How many gallons of water does a healthy horse drink each day?

Answer 1:

In cool weather, horses will drink about 10-12 gallons per day. During hot weather they drink 20-25 gallons (or more) per day depending on the heat and humidity.

Answer 2:

A horse drinks roughly 1.5 to 1.0 gallons of water per 100 pounds of body weight. In the winter horses tend to drink less as they don't like to drink overly cold water and in the summer or during very hard work they may drink up to twice as much. There is no one 'standard' amount of water a horse will drink year round.
