Horse Isolation Welfare: Solitary Housing and Stress

Horses are social animals and solitary housing causes significant psychological distress that manifests in stereotypies, elevated stress hormones and abnormal behaviour.

Key Facts

Horses are obligate social animals that live in herd groups in the wild
Solitary-housed horses show elevated cortisol and behavioural signs of stress
Stereotypies including box walking, weaving and cribbing are more prevalent in isolated horses
Allowing visual and tactile contact with neighbours reduces some stress responses
Social isolation is a recognised welfare concern in the Horse Welfare Code in the UK

Welfare Considerations

Solitary housing is one of the most significant preventable welfare harms for horses and ponies. Where full social housing is not possible, allowing at least visual and tactile contact with neighbouring horses substantially reduces stress. Companion animals such as goats have been used to reduce isolation stress but are not equivalent to equine companions.

What You Can Do

Ensure horses are kept with or can see equine companions at all times
If solo housing is unavoidable, provide at least visual contact with other horses
Consider companion animals when multiple horses cannot be kept
Advocate for minimum social contact requirements in horse welfare legislation
