I am just wondering since you have so many friends in the Breeder forum why you would come into the General forum to ask this question? Maybe you should be asking all of your breeder friends how they feel about you having a litter of Yorkie mixes. I would very be interested to see what the response from them would be to your original post.
If you are looking for a puppy here is someone that already has a litter that was a great big ooops. Maybe she can give you one and you will not have to bother to breed yours.
