Iams
2
My dog used to eat IAMS food, but then one day just quit eating it altogether for no explainable reason. I was not aware that they changed the formula, so that might have had something to do with it, but I guess it says something that my dog (who will eat almost anything else he can get ahold of) would rather go hungry. I switched his food (and have actually never found another food he won't eat) and he's been fine ever since.
