Oh yay! Congratulations! ^^
This is true about keeping them inside before they're fully vaccinated -- hope you bought lots of pee pads!
I know when I brought Nilla home I let her play outside for a few minutes, and then it dawned on me that it wasn't such a good idea to do that anymore, so she stayed inside for the rest of the time. It's a bit hard because it feels like a long time to keep them in, but it's better than having them contract Parvo or something else! You'll get to strut her around soon enough! If you need anything -- help or advise -- there are many people here who can help and are very experienced in all things Yorkie!
<3 Can't wait to see pics!
