You can get springer, pointer, GSP, who have no interest in hunting, or just plain morons who are more trouble than their worth. I suspect Labs are a better quanity risk than most others. As far as "show" type labs, which is what you are "backyard" dogs, a lot of show people are making a the breed return to it's working heritage. A lot don't know a lot of outdoor lore, or hunt but are commited to the benefit of the dog. I would not rule them out. I have the second of this heritage, my duck club buddies wonder what kinda dog he is? while running around attempting to control the snipey nosed, greyhound-est, hyper, "field" dogs, who had a FCH about 6 generations ago, and live in permanantly in a kennel in the off season, because you can't stand them fussing around, and you wife likes the couch.
