• Biewer Terrier Registry of America - BTRA who call the breed "Biewer Terrier"

• The Biewer National Registry - BNR who call the breed "Biewer a la Pom Pon"
• BYA - Biewer Yorkie Association
Since this was a new breed and no one knew what was to come, the Biewer Yorkshire Terrier was also part of:
• Rarities INc & NAKC – A conformation show organization
• The American Rare Breed Association
• The IABCS – A conformation show organization
• The Rare Breed Network
• The National Canine Association
In 2009, the Biewer breed signature was created by Mars Veterinary. The breed standard was then drawn up based on scientific data as opposed to data derived from pedigrees, which makes this a very unique situation.
It was not until 2014 that the Biewer was added to the AKC's Foundation Stock Service.
