This is very expensive. That being said it worked for our Bullmastiff’s diarrhea when nothing else did. It’s an amazing product.

Our mixed breed lab/shepherd has never had a long run of consistent good stools. Good stools were rare, softer stools the norm, and often significant bouts of diarrhea for weeks. We've tried all sorts of different foods (including the high quality sensitive stomach brands) and mostly resigned ourselves to the fact that we will need to keep Propectalin and Metronidazole available every few weeks. However, now we've been on this Hills Biome food for about 2.5 months now and what a difference it has made. We switched on a whim as a suggestion by our vet who had others pets of her own having issues, and knew what we were goin through. I was hesitant since we were battling 3-4 weeks of pretty significant diarrhea without getting better. But I did a hail-Mary and switched our pups food entirely on day 1. Literally the next day he had a firm and normal stool. I was shocked and my stress level came WAY down. We are now going on many weeks without any issues and completely normal stools and our pup even likes the food a lot. I'm not one to strongly recommend foods to others since I know that every pup is different and some things work better than others for different dogs. I can only say that I'm thankful that at least for now the Hills Biome has worked a miracle for us. My biggest hope is that having our dog on this food long-term is ok for his long term health. I also hope that one day the food will not require a subscription since not all pet stores carry prescription diets.

Our dog had fine poops for the first year of life. Then the allergies set in. He had soft poops for six months before we finally tried this food (after several other prescription / gut health foods) and within a day we finally had firm poops again. It has been a life changer for our pup. You do need to ensure your dog gets plenty of water as this is a high fiber food--we add water directly to the kibble. My only complaint is there are no other protein choices other than chicken. A beef and fish option would also be really nice.

German shepherd had chronic diarrhea about 6-7 weeks after transitioning to a high quality adult food. We tried a bland chicken and rice diet to no avail(stool would firm up but get worse again as soon as a bit of kibble was added). Vet tried pro pectalin and that did nothing. Vet introduced this food. Stool firmed up within 2 days and our dog loves it (he did not like other kibble much) . We are keeping him on it as long as things continue to go well.

This item works great on my dog and he loves eating it. Another great feature for the 8# bag is the velcro close after you open the bag. It's great to be able and close the bag o e handed. 👌

I like the good but have concerns about ground pecan shells as an ingredient. I see that Hills is now adding ground pecan shells in other varieties too. Hills is the only brand I have identified that includes ground pecan shells and I have seen some information, including from the AKC, stating that ground pecan shells are not safe. Why is this ingredient in the food? Can you reassure me it is safe long term?

PETCO IS NOT SET UP TO ACCEPT VET RX!! I contacted my vet after order was placed and I received a email from petco stating that my order would be cancelled. Contacted vet and they approved the Rx with petco but their system or AI never acknowledged their approval. I contacted customer care and also the chat. No resolution, order cancelled. What a waste of time.

Very useful for dogs with a sensitive stomach! I highly recommend it!
