It is safe to give a horse two or three - sometimes even four - servings per day, depending on their age, condition, athletic needs, and heat and humidity conditions that are present. Even in cold weather, it is important to monitor water intake very carefully.If your horse has Cushings or some other metabolic condition which requires limited sugar intake, consider using our NO SUGAR ADDED formula. It has the same flavor and benefits as the Original formula, but without added sugar.Many people have their horses on a daily serving of Gallagher's Water as a type of hydration maintenance.As always, please consult with your Veterinarian before introducing new and different dietary feeds and supplements.
