Stable Vices in Horses: Causes and Welfare Implications

Stable vices including crib-biting, weaving, box-walking and wind-sucking are stereotypic behaviours indicating chronic frustration or stress, and their presence signals an unmet welfare need rather than a simple bad habit.

Key Facts

Stereotypic behaviours in horses are associated with restricted turnout, social isolation and low forage intake
Once established, stereotypies cannot be eliminated even if the underlying cause is resolved
Anti-weave grilles and crib collars suppress the behaviour without addressing the underlying welfare deficit
Horses with stereotypies had the behaviour induced by management and are not intrinsically flawed

Welfare Considerations

Stable vices represent welfare compromise that has become embedded in the horse's behavioural repertoire. Management approaches that suppress the behaviour without addressing its causes (inadequate forage, social isolation, restricted movement) perpetuate the underlying stress. The ethical approach requires identifying and addressing causative welfare deficits, not suppression.

What You Can Do

Provide ad-libitum or high-frequency access to forage to reduce oral frustration
Maximise daily turnout time and provide social contact with compatible horses
Never use anti-weave grilles or crib collars as a primary management strategy without addressing the cause
Consult an equine behaviourist if stereotypic behaviour is present to identify underlying welfare deficits
