Water is the most important nutrient, and horses can't live long without it. Make sure that you are monitoring your horses water intake and supplying a clean, fresh source of water. If your horse utilizes an automatic watering system, then check the waterer daily to ensure that it's supplying an adequate amount of clean water. If your horse depends on water buckets or tubs, then make sure that they are cleaned on a consistent basis and can offer enough water to get them through the day without going dry.
