Imagine what cold water can do to hot muscles, cramping is not very pleasant. If the wind is howling, I will either scrape and towel him, or walk him a bit more to make sure that he does not cramp or chill. Then he is free to go roll in the sand. The best part about the desert as far as my horses are concerned is the availability of sandy spots to roll and sleep. Now, while I have been wetting him, he has been making sure that I get wet too, so we both cool at the same rate.
Horses are very kind that way.
Remember to spray him down with the Fly Away after his roll. All that sweat and water will have washed it off. Those of you who have white faced horses might want to put some sunscreen on the pink skin of the nose, horses sunburn too you know. Summer with your horse can be the best time of year. Just remember to take care of each other and you can enjoy even the hottest of days.
