    Whenever I ship my horse and he gets Ulcerguard, he shows up happy and relaxed. The times I have shipped without it have not gone nearly as well. Must have.

    I give this to my horse whenever we go to clinics or shows. He gets nervous and this keeps his manure solid and the trips go smoother for him.

    My Vet recommended I start a 26 year old Arabian Mare on Ulcergard. About 7 days later, she began to eat so much better! I continued to dose the mare according to the directions. The mare is doing fantastic after 3 weeks! Great product and easily affordable with Entirely Pets!! Thank you very much!!!

    We had to move our horses to a new stable. One, a retired thoroughbred, has had stomach surgery and stresses easily.

    Our vet suggested Ulcer Gard. We treated him before & after the trip. He did great. No problems!.

    Now if only EntirelyPets sold the generic omeprazole.....
