Here is some information that will help understand AKC pedigree designations.
FC = field Champion
NFC = National Field Champion (only one dog a year earns this title)
NAFC = National Amature field Champion (again only one dog a year)
AFC = Amature Field Champion
MH = Master Hunter
SH = senior Hunter
JH = Junior Hunter
Of these designations FC and MH, SH are the most important to a hunter. Guys like you and me don't often get the chance to buy out of an NFC/NAFC (you need to know someone to even learn about these breedings). Remember the dog and the bitch can both add equally to the gene pool. Generally females will not be as highly titled as they don't compete or train as much due to heat cycles (in season bitches cannot compete) and time lost to breeding. I like to see at least 7-8 or eight titles in the first three generations. A CH on a pedigree is at least irrelevant and maybe even a bit of a red flag when picking a hunting puppy.
Also never choose a puppy based on how "cool" the breeders web site is! Judge the breeding by the content of the pedigrees! I have said this before and irratated one of the mods here, but I stand behind my feelings. Breeders breed, Salesman market.
Every thing I have said means absolutly nothing if the health clearances are not their. Hips, elbows, eyes, EIC etc are all hugely important.
UKC has deisignations that are similar. I am not exactly sure what they are.
I hope this helps a little
