Okay.
Very interesting. It's a catch-22 though - can't be a seperate breed but 'can't' be a variation of the current breed....
I have wondered what the actual lineage is, since I have never seen one. But, this is all very interesting.
Would 'parti people' like to see it as a variety of the Yorkshire terrier? I can't see the possibility of a parti yorkie ever competing against a 'standard' yorkie.
