My Maggie-Mae had bloody stool about a few years ago. It was during one of the few snows that Charlotte NC gets and the red on the white snow freaked me out. The vet didn't find anything wrong with her and basically said the same thing, inflammed intestine. She put her on something that coats the stomach and intestines so that she has time to heal without irritation. It was called Sucralfate and also Sufasalazine.
keep us posted on Trooper and how he is doing. Good wishes being sent your way.
