I would try Victor' Pro Plan Plus. It has a five star rating, and is 30% protein. The primary ingredient is beef meal. It has 30 % protein, and no corn, wheat or soy.
I buy buy it at a feed store here in Tx, and pay $38.00 for a 40 Lbs bag. They have a website, victorsdogfoods.com. They have a lot of feed stores they supply in Ky. On their website, check for locations near you. It is a great dog food.
