I would call the vet on the throwing up, they may want a sample, as far as being calm, give her a few days. When I brought Roxy home she did the same thing. The most quiet, sweet lil girl. It took her about 2 days and then she started exploring everything from my shoes to electric cords. So, baby proof your home! I personally think going from the enviornment of mama and sib's to another compleatly different one with different smells, sounds, etc., is just hard for them. I'm sure she will adjust fine. Let me know how she is in a few days !
I have never met a quiet Yorkie ! Roxy still naps on and off all day. They are babies...lol.....and everyone here is wonderful and very helpful.
