I’m coming to this late but your lab/bulldog sounds a lot like my pug. I don’t know about the digestive enzymes, but she can’t eat any dry food. I tried many different brands, including Rx for sensitive stomachs, alternative proteins, etc, and nothing worked. She had pneumonia when she was about 4 mos old and was on a lot of antibiotics (she almost died) and we think that messed up her whole system and gave her c-diff and chronic diarrhea. She’s 3 now and she can eat ONE kind of canned food. It took almost 2 years to figure out which food worked. She also takes Tylan powder, just a tad every other day. That saved her life, I think.
