I find Oreo is now pretty sensitive to the stomach because early this morning he had a major poopie monster attack in his crate again. I caught him trying to clean it up AFTER he had already thrown it up, trying to clean it before!! Let's just say, it made my stomach turn. The only thing I can figure it was, was that my 2.5 yr old daughter dropped a piece of avocado, about 1", on the floor and he ate it. We did not give him anything other than that, so I think the cause of the upset was the avocado. Any suggestioins on helping him to firm up his stools? What do you do when you have has stomach upsets? Do havs have sensitive tummies?
