"She continues to have several health problems that will stay with her for her entire life because of her small size and because she was purposely bred to be tiny. While I love her, I am very lucky that I can afford to properly care for her because I have had to pay thousands (not kidding) at emergency vets and have talked to other owners of tiny yorkies who have had similar experiences."
