Blowing bubbles in the water, runny manure, off feed, grinding teeth, dog sitting, any or all signs.
I had a colt a few years back that right after weaning developed terrible diarrhea and teeth grinding, blwing bubbles in his water. Treated him with omeprazole, sucralfate(carafate) for almost two months and he was fine.
This past November I had a beautiful filly that had a teeny bit of loose manure and was blowing bubbles in the water, nursing great but no interest in feed , nibbled hay and grass. Got her started on all the meds imediately, she perked up real nice later in the day but she died suddenly overnight.
Don't take ulcers lightly! I jumped on her right away and I still lost her.
