If you could have only one dog...

if I were going to hunt 1 out, I would want a dog that preferred to work alone ( independent) medium to warm nose, enough bottom to stick with a runner, enough baying ability/ grit to stop a hog that wanted to fight, enough handle to stop and come in when I called them off, and enough intelligence to catch hogs they could catch and bay what they couldn't catch.

I would invest a lot of time scouting to try to put this dog into hog sign. I would spend a lot of time with the dog in the pen and in general working on handle.

These dogs exist BUT they are scarce. You are embarking on a path less traveled. I admire your willingness to try it.

Search crackers ( his Monkey dog fits your description) Warrent, Florida Curdog, TazD, and Blackstreak on this site. They seem to hunt a similar style to what you are looking for. Good luck. Keep us posted.
