Hog hunting can be accompolished with a variety of techniques. Hunting over bait is probably the most popular. A close second would be using bay dogs, with either a bow or gun to finish the animal off.
Gaining popularity is the use of catch dogs, with the hunter then going in only with a knife to make the kill. This might sound a little dangerous and gruesome, and it can be both at times. I tried it recently, and I must say, it is an adrenaline rush.
