I would question the ratings the link for Dog Food Analysis gave. It neither gives the author's name nor any contact information nor his work. It doesn't give any information on why the author isconsidered anexpert in the field. The only information given is his contact with Boxer World. I've known people who done alot of research but that does not neccessarily make them an expert. So, I would take it with a grain of salt.

I feed Pro Plan. It may not be the best but its considered good. My vet says, "it's a well balanced food." If its good enough for my vet, its good enough for me. BTW, my dog stools are nice dark and hard and relieves herself once a day.
