There are many MANY other registries in Germany other than the IBC that register purebred Biewers as well as Biewers that breed back to yorkies (as that is still common practice of many breeders in the country of origin)
The BNR is also a club in the States that registers purebred Biewers and I have been told there is one more, however I do not know that as fact.
The BBIR only registers Biewer to Biewer breeding.
