The Biewer Club has now backtracked and now call them Biewer Terriers not Biewer Yorkies. They are not currently recognized as a breed by the German Kennel Club nor the FCI under whose rules for shows most clubs in Europe compete for their titles, nor does the AKC or Canadian Kennel Club recognize these as a breed.
