| Oh dear, I don't want to create more controversy, but I think that Parti-Yorkies got their piebald gene in the same way that Biewers did--by crossing in from another breed. BUT, I have read absolutely nothing about DNA breed testing of Parti Yorkies, so I don't have as much data to go on as I do for Biewers--the evidence is much more clear in Biewers. It would be great to sequence the MITF (piebald) gene in Parti Yorkies too, just to try to get an idea of what is going on. I am willing to keep an open mind. We simply need more data. |

| The DNA study done by AKC tested males and females were not DNA'd. The dogs used in the MARS testing focus group were mostly dogs with direct German ancestry and many of the dogs registered to other Biewer clubs are siblings to these dogs. The BTCA has had many people come to them from other US registries and ask if they can MARS test their dogs and go from the current registry to BTRA. Some have tested as Biewer Terriers and were allowed entry while others tested as Yorke/Biewer crosses and Yorkie/maltese. Some in fact came back as Yorkie/Shih-tzu mixes. The other US clubs have not tested their dogs therefore have not been able to remove these mixes from their breeding programs thus leading to these results. |

Ahhh, you're in the THICK of it all right!! Someone also mentioned potential mix with s**tzu or Maltese. I don't remember which one that Mr. Biewer also bred - it was one of those 2. Someone else also mentioned a re-do of the testing since the 100 samples originally submitted by G.Pruett & company may be tainted. That would be the right thing to do. Certainly there are enough Biewers to test. Perhaps people are too afraid to do that now. Maybe breeders don't want to know the complete & messy history as it relates to their lines. In any event, it's my opinion that there's been sufficient breedings of the Biewer for it to be considered a distinct breed. IMHO, there's no reason to breed back to the Yorkie. It doesn't bother me in the least that some other breed was mixed in early on to create the Biewer. Don't all dogs descend from wolves anyway? At some point, all breeds were mixed with something else - save the dogs that were created in the Book of Genesis (I guess they just popped up out of nowhere after there was light & earth.)

You have a good point about German Yorkies, but my understanding is that pedigree records for them is not as good as in the United States. And again, there was no DNA testing back in the days of Mr. Biewer. About Biewer to Yorkie breeding, once that is stopped, and you start breeding Biewer to Biewer, the gene pool becomes fixed and the breed stops becoming more and more Yorkie-like. That would explain the MARS results showing that the Biewers they tested were in a unique and uniform group. About the Biewers that were tested by MARS, yes those mostly came from one club. I don't know whether the person who submitted the DNA samples claimed to be a vet or not, but it doesn't matter, because DNA doesn't lie. If someone has serious issues about the validity of the samples, they should ask for them to be retaken and retested, but I'm sure the results would be the same. I agree that it would be great to test all Biewers from all clubs, but since that might include Biewers coming from Biewer by Yorkie crosses, that would basically be like throwing mixed breed dogs into a purebred test--the results would be interesting, but they wouldn't be informative or normative. I understand that there is some kind of turf war going on with respect to which clubs have the "true and authentic Biewers." I would recommend that all of the clubs doing Biewer by Biewer matings get together, submit their dogs' DNA for analysis, go over the results together, and try to reach some kind of consensus. | |

| Oh, I forgot to mention that if you are getting a lot of different colored "Yorkies" (and I use the term loosely) from ONE litter, that is clearly a sign that breed standards for the Yorkshire Terrier are being ignored and flaunted, and people have been crossing Dog knows who to Dog knows what. Each color is not a separate breed--it's a sign of breeders gone wild. |

Here is the history of the Parti DNA testing as taken from Deb Mullins site: snowblueyorkies.com The Tri- color had been showing up in litters from Ashley since 1984 and Nikkos Kennel had been quietly placing them in pet homes and asking people not to say where they got them. Crownridge and Summit had obtained Parti colored puppies from Nikkos kennels and wanted them AKC registered with their true parti-colors . So in 1999 they convinced Nikkos Kennel to go to AKC and get them registered as yorkshire terriers parti color. This turned out to be a very lengthy and costly process to Mrs. Lipman,(Nikko's Kennels) as AKC shut down her kennel in 1999 for 18 months to conduct DNA studies of 42 litters sires and dams. She was not allowed to breed or sell or conduct any business during this time. 3 of the dogs tested were owned by Mrs Bogren(Crownridge) and 1 owned by Mrs Gesmundo(Summit Yorkies) During this study AKC also spoke to several other breeders about tri colored pups born in other bloodlines. Many highly respected breeders admitted they occasionally had these tri colored pups born. AKC went back as far as they could with the living dogs. They DNA'd about 42 litters. They also talked to a lot of the "old" breeders and they told them they had always been in the lines but were disposed of. In June of 2000. The DNA studies of Nikko’s Kennel was completed to the satisfaction of AKC. AKC deciding that after a study of the Yorkshire History and the DNA of the dogs involved in the study they were satisfied that the color can be produced in otherwise normal litters of Yorkshire Terriers. Hope that helps you.. Diana

Let's just say that without the RAW DNA results, AKC's findings MAY be suspect - even just a little bit?? Or are we all going on blind faith here? | |

| I found the article interesting as well and very easy to understand. It seems to me that the Biewer standard still has significant coloring on the back & head, which would suggest the mix with one other breed. I wonder whether it could be determined which one is the culprit? I know that Mr. Biewer had other breed dogs. Could DNA determine which breed supplied pie-bald gene? I have seen all white & other lighter colored partis - which I guess would mean a mix with more than one breed. There are really good & ethical breeders out there. There are also the GREEDERS, however, who breed everything under the sun. I can see very easily how other breeds could be mixed in - even on purpose - to obtain a desired look. Thanks again. Keep the information coming! Tracey |
