Thank you for sharing your feedback with us! Loose stools and diarrhea can definitely happen when transitioning to a fresh food like Happy Howl, as a pup's system needs time to adjust to such dense, rich ingredients. However, at the end of the day, it is all about what keeps your dogs happy and feeling their best! We are just glad you found a food like Pet's Table that works for your picky pups and supports their digestion. Thank you for giving us a try, and we wish your pack all the best!
