Sorry, I'm no help. Both of my dogs would eat as much as I gave them at any time of the day. LOL You'd think I was starving them.

Is it a problem to leave the food down? I know some people do not agree with that, and that's fine. But my brothers dog never ate all of his food right away. So they'd just leave it and he'd go snack on it throughout the day. Amazingly all the other dogs (their one and my two) learned that they didn't touch Boo's food. That might not be so easy for most people.

But your idea of giving him the big meal in the morning sounds like the perfect solution!
