Hi. I'm experienced dog owner who's never experienced this. I have a lab puppy-16 weeks old who's had chronic diarrhea since he's come home at 8 weeks. I first went the traditional route of rice and then pumpkin. It helped a little bit but he quickly started turning his nose up. Also, clearly rice doesn't have the nutrients puppies need. He's been tested for all the parasites and went through a round of panacur as a precaution. The vet has had him on metronidazole virtually his entire life.I have confidence in my vet but that makes me very nervous. I give him a probiotic (Flora Flora) in his food daily. Problem is, even on his poop is is formed but very soft. Off the meds, his poop totally loose. I've been researching and have seen some articles on EPI, but he doesn't seem to fit the bill because his weight gain is terrific and his coat looks great. Oh-and I read that bone broth is great for stomach issues, so I've even made that!
I've switched him from Fromms Puppy Gold to Canidae All Life Stages Lamb because it's a blander food with fewer ingredients. That hasn't helped and there I worry that again-he's not getting the puppy nutrition he needs (although the Life Stages is supposed to be complete for puppies).
Any thoughts? I don't know where to go next. Sorry for the long post.
