I've been hog hunting for over ten years on my own now and can count on both hands how many hogs I've stuck with a knife, over. 90% of the hogs we catch are released unless we're hunting a spot where they are staring to become a nuisance then we'll bring them out and put them in my 6 acre pen or my buddy's ten acre pen to mess with pups, we don't allow more than 3 dogs at a time in there and if a hogs gets a lil tore up I let it out behind my house where we'll catch it again in a few months, if we catch a boar we'll cut him and put somebody's mark out of our group on him I don't care if he is a dog killer or not it's the just the way I was raised and taught, we keep everybody's freezer full of ground meat sausage and pork chops and NEVER kill what we don't intend to eat
