After owning my calf horse for several years now, I would say that I know him well. About six months ago he started getting a little grouchy and would pin his ears when I rubbed his belly or put the cinch on. When I mentioned this to my daughter she told me that I should probably put him on Gastro Essentials and Digestive Essentials in case he was experiencing some upset stomach issues. After only 30 days of use, I noticed that Pooch was no longer unhappy and that he didn't back his ears or get grouchy when I saddled him. Whatever the reason or cause of his mood, John Ewing 707 products fixed him up. Thanks! Dale Motley
