Hi Tara-
Since you said he has bad gut bacteria, I’m assuming that you have had a fecal test done. It is common for a pup to get Coccidia and/or Giardia. Hopefully, those have been ruled out. I had a problem with loose stools with my dogs and feeding grain free Victor and adding probiotics, digestive enzyme and a supplement that contains slippery elm is very helpful. Victor is a budget friendly 5 star grain free food.
I feel like you need to figure out what is causing the diarrhea. Whether it be parasites, food intolerance or IBS, so you can fix the issue.
The dogaware.com website has a lot of great info on their digestive disorders thread. I wish you the best. It’s not a very fun issue!
