Remember when you were little and there was always that one kid that would lick one side of the cookies to make sure that no one else ate them?
Well one of my dogs has a great new slant on that. He eats as much dinner as he can as quick as he can then pukes it up in his bed as if to say "This food is mine. You can have some if you want, but I don't think you do."
Then he smugly re-eats the hole thing, but this time slowly, so it can be enjoyed.
