The need for a blanket will depend on the weather conditions, type of trailer, and ventilation available. In a well-ventilated trailer on a warm day, you won't need to blanket your horse. In some cases, having a heavy blanket on the horse in a poorly ventilated trailer can cause horses to sweat and become overheated, even in cold weather. In general, don't over-blanket, and keep the air moving inside the trailer so your horse can have a comfortable ride.

It is also customary to wrap a horse's legs when trailering. Leg wraps that extend from the knee or hock to the coronary band can help protect your horse during a trailering trip. However, be sure you know how to properly apply leg wraps. They can cause injury and permanent damage when not applied properly.

Also make sure your horse has had time to get used to its legs being wrapped before being hauled in the trailer. Many times, horses will kick and stomp when first wearing leg wraps.
