Yes, purina is supposedly a bad food, but, not all purina foods are bad. For one thing, the food we had to have our golden retriever on, was made by purina, it was only sold through the vets, and the pro plan is also one of their better ones. When our chihuahua was growing up over 40 years ago, purina was one of the only foods out there on the market, he was on purina dog food all his life, and lived to be 19, never had any health problems. As I've said before, no matter what kind of food anyone feeds, as long as the dog does well with it, no allergies, etc then keep them on it..I truely believe in this, I have seen many dogs sicker on supposed "good food", than some of the "bad food"..
