<<The point previously made about the parti's not showing up in show lines is what really got my attention. If it really has been there all along, recessive or not, then it would have shown up a lot more often along the way -- not just cropped up in profusion after the Biewer news. The piebald markings would be showing up in professional show breeders pups, and not just the obscure lines that wind up tracing back to someone with multiple breeds. >>
Exactly. I have only been in this 10 years. I have had puppies with white blaze as you mentioned. That white blaze does blend in with the tan or gold in the mature dog that had this at birth. You do not see any white patches on the mature Yorkie.
The original claim, as I recall, the development of the Biewers, was that the breeder took those Yorkies that had the larger white blazes and bred them producing more and more white to eventually get the large white patches. I think this is nonsense as no show breeder has ever had this yet.
And we have bred dogs that as puppies had white blazes on the chests. It is not unusual.
Don't forget that some of these breeders that are producing parti colours have multiple breeds OR some are not AKC registered as such many have alternate registries such as Continental Kennel Club who has accepted registrations based on a photograph alone. What the heck is that? I have seen Yorkie/Maltese crosses that you would be hard pressed to know that isn't a Yorkie. Breed it however, and you will know what was in its background and that isn't purebred Yorkie.
Also, those AKC registered, you also have to be very cautious. Any breeder can submit the paperwork for a litter to be registered from certain AKC registered Yorkies. The truth of the paperwork lies entirely on the shoulders of the breeder. It is always accepted as truthful, until something happens or is questioned that proves it otherwise.
And that sort of thing can come from very far back and be very hard pressed to prove.
Even DNA'ing, it will show that that is the mother and father of a litter, but it would be hard pressed to go further back much into generations especially if those dogs that are grandparents or back further are no longer alive.
That cross breeding could have been brought in 15 20 years ago and once the particolour is produced, you can keep that line going but DNA'ing is not going to find the culprit way back in the pedigree where the indescretion accidental or otherwise occured. |
