It's odd that there is any mystery about a dog that had it's origin only 25 years ago. You would think there would be complete documentation of every step of its development, including photographic evidence. Any gaps in documenting or questions left unanswered brings the entire enterprise into question. At first glance, the story of the Biewer is quite remarkable, with the odds of what is said to have happened being much less than winning the lottery 2 weeks in a row. What kind of canine alchemy was going on there?
I found this info on the web. Not sure how credible it is, but it does offer some pedigree info. Here's the link.
WHAT MAKES IT A BIEWER YORKIE
Here's a bit from the link that I have a question about.
~~~~~~~~~~~~~~~~~
"
The ORIGINAL Biewer Club is the "ACH" - Allgemeiner Club der Hundefreunde Deutschland - ACH-L e. V. If GERMAN registration is a BIG DEAL to you then this is the registry that you should be registering with. If you register with any other German Registry then you are NOT registering with the ORIGINAL OFFICIAL German Registration Club and therefore should not be squawking about any United States Registry."
...and this
" History:
The Breed of Biewer Yorkshire Terrier A la Pom Pon was officially recognized in 1986 by the "ACH" - Allgemeiner Club der Hundefreunde Deutschland - ACH-L e. V. The Biewer Family is given the recognition of producing the first Biewer Yorkshire Terrier A la Pom Pon born on January 20, 1984 by the name of Schnnefloecken von Friedheck or better known as "Snowflake". The Biewer's lived in Hunsruck, Germany."

Now, I may be reading this wrong, but it seems like the Biewer was first recognized by its own breed club and registered with it. What's that all about?

Did Herr Biewer not only breed the Biewer, but started his own breed club and registry? If this is the case, all I can say is how 'convenient'.
