We often offer our horses water with molasses stirred into it. Sometimes you can find bags of dry molasses, which will keep a long time, and are less messy. (You can also by the liquid molasses at the grocery store.) Whenever we need to hydrate a horse, that’s what we turn to. If you try this at home, and get your horse accustomed to the taste, your picky drinker may turn into a guzzler….even away from home! Hope this helps.
