I personally like knowing the background on dogs I breed, BUT I always breed for ability first. I don't breed for color or anything else. If a dog will do what I want in the woods consistently, on different tracts of land (public land, ranches, deer leases, etc), by himself or with other dogs, I will breed them .
I hunted with a big red male cur in south Fla that I heard was a good dog and I bred to him based on what I saw in the woods, even though they had no idea who bred him or what was in him. My two dogs out of him just haven't been hunted much , but a guy that owns one of the other pups (there were only 4 pups) said his is the best hog dog he has ever hunted with.
I have seen dogs that were from known breeding lines not produce good dogs and I have seen them produce real good dogs. I think just because a dog may be from an unknown source he shouldn't be banned from a trial breeding. He may be from top hunting dogs and you just may not be aware of it.
But I am one that definately doesn't have all the answers so you may want to use your own judgment!!
