Yes they are purebred and can be registered with AKC but cannot be shown because of the rules. I have even known people who had one parti in a litter
where both parents were show dogs and were carriers for the parti gene.
One of my partis came from parents with championships in their background and the owners would have a fit if anyone discovered that this dog came from their lines. I think it is hilarious. The only difference in her and her parents are the color. Years ago, these dogs would have been culled (look up the definition if you dont know what culled means). It is appalling that people did that so that they could keep their dogs to a color that was considered correct. Same thing goes with the goldens. I actually had two golden carriers produce three little golden girls and had no idea either of them were carriers for anything. People sometimes forget where these little dogs came from and what their ancestors looked like. Also people forget that the breed group who made the rules and guidelines as to what a yorkie SHOULD look like, are only people and have their opinion. I am glad that the partis and goldens are allowed to be registered. I have never shown nor do I care to. Someone on a group last week was reporting about a dog that was killed at a show by another dog with aggression issues. Those are the dogs who should be eliminated from showing. As you can tell I am a big advocate of the partis and goldens. Good luck with your little girl. If anyone tells you she is a "throwback" my answer is "yes she does have some of the original genes of her yorkies ancestors". I am attaching two pictures of my latest litter of partis. Enjoy that little girl. Sounds like you were extremely lucky.
