I no very little about pigs; a little disclaimer to start.
But my gal acquired "the cutest little Viet min pot bellied piglet"

After I got over being PO'd at yet another animal on the acreage...he's pretty cool
Things I've discovered about him ( indubitably a full size feral pig would eat his lunch of course).
Cold does not bother him...and he's Vietnamese for christ's sake!
He is
very tough. We've a St Bernard / Great Pyrneses X that tries to kill him whenever she can. Much growling, barking and squealing, but no blood...yet. We keep them separated but I think Winston(his name) would rip her open with a tusk eventually. And the dog is half Pyr...do a google search on them, they are coyote killers. It's been claimed they'll handle big cats and bears but I'd think training will be req'd for that.
Pigs seem to be tough enough to handle extreme cold and big dogs ( coyote killing dogs to boot)determined to tear them a new hind end.
And they are fast! Winston's legs are like 10" long, lol. I dare you to catch him when he's running.
And this is a neutered around the yard pig, not a full size feral pig!
I'm glad we don't have them in my country; like rats, not welcome
