It's nice that you are seeking opinions/advice from YT members.... please remember that most people on these forums are just yorkie owners that may have a few years of experience with yorkies (myself included). Please do not take anything you read here as gospel. There are good and bad breeders all over... with home raised puppies and kennel raised puppies.
Wishing you the best with your new baby! Keep us posted and pictures please.... when you get her!!
