"Grand Champion" is a bench title (show dog). Bench Titles mean that the dog is very pretty and fits the 'conformation' requirements. Bench Titles have nothing to do with hunting abilities.Not all, but the majority of show dogs aren't that great as hunting dogs. There have only been one or two bench dogs that have ever 'made it' in the Field Trial or Hunt Test venues in all history.
What most prospective buyers (for hunting dogs)will want to see are lots of Field Titles (not bench titles)like the following: FC, NFC, AFC, NAFC, MH, MHR, HRCH etc etc(or the Canadian equivalents) in a 3 generation pedigree.
People that are truly "in the know" will also want to have proof that both dogshave OFA or PENN certificationfor both hips and elbows. Also CERF certificationfor eyes.A test for CNM (myopathy)has just become available, and serious breeders arenow doing that as well. All breeding dogs should be tested for Brucellosis (a canine sexually transmitted disease) within 30 days of breeding.

By the time you spend the $$ for all of the desired tests, you'd never make any profit, especially if there aren't many Field Titles in the pedigree, because the pups wouldn't sell for very much money at all. Then you have to consider the health risk to the female, puppy shots, dew-claw removal, 26 month healthguarantee on the pups (and what will you do if one of the pups has hip dysplasia ? ) Take it back and refund the money? Promise a free pup from the next litter?

Without Field Titles and all of the health clearences and a writtenguarantee, it would be very difficult to sell these pups, even if they were cheap.
