Glad to hear you have your yorkie back with you. I IMO would probably leave it alone and thank your lucky stars for how it turned out... But... I would rather call my Vet and make immediate arrangements to get your Yorkie Micro chipped to settle your nerves! Again I say in my own opinion... I know I would feel a little better knowing this in done.. just in case it ever happens again. Glad it is all right now!
