Dennis, I don't know if hogs run grown deer. It doesn't, as a human sound logical for them to do so, just because of the way a hog is equipped, but it is possible I suppose. I do know that they will eat deer fawn, and kill does that are down for what ever reason. I would think it more likely that the deer and hogs were running from the same thing, but that too is speculation. We have a BIG hog problem in my part of Texas, and we shoot on sight no matter where we are.
