I use Tast of the Wild. It runs pretty expensive, around 40 to 50 bucks for a 30 pound sack, but I can feed my 65 lb dog on only 4 cups a day. He has been on it since a puppy and performs great on it. My mom and brother are feeding their dogs the same food, ones a few months away from 2 and the other is almost 3 months old. You can get it at Tractor Supply Company, or more than likely any of your local feed stores. I actually found it ten bucks cheaper at the local feed store.
