Horse-companion animal bonds are strong and separation causes genuine distress that must be managed carefully to avoid welfare crises for both horses and their companions.
The strength of horse social bonds and the genuine welfare cost of separation are frequently underestimated by owners who view companion animals as interchangeable. A horse that has bonded to a companion animal experiences the removal of that companion as a significant welfare event — not a minor inconvenience. Management planning that accounts for companion bond strength and uses gradual separation or phased transition reduces the suffering associated with necessary separations.
