"A dog accidentally shot his owner during a duck hunting trip in Minnesota Sunday morning. 

The hunter was out for waterfowl with his dog on the Leech River in Cass County Minnesota, hunting from a boat.

Police say the dog jumped in the boat and landed on the hunter's shotgun, causing it to fire and hit the hunter in the leg"

I think PETA might be onto something with this 'no pets' attitude ~ seems like it's a risky business!
