A boar

[MarkP]

I heard a story from a reputable source and confirmed by the victim himself where a pig turned the tables on a dog and chased him back to the owner. On the way past the pig hooked the owner in the groin, compromising some major blood vessels. He would have died had his wife not been a nurse. She reached inside his leg and slowed the bleeding otherwise he might not have made it.

I don't think it was a hunting situation, just a dog scaring up a pig with unintended consequences.
