I am sorry you are having this trouble. Yorkie bites can be very serious. I was bitten trying to break up a dog fight between two Yorkies...... down to the bone in my hand. I am very lucky that I didn't require stitches or that it did not get infected 'cause I wasn't about to go to the hospital. In my city, maybe even in my state (??) doctors and hospital staff are required by law to report ALL dog bites to the authorities. There was no way that I would allow one of my babies to get a rap sheet and risk losing them so I suffered......
I would strongly suggest that you find a professional trainer who can give you some good hands on advice/training before you have a more serious incident. If it ever comes to the authorities getting involved, you might not have a choice in the matter. Sending hugs and well wishes to you, your family and your beloved furkid.
