I am so glad there is hope now. These little babies give us such love and joy. I imagine you have had to spend money on other things you didn't enjoy as much as this baby. If it is meant to be, you will find a way. She is so tiny that even if her leg doesn't mend 100%, she will get around fine; and as we all know, they loved to be carried. I agree with you on breeders trying to breed these tiny yorkies on purpose. It really is just another way to charge high prices for a puppy without caring about the health and life of the pups.
There is something so wonderful about a yorkie, and I have had dogs all my life. Your baby is very lucky to have been found by you. You are in my prayers.
