I have a morkie named Bella, a Brussels Griffon/Poodle/Yorkie/Cairn Terrier (didn't know he had Yorkie until we had him tested though), and a new little purebred Yorkie on the way.
I was welcomed with open arms (by most) regardless of the fact that I did not have a purebred Yorkie.
Welcome to YT!! Most of us are all about the pets and helping each other out.
It isn't so much about their bloodlines as it is about their lovelines. 
Again, welcome
