seems to me like the instincts to hunt and work should be there and are rarely taught...However all the training comes in to work cows,goats,sheep,etc. or just kill skunks and possums on the way to finding and baying up a hog.
Other than trash breaking the only other training i have done is if a pup is suicideal it is good to get him backed up and baying in a pin before getting him on an experienced boar with cutters in the woods. Or if a young dog got whipped in the woods build his confidence back up in a baypen with something he can handle..but they have to have drive!
