my poodle does a nose nudge thing. If he's being left out of something, like a couch snuggle, or something, he sticks his nose under our arms and shoves his head under there. when he was a puppy, he would also do the land shark thing. Zoom around the back yard and bop you in the butt. Also, his favourite thing in the world is when someone is standing, and he nestles his head in between their legs and asks for a full body scrubby.
