Have you ever been told to not allow a hot, sweaty horse to drink cold water because it could lead to colic, founder or tie up?
This notion is actually a myth, and a dangerous one too, because it could lead to dehydration and very serious (and real) consequences. A sweaty, hardworking horse needs to be rehydrated without delay (i.e. don’t wait for the horse to cool down first).
The key, however, is to know how much water to allow at one time — because of the equine stomach’s relatively small capacity, offer small amounts of water every 20 minutes until the horse drinks his fill rather than letting the animal drink it all at once.
Remember that water is the most vital nutrient for a horse. A horse’s daily water requirements are influenced by many factors, but the average idle 1,100-pound horse in a cool environment will drink 6 to 10 gallons of water per day. That amount may easily double or triple in a hot environment! Therefore, it goes without saying that providing cool, clean water to your horses at all times is of paramount importance.
