual stabling; large-range movement needs are denied by small paddocks. Prevention is straightforward — maximize pasture and social access, provide ad libitum forage, and avoid prolonged stabling especially in young horses. Once a stereotypy is established, attempting to physically prevent the behavior through collars or surgery causes welfare harm without addressing the underlying deficit.
