What should the ring contain?
If we want to use rings but don’t know what the ring should include, there are several options. The most common is when the breeder is a member of an association and receives a breeder ID. In general, a ring contains the following elements: H (country code) 20 (association number) 005 (breeder ID) 26 (the last two digits of the given year, printed perpendicular on the ring!) 01 (serial number, indicating which ring it is).
