Flat land Florida swamper here who moved to these SE Tn mountains 11 years ago. Carried a few of my Florida cow dogs with me up here. I'm down to only one now, but she's still able to keep the freezer full of fresh sausage. No matter how rough the country gets, hogs are still going to gravitate towards bottoms. Find you a road that parallels a bottom and concentrate on that. I hunt National Forest Land here and the hogs like to root up the shoulders of NF roads after a good rain. Concentrate on fresh sign(rooting) in these areas and hunt accordingly. I'll walk my rough cur dog up the roads at daylight and catch my fair share within hearing distance either side. Hot nosed, close range, rough dog that will do it all by herself. Like JDT said though, sometimes I believe a more cold nosed cur that would rig from the bed would be worth it's weight in gold
I wouldn't feed one that would open, but would be more interested in one that would get "piggy" from the bed.
