In Germany the ones that look like Yorkies are registered as Yorkshire Terriers and the ones that look like Biewers are registered as Biewers. There are many great Biewers in the US that have a splitter parent. They are not considered splitters since they look like Biewers. A Biewer will produce only Biewer coloring when paired with another Biewer. When paired with a splitter 50% of the offspring should be Biewer and 50% splitter. When paired with a Yorkshire terrier that does not carry the piebald gene 100% will be splitters.

The Mars tests did come out as 100% Yorkie though for the 2 splitters that I have, but I just don't know how a dog that comes from a Biewer which does not test purebred Yorkie and a Yorkie could be 100% purebred Yorkie. To me it would make more sense to register the splitters as Biewers, but with a color fault.

I would compare them to horses. In the Paint horse world, if a horse is born without enough white, they are classified as breeding stock. They are still Paint horses, just not able to be shown. They make great companions or if confirmation is right, breeding animals.

With Appaloosa horses, the offspring without at least 2 characteristics have to be DNA tested and then identified with either a tattoo or whorls (like cowlicks) They call it CPO or Certified Pedigree Option. The animals that have gone through the CPO requirements are allowed to show with the colored Appaloosas. They are still Appaloosas even without the correct color pattern.

Here is a picture of our two Appaloosas without characteristics. They are both geldings (altered males) so there will be no offspring.

nice horses
