No Sweat!"This is Bean' 2.5 year old tb mare, off the track in September very short race career, good weight very pleasant to work with, but would not go forward during?ground work, not naughty or nervous just completely shut down and saturated with sweat- dripping. Gave her a very generous amount of Comfort gut twice a day for a couple of days then tried again. Wow no sweat and very willing to move forward. Comfort gut has again proven its value" Cheryl Zdolski
