Are they actually not happy to put you on a list or is it htat there are too many people ahead of you on their list for the puppies available. If it is the latter case all you can do is choose the breeder you really want to go with and wait. Book with just one breeder and ask him/her to let their freinds keep you in mind should they have a cancelation etc. that way you will be taken seriously, as in numerically small breeds people who try to book with lost of people tend to be viewed as timnewasters.
If they won't consider you at all is there perhaps a reason they could possibly see you as unsuitable. I am not being unkind, but maybe your family circumstances, work commitments, accomodation, other dogs owbed might not make you the ideal owner when they can afford to be fussy?
