If they are used to eating corn, then I'm sure they do appreciate it. If they're not, then you might be hurting more than you help.

Do you mean that "sudden change in feed" theory? What about when the grass greens up, the apples ripen and fall, and the acorns drop from the trees. They - and may other things in nature - are sudden changes in food sources...

Not a theory at all; didn't you ever change your dogs food suddenly and have them get sick? The grass doesn't suddenly green up all over, the apples or acorns don't all fall from the tree in one day. Although seasonal, these foods get incorporated into their diet over a period of time. I think you mean well, I just happen to think you're wrong.
