Lol. Gracie does that too. She does it if I ask her if she wants to go outside, she does when company comes over, she does it if she wants to play, or if she wants food. It's even funnier when you do it back to them and they look at you like your nuts. When we got Gracie they told us that it's a doberman thing, but I haven't ever seen any other dobes do it. I love it though. It cracks me up every time.
