Simply put...the Biewer originated in Germany (not the UK) in the mid 80's. Over the years it was selectively bred, named after the founder, and a standard was set. The standard is similar to the YT, but calls for specific color placement (white paws, tip of the tail, symetrical coloring on the head and face, etc) and calls for a tail. It has been recognized as a separate breed by some organization and can be shown in some venues. (not AKC)
Partis are tri-colored Yorkies. They can be registered with AKC, but not shown in AKC, but can be in some other venues. There is no standard set for them that allows for the non-standard coloring, but typically, most Parti breeders follow the YT standard with that as the exception. |
