The best food is one the dog does well on, likes to eat, and you can afford to feed.
I feed plain kibble in the morning, and kibble with just a bit of canned in the evening. I've fed a lot of brands over the years, and keep coming back to Pro Plan. My GSD and APBT are both currently eating the Sensitive Skin and Stomach Salmon and Rice formula kibble, and whatever canned food I happen to get on that trip to the store.
