Roundball, Birddog will confirm this, I hope: here in the southern Appalachians, hogs weren't something you walked up to a throat-slit...from the 1700's on, hogs were turned loose in these (then)chestnut, beech and oak forests...they fattened up on mast. At an at-least annual, roundup, the shoats were marked by ear cuts denoting ownership. When hog killin' time came, you went out and shot your hog...there was, and still is, an etiquette is you shoot someone else's.
For example, I shot a boar a couple of years ago (using a Winchester 94 in .30-30 well, it weren't black powder, but John Wayne would have used one)...the first dog on the scene was not mine, so I grabbed him when he got to the carcass, let him chaw on it for a second, and made note of the owner's name. Then I gave half of the meat to that dog's owner. That's how it is done when the dog involved isn't yours, and is an outgrowth of what you did back in the open range days...NC changed its open range laws back in the 1960's. The ending of new pig blood coming into the gene pool has caused the hogs to become more and more boar-like. Hank
