Horse Stereotypies: Causes and Prevention

Repetitive behaviors in horses such as weaving, crib-biting, and box walking indicate chronic stress and unmet behavioral needs.

Key Facts

10-15% of stabled horses develop stereotypies
Stereotypies are associated with high concentrate diets and limited forage access
Once established, stereotypies are difficult to extinguish even when husbandry improves
Horses evolved to graze 16-18 hours daily with near-constant movement

Welfare Considerations

Stereotypies are considered coping mechanisms for stress rather than bad habits. Physical methods to prevent them mask the symptom without addressing the cause. Management changes addressing forage access, social contact, and exercise opportunity are more humane and effective.

What You Can Do

Provide ad libitum forage to reduce boredom and gastric ulcer risk
Ensure daily social contact with other horses whenever possible
Allow regular free movement in paddocks rather than continuous stabling
Avoid anti-weaving grilles and devices that prevent the behavior without reducing stress
