Isn't this all amazing? I never cease to marvel whenever Stump does this. He pats my chin with his paw (kind of a double-click ) and he seems to do this especially when I'm feeling sad -- somehow he just figures it out. Emmett raises his right paw when he wants to be petted or when he wants to give a headbutt; it's really cute. Emmett also will touch noses which is really endearing; I just say "touch nose" and he'll usually do it. Stump, however, will not.
