I would suggest you check out this link for The North American Versatile Hunting Dog Association
http://www.navhda.com/ they don't have stud books for setters however do allow them to test with NAVHDA. They do testing not competition. Each dog is rated on its own performance and not against the other dogs that are entered in testing. If you can find a pup from a mother and/or a father that received a Prize I from NAVHDA in the Natural ability or Utility test you are talking about a good sound dog, and a Prize II will most likely produce a fine hunting dog for the average hunters needs.
Good luck to you on finding a quality dog.
