The only dog I've ever been attacked and bitten by in my life was an Airedale. There are several dog breeds known for occasionally attacking and killing people, very often their masters. Among them are of course the pit bull but also German Shepherds, Rottweilers. Dobermans and Huskies. If we were to eliminate all dogs known for occasionally attacking and/or killing people, there wouldn't be much left. I even know a guy I used to work with that was attacked and seriously bitten by a lab. One thing I know for sure is that there is no animal on planet earth more dangerous, more unpredictable or more likely to kill somebody than another human.
