I agree with Kalina about the blue born. I did read that you (OP) said you had read on here that some breed blue born dogs to strengthen the blue in their line. I think you may be mistaken. Some breed the red-legged yorkies to bring stronger color back in their line, but I have NEVER read anyone recommending breeding blue born to strengthen the blue. For one thing, it is not the same thing at all. Kalina has already explained a little about the blue born genetics and linked more info for you. I would read that and make sure you understand that a blue born should never be bred. Here is another reference to read on them:

Almost every yorkie owner has had family and friends say they want a puppy from them. Let's face it -- Yorkies are adorable! Some of these people are even serious and not just saying what they wish or think is cute to say. But -- breeding a toy dog is serious business. It should not be entered into lightly or assumed that it is such a natural thing they will take care of it on their own. Since you say you do not want to be a breeder, then you should not breed, as you would then be a breeder, just not a very good one. To be a good breeder, you need to spend some time researching, reading, talking, absorbing, and studying the breed, mating, whelping, care and rearing of a litter, etc. You need to have your male and female tested for genetic conditions and diseases that can be passed on either to each other or their offspring. You need to have them evaluated by experienced breeders who are very knowledgeable and can compare them to the standards they should meet before reproducing. Just to have cute puppies, is not a reason to breed. There are plenty of cute puppies in the shelters and rescue organizations. Leave breeding to the ones who are willing to invest the time and energy to do it right.
Love your pups, spay/neuter them and relax. Those friends and relatives will live without one of your dog's pups. If they really wanted a yorkie that much, I figure they would probably go ahead and buy one of their own, regardless of you being able to hand them a free one. With all of the other stressors you have mentioned, this does not seem like a good time in your life to have puppies anyway and you certainly do not have an appropriate pair to mate.
Since you are not bonding with this female, I would take Manolos up on her offer to buy her now before either of you go through any more frustration. I do not think you are abusing her. I do think you are unhappy with her and I am sure she can sense that at some level. Better for her to go now to a new home and hopefully bond with a family that is right for her. I do think there are dogs that are not right for every family.
I have previously tried to talk people into being patient and working through problems with their new dogs. After more than one tragic result, I have changed my mind. If someone is unhappy enough to come on a Yorkie forum and say they are going to rehome their dog, then I think they should do it for the sake of the dog. So, I will not encourage you to work with her or seek training remedies. Since you have already voiced the desire to sell her as soon as you can get a litter from her, I would encourage you to forgo the breeding and rehome her now. Best for all concerned, imo. I have tried to make sure I have worded everything in such a way that you will really consider it and not react in the sarcastic, obviously irate way you originally responded. I don't want to make you mad, but do want you to take onboard the information and opinions I am relaying. Wish the best for all of you!
