Hatha yoga is a moderately-paced, catch-all name for the vast menu of poses that are practiced wherever you can roll out a sticky mat.
An 1100 lb horse on a dry forage diet at an average temperature of 68 degrees Fahrenheit will need a minimum of 6-7 gallons of water per day or 48-56 lbs of water, and many horses will drink more water than the minimum.
The water should be clean and fresh. An average size horse not in production will drink 10-12 gallons of water per day. In hot, humid weather, this amount could easily double. In fact, nursing mares often drink 20-25 gallons of water daily. It is just as important for horses to have adequate water intake in the winter.
