It's just that all of the "high grade dog food" vendors call bloody-murder over the fact that we're feeding our dogs industrial chemicals and that doing so just couldn't possibly be healthy for the dogs.
I'm actually curious to try out "dog food for humans" and if I feel as good or better... I'm stopping the extra time, money and work involved in making my own dog food and feeding her kibble with the occasional piece of meat now and then.
