Our new puppy is far more interested in our greyhounds Iams Lamb and Rice formula then the puppy food. He is on Pedigree puppy for the simple reason that we cannot get any other kind of food around here. I would prefer something better quality but am still searching for the answer. He has not had any digestive upset since coming home. I expected some loose stool from the new home and such but he seems to have the cast iron stomach. Just wondering if I should be concerned about the consumption of adult. I do feel better about the Iams then Pedigree for sure, but it is not puppy food...
