Box rest - confining an injured horse to a stable - is often medically necessary but creates significant welfare challenges that require active management.
Box rest imposes a profound welfare burden on an animal physiologically adapted to near-constant movement. The metabolic consequences of inactivity, the psychological consequences of social isolation and environmental restriction, and the behavioral consequences of inability to express normal locomotor behavior all accumulate over the duration of confinement. Horses on extended box rest frequently develop stereotypies that begin during this period. The gastrointestinal system, designed for near-continuous small-volume intake while moving, is disrupted by confinement and large meal feeding. Managing box rest as a welfare-positive experience rather than purely a medical instruction requires proactive enrichment, social contact, and veterinary guidance on safe movement opportunities.
