Heat and exercise can lead to severe problems with overheating and dehydration. Horses should be cooled after exercise. You should always walk for at least the last ten to fifteen minutes of your ride. Let the horse drink as much water as it needs to after removing your tack.
When he's finished drinking, hose him with running water, or sponge water over his body until the water runoff is no longer hot. Scrape off excess water then start walking the horse in a cool, shaded area. Placing a few fans in the area where you walk your horse may also be helpful. When the horse is hydrated and cooled down, then you can safely put him away.

After walking the horse for 10-15 minutes, you can quickly untack and then check the legs for cuts or swelling. Then, continue walking the horse until their temp. is normal again. You may put on a cooler or hose them off with cool water depending on the weather.
