Horse Stereotypies: Understanding and Managing Repetitive Behaviours

Stereotypic behaviours in horses including crib-biting, weaving, and box walking indicate chronic stress and thwarted motivations, requiring management approaches that address underlying causes rather than just symptoms.

Key Facts

Stereotypies affect approximately 5-10% of domestic horses in the UK and are more common in stabled horses
Common stereotypies include crib-biting (grasping surfaces and gulping air), weaving, and box walking
Once established, stereotypies cannot be eliminated but their frequency can be reduced by improving management
Anti-crib-biting collars prevent the behaviour without addressing the underlying motivation, causing frustration
High concentrate feeding, long periods of stabling, and social isolation are major risk factors

Welfare Considerations

Stereotypies are outward signs of chronic welfare problems: horses performing repetitive behaviours are in a state of sustained motivational frustration. The behaviour itself provides some relief (hence its persistence) but does not address the underlying cause. Restricting the behaviour without addressing its cause causes additional frustration. The most effective approach improves management to address the factors that caused the stereotypy: increasing turnout, social contact, forage availability, and reducing high-concentrate feeding. Prevention through appropriate management from the start is far easier than management once established.

What You Can Do

Maximise turnout time and social contact to reduce stereotypy risk
Provide ad libitum forage (hay or grass) to satisfy foraging motivation
Avoid anti-weaving grids or crib-biting collars that prevent behaviour without addressing cause
If your horse has a stereotypy, work with an equine behaviourist to improve management
Do not discriminate against horses with stereotypies when buying or selling - address the cause
