rockstarinboots - 2016-02-04 1:27 PM I asked to assume it is not ulcers because I have treated this horse for ulcers. He did a month of gastro guard. Now he gets omeprazole before, during and after shows. He is on Forco and aloe. We treated him a year ago and been on this preventive protocol as recommended by his vet ever since. It still is not solving (even though a very logical explanation) to why he feels like crap after stress.
