Is it true that horses don need to be given water in the winter because they can eat snow to stay hydrated?
No. Horses need to have water to drink every day. Snow is made up mostly of air so a horse would have to eat a whole bunch of snow to consume enough water to stay properly hydrated. Most horses drink more water in the winter because water acts as an anti-freeze and keeps the horse’s body temperature consistent. Generally, an average horse will drink about 10 gallons of water a day.
