> There is a standard paragraph which just states that the endorsements have been placed permanently for the life of the dog. It is sold as a pet and is not to be bred from or exported.
Then I am afraid the breeder is within their rights, but to my mind as a breeder rather short sighted if the bitch is of quality enough to gain her stud book number then her genes might be of value to the breed (a lot depends on how numerically strong the breed is).
I would have thought the breeder would like to see good examples of their breeding go on to make a contribution, (but not feel entitled to have such a tight grip on things) as few of us can keep every good puppy we breed (or often find we have let go better than we kept).
Mentoring a fledgling new breeders is a big responsibility and can be quite a lot of work, but ultimately what breeding is all about passing on the baton of breed custodianship to others, as my mentors have tried to do for me.
I am assuming the bitch is young? If so I would in writing explain that you are happy to do any required health tests, and for the first litter use a stud from a shortlist they recommend, but wish to breed the litter in your own name and not be so restricted as their suggestion would entail, and that you would like the litter bred in your own name as you will be taking full responsibility for the puppies produced, both costs and morally, and agree to appropriately fully endorse any puppies bred.
If they agree IN WRITING then go ahead and get the health tests done and continue to show your bitch to further good results. Having the agreement to lift endorsements on health testing results (make sure the agreement stipulates what are acceptable results for example hips/elbows/hearts below a certain score, eyes clear or DNA clear or Carrier).
I could understand a breeder not being willing to lift endorsements on a DNA tested carrier, as ti takes knowledge to breed from them so as not to inadvertently produce affected offspring. This is the only scenario where a breeder in my view would be justified to want to do as your breeder wishes to, and keep full control.
Unless you get an agreement as above from them I would continue to show my girl and look out for a planned litter that you would like a puppy from with fewer strings (perhaps by the sire of your bitch or similar liens), and make it quite clear you are doing so, you never know in another six months or a year the breeder may be willing to be more reasonable..
