Purina One is pretty much all my dogs get along with their homemade food, although they sometimes get Canidae. I found out that most of the specialized pet store foods like Iams actually test their products on dogs. I'm not against testing dog food on dogs to see what they eat, but these dogs live in cages and are taken out to eat and thats it for the day. I won't feed that food to my dogs. I guess its up to the consumer and the dog. Most claims about which food is better are false anyway.
