Horse Stereotypies: Understanding and Addressing Repetitive Behaviours

Stereotypic behaviours in horses including crib-biting, weaving, and box-walking are indicators of chronic stress and compromised welfare, arising from management systems that frustrate fundamental equine behavioural needs.

Key Facts

An estimated 5-15% of stabled horses develop stereotypic behaviours depending on management system
Crib-biting involves grasping a fixed object and gulping air, associated with gastric ulcer risk and stress
Weaving involves rhythmic side-to-side head movement and is linked to social isolation and confinement
Once established, stereotypies are extremely difficult to eliminate even when management improves
Anti-weave bars and cribbing collars suppress the behaviour without addressing the underlying welfare problem
Horses with stereotypies tend to have reduced access to forage, turnout, and social contact

Welfare Considerations

Stereotypies in horses are not bad habits or vice but welfare indicators: evidence that an animal has experienced conditions that caused chronic frustration of its behavioural needs. Horses are highly social animals evolved for continuous movement and grazing over large areas. Confinement in stables for 20-23 hours daily, limited forage access, and social isolation are the primary risk factors. The welfare response is not to prevent the behaviour physically but to address the management conditions that gave rise to it. Increasing turnout time, ad libitum forage, social contact, and environmental complexity reduces stereotypy development in horses that have not yet established the patterns.

What You Can Do

Provide horses with maximum possible turnout time, ad libitum forage access, and social contact
Avoid management practices known to increase stereotypy risk, particularly prolonged stable confinement
Never purchase equipment designed to suppress stereotypic behaviours without also addressing underlying causes
Support equine welfare research into management practices that prevent and reduce stereotypy development
