At first I thought the "white yorkie" was just a website name to make his/her site different. Then I looked at everything everyone pointed out and now I've changed my opinion, that person is confused about what they are talking about. A biewer is a biewer, there is a standard as to what they're suppose to look like, where as a parti is a cute yorkie with a gene that makes it have a white coat and random markings.
Did I learn well from my yorkie friends or what!!
I think someone needs to go educate the author of the educational blog.
