Box rest — confining a horse to a stable for weeks or months — is often necessary for injury recovery but creates significant behavioral welfare challenges.
Box rest is genuinely distressing for horses — a prey species whose behavioral programming prioritizes movement, social contact, and environmental scanning. Prolonged solitary confinement causes stereotypies (weaving, box walking), gastric ulcers from stress, and muscle atrophy. Welfare-conscious box rest management includes providing a companion animal (a calm horse or goat visible nearby), maximizing sensory stimulation (views, smells, sounds), providing continuous forage to extend feeding time, and progressing to hand-walking as soon as the vet permits.
