I have a question. Is it being implied that it was intentionally added by the grain supply companies to make the grain seem "richer?" Or is it being implied that the dog food companies used grains they knew were "supplemented" to make the dog food appear to have more protein. I have heard it said in such a way I am not sure who is accusing who of what anymore. Of course whichever way, we would have to assume that the companies were unaware of the possible side effects. (?)
