The parti yorkie has been breed and registered in Germany for 20 years. They are called Biewer Yorkshire Terrier a la Pom Pons. Some people in the United State (and Canada) have imported Biewers and are trying to stay true to the standards set forth by Werner and Gertrude Biewer. Much has been learned in the short 20 years of the tricolored yorkie's existence, but much has yet to be learned too. To be registered as a Biewer there are certain characteristics that must be met. White tip on tail (not docked), four white paws and legs, White belly, white on head (symetry is preferred), The back can have the darker color. The head should have three colors. The standard still says 7 pounds and under. The coat and build should be that of a yorkie, since they are after all full yorkies and nothing mixed in. The coat pattern does come from a recessive gene, called the piebald gene. Since it is recessive the puppy must get this gene from both parents. Two Biewers will always have Biewer pups. |
