A breeder told me a long time ago to try the Kirkland dog food in the green bag. My Dane at the time had tummy issues and she said that the Kirkland green bag was made in the same facility as Diamond. I don’t know if that is true or not but I put my pup on the Kirkland and -poof- no more tummy issues. Now, this may not be true for every Dane so please talk to your Vet. I am not a Vet, nor do I play one on TV.
