I gave it to Fletcher with his food on a daily basis. It seemed to help prevent flare ups of his IBD. Because of the antibacterial properties of the honey? I don't know, but it worked. I see you did give the vet a fecal sample, it does sound like he may have something going on, maybe, I am not sure what the correct terms are, but there is an overgrowth of bad stuff in the intestines that can cause intermittent problems (sorry I can't be more specific!)
