Hi and welcome to YT!!! Have you checked out the line by The Honest Kitchen? They have fabulous freeze-dried raw food that you simply rehydrate when ready to feed. There are currently 3 different formulas (two without grains) and another on the way that is vegetarian. The protein levels of this raw diet is much more in line with regular dog food. All the ingredients are organic, human grade and the plant is FDA approved.
I don't feel the cost is that much and the convenience is great!! They will send you a free sample if you check out their website.
