I don't what is wrong with this food but it gave both my pups loose stool. I have been picking up pudding poops for the last 3 weeks thinking it had to do with the medication they were on for intestinal parasites. But once they finished the meds, it did not get any better. It wasn't until I took a risk changing their food to Purina Pro Plan Puppy (for under one year) that things took a turn for the better. Even the first couple days of introducing the new food with the 25% ratio made a difference. Now that they are at 75% Purina, both pups' stools are completely solid and easy to pick up. No more pudding poops.

Sierra doesn’t really care for it. Her vet recommended this brand to help with allergies. So far it hasn’t helped the itching and It’s very hard and extra crunchy. She’s a large breed but still a puppy. Switching back to the smaller one when she finishes this bag.

Our picky Border Collie refused to eat this. It was painful trying to get through a bag. Ended up going raw when he turned 1. We tried many brands of dry and canned as well as toppers. Nothing worked.

These are my Doodles favorite toys! But the bacon scent created an issue as it smells like food. Both my dogs react to the bacon and want to argue about it. I took their favorite toys away because I didn't want either of them getting hurt. Please make an unscented option. Thank you

2 or 3 dogs did well but made one vomit.

I have 3 dogs. 2 of them do well on this food however the 1 can't tolerate it. It makes him vomit. So I will not purchase again.

I got this because it’s what the breeder was feeding them, she mentioned that some things had changed with the recipe and I agree that it seems a bit greasy. She warned me that he may have an allergy to the food as it’s common with dogs and chicken. So far, he seems fine but I’ll eventually wean him off to a different brand or possibly start making dog food at home again.

Eh

I'm sure the food itself was good but the bag was ripped and most the food was inside the box it was delivered in.
