Understanding natural horse social behaviour is essential for providing welfare-appropriate management that meets their social needs while preventing conflict and injury in managed groups.
Horse social needs are frequently compromised by management decisions driven by convenience, insurance concerns, or anthropomorphic assumptions about horse preference. Horses are not naturally solitary — keeping horses in isolation except for ridden work denies them the social bonds and affiliative behaviours that are fundamental to their wellbeing. The welfare-positive approach to horse social management starts from the premise that horses need compatible equine companionship, works to identify suitable companions, and invests in transition management when groups change. Where full group turnout is not possible, shared fencing that allows nose-to-nose contact and parallel grazing provides meaningful social contact. The minimal welfare standard — that no horse is kept in complete social isolation — should be universal.
