Need Help Training Puppies

if they stay on the road while hunting then I think the best/easiest answer would be to simply park get out and head off into the woods on foot, get them to go into the woods with you, they outta follow you and eventually go off on their own. Hell I get hollered at occasionally because I park the 4wheeler and get off and next thing you know im 5 6 700yds away just lookin, its nice to get out off the beaten path once in a while. See if that will help, I'm not much for draggin a pig around in the woods for more "mock" hunts, if they know what they are lookin for then maybe just try usherin em towards places you think the hogs may be hidin off the roads.
