Access to suitable shelter is a fundamental welfare requirement for horses and ponies kept outdoors, protecting them from weather extremes.
Outdoor horse welfare depends on suitable shelter being available and accessible to all horses in a group. Dominant hierarchy means that a single shelter with a narrow entrance may effectively deny access to subordinate horses during bad weather, causing hypothermia or heat stress. Natural shelter from hedgerows and trees supplements artificial shelters. Horses need protection from both cold wet weather and summer sun and fly pressure. Poached gateways and feeding areas cause mud-related foot problems during wet winters. Monitoring body condition during winter is essential for horses at grass, as rough coats mask weight loss. Water provision must never freeze without alternative access.
