My dad always told me that Boar hunting is very dangerous... Their large and surprisingly quick... and you have to carry a sidearm in case they catch you off guard and start charging towards you.
They can gore you. Their teeth are about the size of your tumb and sharp, and the have tusks sticking out of their mouth. They also weigh looks near a tonne full size, so they can also trample you.
Boars charge straight, and their momentum reduces their turning capacity at high speeds. Run in big circles and you can get away, but they are fast. People would pay to come hunt them.
