Junk it

The whole idea of breeds is silly. It is dog show stuff. It is belief inspired by purebred ideology.

Breed dogs for their use. Coat and size are a factor, but not breed.

Are your field bred working setters getting too inbred?
Why breed them to a bench setter?
Breed them to a field bred working pointer.

Do you hesitate because then the puppies would have no "purebred papers" and it would be easier to sell 1/2 working setter, 1/2 bench setter puppies, with papers, to the fools who would buy them, than to sell pure working field bred pointsetters?
