i thought that this was an interesting topic. I want a girl next only because i have a boy and I want one of each. (not to breed all my pets will be altered) I would be just as interested in a young adult as I would a puppy. i love the smaller ones because i try not to leave my dogs home if I don't have to. It is alot harder sneaking a 12lb dog opposed to a 3lb, hehe I have tried. I think that the most important factor with my female will be temperment. Structure is also important to me, more than size. A well built yorkie looks beautiful regardless of coat, color, and size. thought that i would add my 2 cents
