In the end you have to live with whatever you decide to do when it comes to breeding your male.. Always remember there is NO perfect yorkshire terrier, alot of people would like to think they have one, but NO one does! When I first started into breeding my male was far from perfect! But he did not have any genetic health issues and did come from descent lines.. Do I still have him no, he is neutered and in a wonderful pet home.. I feel my program has come along way in the last two years, but everytime someone breeds (rather for show or for strictly pet puppies) you want to better what you have with each and every breeding..
I also agree that he has an adorable face.. One you just want to give a BIG kiss to!
I wish you luck in your decision..
