mother nature does not make mistakes when she culls...her rules never change. Humans as breeders have a wide range of views as to what a good hog dog is. What some call hog dogs others cull those same dogs.
The only time to breed a cull is only one time from a top line of dogs and that dog should be related to the dog being bred. Then select the best pups from that cross. It is better to do it that way than to outcross a good dog from a strain to an unrelated good dog.
I haven't hunted much anymore but I saw lots of dogs that could not find a hog and have seen a whole pack of dogs crossover a fresh hog track that did not interest them. I don't think that it has changed that much this fast... but lots of good information on here so there is no excuse as to why we can't breed better dogs.
one hunter likes an open dog and another wants to cull the same dog.
one hunter likes a short range dog that if the hog does not get bayed or caught in 3/4 mile to give it up and come back...the hunters that do this either are poachers are care to not tresspass.
Then the other type of hunter that culls a dog if he quits the hog...the hunting plots are getting smaller so this long range dog is in jeopardy of getting shot, ranned over, or stolen.
I can see where dogs should get better because of the vast information out there for the folks who want to breed better dogs but then we have the variability in how we interpret this information or what we think a good hunting dog should be.
We just need to be more in tune with mother nature about some things
