HI! I don't know if you found your chorkie or not but the breeder where i got my Kissy and Angel had an OOPS breeding (chi/yorkie)and she is selling her pups on her website. This is a GREAT breeder and many of my freinds have also received yorkie puppies from her. The website is
www.trenastoys.com. click under yorkies and you will see the OOPS listing. It is funny to read about it. The puppies are ready to go and there is 1 F and 1 M left. If you are still looking for one, i would recommend this breeder
...she is NOT a puppy mill and is very proud to show anyone around her place. She treats all her dogs as her babies. She lives outside of the D/FW area in Texas.
Good luck finding your new baby!!
