There is no such thing as a "teacup yorkie" - that's just a marketing term. The correct term is just "yorkie" and the standard for a yorkie is to be 7 lbs or less....so you have a standard yorkie - he's just on the small side. There isn't anything you can do to affect/change his ultimate growth level - it's genetic. Are you worried bc of safety reasons?
