My dog Lucy has a habbit of karate chopping everything. It is kind of embarrassing when you go to the park and she chops other dogs - lol. I've even had dog owner ask questions about it. She doesn't mean any harm, she's just cute. Plus, she is only 10 pounds!
She also lays on the floor when she's really excited and happy and swims. She literally lays her tummy on the floor and does the breast stroke. She's the best, makes me laugh all the time.
Oh, she also likes to steal underwear out of the hamper when we have guests. She'll run right in front of everyone with them dangling out of her mouth. Even at dinner. Thats always nice - lol.
