I don't understand what you mean by bred down but I am assuming you do not mean their size. There have been parti/tri-color Yorkies born since the breed was introduced. When 2 dogs are bred that carry the piebald gene as a recessive, there is a good chance a piebald Yorkie can be born..As with every breed there were several different breeds used to develop the dog that we now know as YORKIE. If the background of the Yorkie is studied, one can very easily see how these colors can occur. Remi's parents are both standard colored. He is the adult in my avatar....
I love my standard colors but I also love my Biewers and my AKC reg parti male.. If these dogs had defects consistently, I certainly would NOT breed them as I would not breed standard colors with health problems....
The Biewers who worked to get these colors in healthy dogs named them and that is the reason they are called Biewer..otherwise they might have been called something else... |
