Keep the stable dry and draught-free with deep bedding and good muck management, but never seal it up, as ventilation prevents respiratory problems. Rug the horse to suit, and rely on forage and shelter more than a warm building.
Warmth comes from the horse, not the box
Horses generate heat by digesting forage, so plenty of hay does more to keep a horse warm than a snug building. Feed extra forage in cold snaps, ideally in a slow feeder so it lasts through the night and the gut keeps working.
Stop draughts, keep ventilation
Block cold draughts at horse height, but never seal the stable, since fresh air is vital for the lungs. A stable that is stuffy and damp causes far more harm than a cold, airy one. Aim for a dry, draught-free space that still breathes.
Bed deep and dry
A deep, dry bed insulates against the cold floor and encourages the horse to lie down and rest. Muck out well and keep the bed dry, since a wet bed chills the horse and raises ammonia that damages the airways.
Rug to suit the horse
Rug clipped, old, thin or unwell horses appropriately, and check under the rug that they are warm without sweating. A healthy, unclipped horse may need little or no rug even in a cold stable. Feel the horse rather than dressing it for how cold you feel.
Do not over-stable
Even a warm stable is no substitute for turnout and movement, which keep a horse healthy in body and mind. Get horses out daily where you can, and rely on shelter, forage and rugs rather than shutting a horse in a sealed, stuffy box.
