Thanks for worrying!! Actually, this week he has been eating all of his food--I moved it into another room, not in the same room where the other 2 eat, and he gobbles it up now--he's silly
Abbey and Riley both eat in their crates, so he doesn't have to "worry" about them getting near his food.
Thanks for all of the tips, I usually do pick it up after 15 minutes or so, because the other 2 are done, and ready to go out!!
