If the vet finds nothing, stop everything except the food for a few days and see if that helps. In a perfect world, you can’t give too many probiotics, however the probiotics have other things in them besides just probiotics. If he is sensitive to the other stuff in probiotics, or digestive enzymes, then taking him off of them for a few days should help. It may do nothing at all, but then you would know that they aren’t contributing to the problem. I would take him down to the normal dose of probiotics now anyway. By now he has got to have what his system can support in his system. Right now, I feel like straws is all we have to grasp at. Basically, this has been going on long enough that I feel like if you can think of something different to try, try it, just wait until after the next fecal check.
