Some dogs may get digestive issues.
Well, it seems that my dogs digestive system could not tolerate Happy Howl. We transitioned him slowly per the instructions and when he got to the full diet of HH, he started getting sick. He started having mucousy poop with tinge of blood. This is indicative of intestinal inflammation. He also would vomit a bit intermittently. We stopped feeding HH and got him back on his previous food and he bounced right back. Im not saying that HH is a bad food but it does appear that not all dogs may tolerate it. My little guy is a chihuahua. For some reason he just couldn't tolerate it.

We are so incredibly sorry to hear about what your sweet little guy went through. Seeing our pups deal with an upset stomach or intestinal inflammation is completely heartbreaking, and we are so glad to hear that he bounced right back once you switched him back to his previous routine. You are absolutely right—just like humans, every single dog has a completely unique digestive system, and even with a perfect, slow transition, certain clean, fresh ingredients just don't sit well with every individual pup. Thank you so much for giving our recipes a try and for taking such incredibly diligent, loving care of him during the transition. We are sending him the absolute biggest hugs and wishing him continued good health!
