The question is can purebred yorkies have the white patches on the head, sides, legs, etc. without the introduction of a breed with that color pattern such as a papillon or shih tzu. Remember, Mr. Biewer also bred shih tzu. It's the white patches on places other than the chest, feet and a small dot on the chin that leads most to believe that the origin of the parti is the result of a cross breeding. |
Do you have a source for this? Just curious.
It should be noted that the first generation breeding between a yorkshire terrier and a shih tzu would NOT produce a tri colored puppy unless the yorkie also carried the piebald gene. Not to mention shih tzus have an undercoat...biewers do not.
With research telling us the "foundation dogs" that have produced tri colored puppies, whether biewer or partis, originated from kennels in the UK...I would say any mixed breeding, if it occurred, took place there.
