Biewer is not recognized by any kennel club including FCI and the German Kennel Club it is only recognized by its own registry and UKC in the US.

I am not sure if I am the right person to comment, but this what I found on the Biewer Breed club of America Inc,

The Biewer, pronounced (Beeva) originated in Hunsruck, Germany in 1984. Mr. & Mrs. Werner & Gertrude Biewer started the first Biewer through a recessive piebald gene occurrence in their Yorkshire Terriers. Although Mr. Werner Biewer passed away in 1997, his legacy lives on through this exquisite rare breed.

The Biewer Breed started with foundation parents "Darling von Friedheck" and Fru Fru von Friedheck". Both dogs were blue and tan and were world youth winners in 1981 at Dortmund. Their mating brought the first blue, white and gold Biewer, "Schneeflocken von Freidheck", born in January of 1984.

Mr. Biewer continued breeding his colored Biewers to achieve their white bellies and four white paws. In 1989 the Biewer was accepted as its own breed with the ACH German e.V.
