Can anyone give me some good links as to why Purina dog foods are not good quality. Someone is posting on another board I am on that the beneful and Purina ONE and Pro-Plan as good lines of dog food. I am pretty sure this is not the case, but I would like the information to back this up when I go to reply. I did tell the OP about the dogfoodproject website, but this is someone who has replied to the OP's post saying Purina is a good food, but she used to work for Purina. Thanks!
