I've hunted wild hogs quite a bit. We used dogs to locate and "bay" the hogs. They might immobilize a pig, but very seldom a grown hog.
That boar ain't gona be still for you. They are very fast, strong, and get awful mean when fighting with dogs. We have sometimes caught
a hog to feed out by using a short rope and tying him up with the aid of dogs.
But, a two hundred pound hog is fast as a snake with his head, so stay to the back of him, and be ready to climb something quick.
Good luck.
