I had the same problem with my horse, Bullet. When the vet told me that it was ulcer...I just could not believe it. I was so worried for Bullet..he was nevous, down right a grouch, not eating and at time he would roll himself in the barn. Literlly he seemed in pain. Since I am on a fix budget, I called my friend (he is a trainer for the last 40 years), he recommended a product that he has been using for the last 6 years on all his horses. U-guard (not U-guard pallet or U-Gard, had problems with that, it is a 8oz liquid bottle) that I got from Big Dee's for I believe $69.99 for 30 day treatment.I also have bought it online at uguardusa.com Bullet really got well very quickly, he started to perform well, began to eat normally, and his coat got really nice. I highly recommend it..it really works...I am trying to pass the word since I know many like me do not have the resources to pay name brand prices.
