If the paper says your dog is a yorkie, it's a yorkie, especially if you got it from a reliable registry, such as the AKC, and even then the registry is no better than the breeder. Breeds are manmade things, and the word silky or yorkie has a certain meaning but not every purebred dog is a great example of the breed. Many people breed whatever dogs they have, and without selective breeding for certain qualities a purebred will look like a mutt in a few generations, but it is still a "purebred." There are genetics tests that can tell if your dog is mostly yorkie, but they are not 100% accurate. I'm more concerned with people breeding for the wrong reasons. We have too many pets available now, and the only breeding that should be done is to preserve, protect, and improve the breed. Unless your dog is a wonderful example of the breed, you shouldn't be breeding. People seem to think every "masculine" looking yorkie is a silky, but Silky's aren't really that common in the States, they are more prevalent in Australia. So just because a yorkie has a longer nose, or doesn't grow coat very well, it does not make them a Silky. Bottom line, is if your dog isn't a great example of the breed, you shouldn't breed, no matter what the registry says of it's bloodline.
