I generally don't try to flush them out, I try to sneak up on them, and it works pretty well really..............
Except for last night. I was trying to sneak around a few when I hear a deep growl behind me, ends up I got caught between about 10 hogs and a mountain lion, and it was nearing pitch black with no moon visible, so I decided to sit that one out. Flushing them out or trying to sneak up on them though, either one can be very dangerous. But have a big rifle, bring a pistol or a friend, and you'll be fine. I've never even seen it done with dogs, so I have no idea about that. I'd be too scared to lose one I think, I've never seen less than 7 or 8 hogs at a time, and at most it can be 30 or 35.
