It really is a great product. My girlfriend uses it on an Appendix bred horse that she has that is a real hard keeper in the summer. He can easily drop 2-300 lbs. But this year she has had him on this and he has done great. The best thing is it does not make him hot at all, and since you don't feed a lot of it, it makes it affordable. Good Luck and I hope it help give him the spark he needs.
