I'm not convinced that corn is a complete protein.
I don't know how much different canine digestion is from humans, but for humans, I believe that corn and beans together make up a complete protein, but corn is not a complete protein in itself.
Maybe there's a bean product in Hill's that combines with corn to make up a complete protein, but if that were the case I think the letter would have said so.
Of course, I could be totally wrong. |
