Stereotypic behaviours like crib-biting, wind-sucking and weaving develop in response to inadequate management and are difficult to eliminate once established, making prevention critical.
Stereotypic behaviours in horses represent a welfare failure - they develop because the animal's needs have not been met, typically by insufficient forage, social isolation or excessive confinement. Prevention requires appropriate management from the earliest age: adequate forage access, social companions, sufficient turnout and environmental complexity. Once established, stereotypies are difficult or impossible to eliminate and attempts to physically prevent them (anti-weaving grilles, cribbing collars) cause additional distress by blocking a coping mechanism. The welfare focus should always be prevention through appropriate management rather than suppression of established stereotypies.
