I think someone nailed it early in the post...most hog hunters don't want to pay the money it would take to get a ben dog. Most of the people who have them are probably cow dog people..I would also suspect that lots of dogs out there have a little ben in them and most don't know it. I want to know all the history on any of my dogs, but find most hog hunters (from my dealings) just want a dog that will hunt and don't want to waste space in their head to have to remember the where and the how
