I just want to add to the genetics of the biewers. To do this we need to start at the beginning with the founder Mr. Biewer , the history of the Yorkshires and what the word pie-bald means. So everyone put your thinking caps on. Let us start with the Yorkshires their coloring is a give me, you have your black backs and your silver backs, right? Okay now we will introduce the word pie-bald which means "marked with two different colors, esp. black and white, (commonly used in other animal breeding as well) this is where the white was introduced into the breed. Sad to say many breeders used to kill these puppies ( having white in their coloring) as they didn't want others to know of this color in their lines. Some will tell you this is a sign of mutt being in your bloodline somewhere. Now Mr. Biewer took the recessive pie-bald gene carriers that are Yorkies and mutated that gene to develop this breed. There was several breedings to achieve this and as he introduced other recessive pie-bald carriers to his program as not to continuing inbreed.(If you have had the opportunity to see his picture of his dogs on the runway, they weren't all Biewers in that picture.) That is how different bloodlines have developed. All of the Biewers start with the Master parents, as we all started with Adam and Eve. And here is another little formula for everyone, just because you breed two biewers that doesn't mean you can't still get a yorkie. I have seen this on the whelpen pages of German breeders web sites. So don't be disappointed if you get this, it can happen, as genetics go they can pull from their ancestral genes. I hope this helps clarifying the history of how the biewers came about, So if you ask me are the biewers different from the parti-colors, only is they were breed with another breed of dog such as the maltese, ect.(Which some breeders are doing this for knock offs,now) If the parti-colors comes from a recessive pie-bald gene mutation, then it would be the same dog just different lines, which that may differ the color pattern in some. Of course the parti color would have to have the same standards of the Biewers, no docked tail (which is part of the standard white to be at the end of the tail.) and that all four legs and bellies are to be white. As the biewers have the black and white backs, as some of the parti colors include some tan or brown in coloring. That may be where we seperate the Breed. |
