How to Blanket a Horse in Cold Weather

Putting a blanket on a horse with a good winter coat is actually counter-productive. The weight of the blanket lays the hair down, eliminating the loft, the air layer of natural insulation. If you know what "hat hair" is – where your hair is pasted down by the weight of your hat – that is what a blanket does to a long-haired horse.

For horses with thin hair coats, you may need to remove the blanket and put on a sheet to keep them comfortable during the day if it warms up. The test is to have a heavy enough cover to keep the horse warm but never hot.

Many times it is good to dress horses like people do, in layers. It makes sense for stalled horses with slick coats to wear a sheet under a blanket. The blanket goes on and off as the temperature changes. If you have medium weight blankets and experience an unusually cold period you can add a light sheet over your blanket to tide you over until the weather moderates. Whenever possible, every horse should have part of each day free of blankets to let them exercise and air out.

What kinds of blankets are best?
