I do agree that the Biewer line and the parti line have went different ways since the beginning which does make them different, it makes them different in the same way that the Durrer line is Different than the Parquin line or any other line of breeding one chooses to accomplish. To me the fact remains when you trace both the Parti and the Biewer ,They came from 2 traditional yorkshire terriers, and both from Streamglen Shaun. IN my opinion that makes them a Yorkshire Terrier no matter what name you call them. To me the Biewer Terrier is a line of the yorkshire terrier |
