Horses are highly social animals whose welfare is significantly improved by appropriate group housing that enables natural social behavior.
Individual horse housing is a pervasive welfare problem created by management convenience and human concern about injury risk. The welfare cost is high: horses are social animals who maintain complex relationships through constant small interactions — grooming, proximity, play, and mutual reassurance — that are impossible in individual stabling. The chronic social deprivation of isolated stabling contributes to stereotypies, aggression toward handlers, and chronic stress. The fear of injury from group housing is legitimate but manageable: appropriately matched groups with sufficient space, resources, and gradual introduction have acceptable injury rates that are far outweighed by the welfare benefits of normal social life.
