the wild boar around here, can be vicious......... they have been known to charge at cars, causing them considerable damage, and could easily kill a person, with their tusks, and they will attack at the slightest provocation, or even for no reason, but they are nocturnal, so daytime is safe to wander the countryside.
A neighbour, reared one at home as a "pet", and while quite domesticated, ( and de-tusked) it could easily knock you over in its "friendliness", and was still quite small. but as MKg said, the taste would probably have been quite different as no longer wild.
Do you keep livestock? Having any problems? Want to talk about it, whether it be sheep, goats, chickens, pigs, bees or llamas, here is your place to discuss.
