In this video, I show you how to put on a cooler (a light blanket used to keep a sweaty or wet horse warm while he dries off). You can do the same thing to put any kind of blanket on a horse. Blankets are very useful for lots of things, including keeping your horse warm and dry, keeping bugs off him or even keeping him from getting sunburned if he is a pink-skinned horse! Make sure that any blanket you put on a horse fits him properly and is correctly put on.
