I've been studying the best kind of dog food to feed Golden Retrievers and I'm coming up with "grain inclusive"...not grain free. The Morris Foundation in CA has been studying Goldens for years and I am impressed. Also UC Davis Vet school......I have been feeding my almost 2 yr. old female (spayed) Golden Purina Pro Plan Sport. Any ideas or comments out there? I've talked to my vet and it's a toss up between grain free and grain inclusive but it appears that there's much more conversation and awareness of this topic including my vet, and it appears that grain inclusive is the way to go.
