Rachel,
You may want to
check out this link. Admin chose to make it a sticky because of the quality of the information it contains. I believe you will find many here believe these are good guidelines for choosing a yorkie. I don't say that excuses rudeness, but it may give you some background information on the thoughts of others about what a puppy mill is. Honestly, when I look at that site I see red flags. Red flags I've only learned about after I brought Ginger home from a place run by a really nice older gentleman. Ugh, what a mill that turned out to be.
I understand that you are emotionally attached to this girl and that you have made up your mind. Honestly, I'm not judging you and I do wish you luck. I just want to help you see why your breeder is being judged so harshly.
Hope this helps.
P.S. Yes your blingee is adorable.
