Yorkshire Terrier Biewer, also known as à la Pom Pon, is one of the varieties of the Yorkshire Terrier. Melanocytes dysfunction, observed for the first time in 1984 by German breeders Gertrud and Werner Biewer, is responsible for white patches on the dogs’ fur. Thanks to the appropriate selection of genes, a random mutation gave rise to a variety characterized by a three-colored, white-steel-gold coat. Like other terriers, Biewer's hair also requires clipping, combing and tying, so that it does not cover the eyes and ears or hamper movements.
