Box rest is medically necessary for many horse conditions but carries significant psychological welfare risks requiring active management.
Box rest is a welfare paradox — necessary for physical recovery from serious conditions, but simultaneously damaging to psychological wellbeing. Horses unable to move, graze, or socialise freely experience profound frustration, stress, and in some cases the onset of new stereotypies. Welfare-centred box rest management actively mitigates these risks: multiple hay points extend foraging time; a companion in an adjacent stable provides social contact; graduated in-hand walking when medically permitted maintains some movement; and stable modifications that allow visual and tactile contact reduce isolation. Veterinary management plans should include explicit welfare measures for box rest periods, not just physical recovery protocols.
