I have no help to offer, but I’m just following this threat pretty much for the heck of it. I have a form of IBS, (ironically, diarrhea is not involved, phew!) so I totally feel your doggie. The only things I’ve been told for mine is, obviously, to avoid certain foods, which it sounds like you’re already doing.
I guess you could say I might just have to try eating whatever kibble/supplements that’s helping your pooch out? LOL, not seriously.

Best wishes! 😀
