Many, many, many years ago... the joke was "If you think you've seen a good yellow run... it's because you haven't watched enough blacks." I believe good breeders have brought forward a robust population of yellow labs and that rhubarb is no longer true. When I first started paying attention to FT's (before there were hunt tests) there were no chocolates of any repute. Look how that has changed!!!
To the OP... just get a good lab with a working pedigree. Please do some study on the differences between the labs bred (predominantly) for conformation shows, and the ones who have (at least some) hunting retriever and/or field trial progenitors. (The world of labs is so polarized, they might as well be different breeds altogether.) If you want a hunting dog, don't go to an exclusively show breeder. There are some determined breeders trying to bridge the gap. But just study up on the pedigree of any litter you like.
