The actual daily amount of water that most horses need to consume (at a minimum) to maintain body functions and remain properly hydrated is from a half gallon to a gallon per 100 pounds of body weight.
Dehydration occurs if a horse loses too much water from its body and does not replenish it, or if a horse just is not consuming enough water every day to meet its bodily needs. A 3 to 4 percent loss of body water will cause mild dehydration. Some horses will only drink five to six gallons of water per day, will eat normally and remain healthy. These horses are the exception; their kidneys have the ability to concentrate urine and recycle more of the water back into the body.
