So I have been feeding my dog, Peanut, Kasiks dog food, and the bag is almost empty. I really want to feed him the best dog food possible, so I asked my vet what a good dog food was and he suggested Purina Pro plan dog food. I am definitely not a vet myself so I wouldn't know for sure, but I have read tons and tons of articles about how Purina has killed dogs, made them sick, and just that overall it isn't a good dog food to feed your dog. Are these things true, or should I go with my vets recommendation? I am really confused because if he is wrong how could he get something that is all over the Internet wrong. Please help.
