My dog has had diarrhea for more than six months. Not really bad, just loose stools. I tried changing his food 3 different times, my Vet gave him antibiotics and a full workup, there was no cause. I finally decided it was normal for him, even though it would smear into his hair and get everywhere sometimes. A friend recommended this product and I started using it. The difference is amazing. Not just the diarrhea but his gas is less and he seems better overall. My vet is impressed and now thinks my dog has a food intolerance or an intestinal imbalance.
