We were having weeks of issues with diarrhea due to a food change and I tried everything to get it to stop. I took him to the vet, boiled chicken and rice, put him back on his old food, mixed in pumpkin and he was still having really loose stools. On a whim, I saw this at the supermarket and decided to give it a try. Whatever is in it, and whatever isn't in it, seems to work wonderfully and within 24-36 hours, he was back to normal. Also, my dog loves this food. The old food sat there and when he was starved, he ate it, but really didn't like it. This food he is excited to eat. I highly recommend it!
