> We want to be responsible and have correct health checks done
The first post you got was not a grilling but giving you the facts.
Responsible bitch owners choose the males that will be bred from. the males owner can let the breeders know of his availability, usually by advertising in breed club publications, and breeders may then consider what is available.
they will pick a male that they have seen, have knowledge of his health, his background (his parents etc) and often have seen the quality of the offspring he ahs produced.
Of course every dog used has a first time, and often this will be someone who knows his parents lines well, and is willing to take the chance on an unknown quantity.
I have a breed that is numerically small, yet even champion males sometimes rarely or even never get used, as there is also the issue of whether a particular male will make a good match for the available bitches. He may be too closely related to them, not have the qualities that the bitch needs, or that appeal to the breeder.
All this is moot unless a large cross section of the reputable breeders don't see him, and for your breed that will mean at shows, as that si the place breeders see the most fogs of their breed in one place to make comparisons.
