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.
Re: How many litres of water are you horses drinking each per day atm? A lot :S I would say 25% more than usual if that helps. I have a large plastic bucket, comes up just above my knees and is about 60cms wide (at a guess) and am having to refill every 24 hrs.
