Box rest is frequently prescribed for injured horses but causes significant psychological distress through confinement, social isolation, and behavioural restriction.
Box rest is a necessary welfare compromise for treating orthopaedic injuries, but its psychological costs are substantial and often underappreciated. Horses on strict box rest show marked increases in anxiety behaviours, social vocalisation, and stereotypies. The combination of physical restriction, social isolation, and boredom creates chronic stress that can compromise recovery and cause long-term behavioural changes. Strategies to minimise psychological harm while maintaining physical rest are critical for overall welfare outcomes.
