Bhikku...the Biewer is different from the Parti. The Biewer is from Germany, they are German and U.S. registered although not AKc recognized. There is a standard set forth by the German club and that is the same standard we follow in the U.S. The Biewer keeps it's long tail where the Parti tail is docked like a Yorkie and the Biewer has a standard for color placement where the Parti doesn't. I have always been a Yorkie person through and through but when I met the Biewer I was hooked! I still love Yorkies but the laid back personality of the Biewer pulled me in...they are quiet yet playful, loving and loyal...not to mention simply beautiful with their striking colors and plume like tail. I have 4 Biewers and I don't think you would be disappointed if you decide to add one to your family.
As for the Biewer not being from the Yorkie...well...I won't even get into that controversy.
