The boar in the forest of dean have been known to attack dogs. One of my aunt's dogs (whos a gentle dog) got attacked by one. So yes they can be aggressive.

They come into my garden a couple of times a year. I’ve been very close to them as well. They are lovely animals but if you want them to be scared of you and to run away.

looks friendly

Watch out, sometimes they charge at people

You're the luckiest guy on the face of the earth. That could have gone real bad.

I would have pissed on it.
