There are a few breeds out there that came about as a mismarked version of another breed. One I can think of off the top of my head is the "American White Shepherd"I'm confused.. Are those just Yorkies with white markings? The site you posted wasn't offering enough info, so I looked up the breed club website. Seems like they're just mismarked Yorkies...?
What in the world is that??? Looks like a Shih Tzu mix to me. The standard? How long has this "breed" been around? What standard is that from? The names on that pedigree read like a Rottweiler or German Shepherd. lol Very Very Strange.
