Yeah, shaking here too. Wesley learned it at like 5 weeks old when the breeder's son taught it to him-totally ingrained. Speak is another one, but he's just barky. Luckily, he wasn't super reinforced so it's not a default. His current default behaviors are backing up, sad puppy (chin on the floor, your lap, the couch, whatever) and of course shake.
I will definitely not be teaching my puppy to shake after being hit so many times with those claws. Maybe she can learn how to when she's, oh, eight years old.
