Ha.... haha. Ok, now I get it.
If you want to be believe dogs are designed to digest corn, and that they ACTUALLY gain anything from eating it, then you go right on ahead believing. I don't need a peer reviewed studdy to tell my dog is a CARNIVORE, with the digestive tract of a CARNIVORE, designed to process meat, not corn or grains.
Dogs have survived thousands of years WITHOUT processed corn meals and glutens in their diets. The very fact that the corn absolutely MUST be cooked in order for them to gain anything at all from it, is proof enough of that. I don't see many wild dogs cooking their food, but maybe I'm missing out on something here.
I'll stick to raw, thanks, minus the corn. I suggest anyone else feeding their dog, kibble or otherwise, do the same.
