Just want to welcome you to YT. Yorkies of all sizes have been known to "bite off more than they can chew," so to speak. They think they are bigger than what they are. In one of my Yorkie books it says how needs to be careful because many Yorkies have met their demise attacking a larger dog. My tiniest two senior girls are very strange dog aggressive. I know that there are training techniques. Wouldn't hurt to do a search on "dog aggression."
