Mocha has a bunch of chew toys, but he doesn't really "chew" them. He usually just takes it in his mouth and shakes the heck out of it (by shaking his head side to side). He's not an aggressive dog, but he usually growls when he does this...it actually looks/sounds like he's trying to kill his toys

Does anybody else's Yorkie do this as well? Sometimes I worry 'cause he'll fling it around really fast and hard and I'm scared it might put strain his tiny little neck. Is this kind of behaviour with toys safe and normal, or should I try to discourage it as much as possible?
