35,000 fatal dog attacks per year. 1,000 fatal crocodile attacks per year. Less than one fatal black bear attack per year. Around 3,700 fatal car crashes per year. 21,156 murders per year. 20 fatal livestock attacks per year. About 700 fatal plane crashes per year. Somehow a dog is more dangerous than a crocodile, a bear, a car, a murderer, a livestock, or a plane.
