It is advisable that you send the breeder a gentle reminder that you have not yet received one.
Also make sure that they have all the information they require from you — Correct spelling of your name as should stand on the Certificate of Origin, the name of your terrier, and a postal or email address to which the certificate can be sent to.
If, after repeated reminders, the Breeder does not get back to you on the matter, you can lodge a query with the Breed Records Officer (email@example.com).
We ask you to please remember that for most of us breeding is a hobby that originates from our love of the breed, and all of the National Committee members are volunteers. Thus real life can ensnare us and keep us from completing necessary paperwork on time. Also consider that displaying anger will not hasten any processes.
