that's kinda a tough one, I'd try and break it imidiatly though, shaking isn't good, throw something that's not so comfortable to shake, a stick wraped with tie wire with some stray ends poking out, then with rope tie something that will dagle off the ends, something heavy and hard, so when she shakes it, it will hurt, it might be a little early to force fetch her, but she needs to learn not to shake stuff, I've seen dogs growl when they get close to bringing it back, but shaking is never good.
