Maggie does this is well, but her bowls are in the family room where we are when she eats, and where her crate is. Her crate is next to the fireplace, and the bowls are on the hearth (very low and stone, so easy for clean up!) - Maggie likes to take mouthfuls back into her crate. Sometimes mid day I hear crunching and I say, "did you save some of your breakfast?!" lol. I really don't think this is something you can train then NOT to do, I think you just have to sort of adjust

I know with Maggie, she's just so darn happy to be eating, I think she can't stay still long enough to eat from the bowl
