Nope. Did the breeder hunt or advertise they were from a hunting pedigree? To find out for yourself, look at the certificate from the AKC where it shows several generations back on both sides. Do any of the dogs have FC, AFC, MH, SH, JH beside them? This would be an overt sign that your dog comes from a 'working' retriever. This is one thing that a prof trainer will look at when consulting you on hiring them. This simply shows a propensity, or likelihood that the dog has what it takes. It is most definately NOT a hard and fast indicator either way. I do know some trainers that will not accept dogs that are not from a hunting pedigree.
Beyond that, if you want to train her yourself, I think that you can judge for yourself or obtain the advice or someone who can actually observe the dog. I would imagine that most any retriever can succeed as a hunter if their training is adequate. That is where there is usually a breakdown. Some dogs might not rise above the level of adequate, but adequate is, uh, adequate!
I'm confused too
