Georgia also allowes it.
It really depends on who's dogs you are running. Every group has their own system and preferances. The group of guys I know will typically have 2 types of dogs, Bay dogs and Catch Cogs. The Bay dogs are released first and typically consist of Cur's. The catch dogs can vary a bit I have seen American Bull dogs, Cur's, Pitbulls, etc.
What usually happens is the Bay dogs are released first. The Catch dog (dog's) is kept on lead. The Bay dogs track the hog down and get him cornered. Once the hog is cornerd and the huntes get close enough they will release the Catch dog (dog's). Thats typically when all hell breaks loose. Once the Catch dog, which usually go for the ears, has hold the Bay dogs gain a little curage and they will start grabbig the hog.
Once the Hog is trapped you can go in and grab the hog by the back legs and flip him over on his side. You put your knee in his neck and stick him behind the front shoulder into the heart. I have seen them stick them in the neck as well. Don't go grabbing the front legs, other wise he may spin and cut you.
The group of guys I know use to catch them alive if they were of good eating size. They would duck tape there legs and mouth shut. Take them home and put them in a pen. Feed them out and de worm them for about a month and sell them.
