Your little one is precious and you've been blessed with a healthy Yorkie too.
Great info has been given above towards the tiny ones. As said, many times things said are negative as some breeders find they can advertise their tiny ones as "rare" so obtain more money.
Other's might not see the special extra care in caring for a tiny - only seeing a cute purse baby, etc. Not realizing what all is involved.
I myself will be obtaining a tiny soon, I think they are adorable. However I feel I am educated enough to give the care etc that they at times need and I too am willing to pay probably a higher price. (sometimes one must pay a higher cost for getting exactly what they want, goes for all things)
I also have Schatzie, she is my biggy Yorkie (8 pounds)
So happy to hear you love your tiny fur baby as you do, she's a blessed fur baby to be under your wing.
So I love all Yorkies, tiny or big!!!!
