Totally get this. People know to be wary of wolves, but they think hogs/pigs are "cute." It's not a Charlotte's Web story.
Growing up on the farm, we kids were absolutely aware that we were not to get in a pen or a field that had hogs in it. There are stories of farmers who were putting out feed for the hogs having a heart attack or other medical emergency and the hogs ate the feed and the farmer.
