My ex husband was a hog hunter in South Carolina. One of my best horses was an ex-hog hunting horse. He was a very brave horse, indeed. He had to pull the lassoed hogs out of the mud when they were trying to hide from the hunting dogs. They would tie up the hog, put in on the back of a horse and take it to a secluded pen on the farm where it was allowed to calm down. When the adrenaline backed off, they'd shoot it, almost like a sniper, because apparently the flesh is not only foul tasting but also toxic when the hog is highly stressed.
It was all very yucky and terrifying to me, and it's not these animals' faults that they are destructive....they aren't meant to be where they are, and they're there because of people. They are just trying to survive, but nonetheless, they are SO bad for the environment and they are supremely scary! Especially momma with piglets!
