If you are interested primarily in hunting, you want to look for hunt test titles, MH=Master Hunter etc.
If you want to hunt and participate in field trials, look for FC, NFC, AFC, NAFC, CFC, CNFC, etc.
Are you looking for a pointing dog or a flushing dog? Most people overlook the flushing dogs, but I prefer these. Both Labs and Springers are good companions in the home and in the field for flushing. Try the following links for information on a couple of recommended breeders. Good Luck.
