Ddog has a good understanding of “go to bed” and “stay” but at meal times he stalks the children for any titbits they may drop out of their uncoordinated mouths!
It’s not much of an issue but I’m trying to prepare him for boarding (other thread) and I need to instill some manners in to him 
I’ve started to send him to his bed when the plates come out; he gets a high value treat when all four paws are in bed.
I then use “stay” and go back to him at increasing intervals to reward him with the high value treat. Once the meal is finished, I tell him “all done” and don’t treat him so he comes out of his bed.
Does this sound right ? When should I expect results?
The goal is for him to go independently to his bed when the plates come out ready for meal times (with a prompt). Is this realistic?
