Our yellow girl Gully does the same thing.
She has a large tartan dog bed that she loves to shake about sometimes.

She is a good dog most of the time but she knows its 'her' bed and she loves to harass it.

I can get her to back down if I am stern but the one thing that is guaranteed to work is to drop her blue indian rubber ball beside her. She then gallops after it. Mind you we now have a large clumsy lab dog chasing a ball around the house but I can get her to bring it to me because she wants to play.

Oh a treat would work too but I dont want to give her a treat for shaking things.

Running outside will bring her her galloping along too and I will do that if I want to chase her around outside
