Not all dogs are dangerous, but some breeds are more frequently involved in serious bite incidents. This ranking, based on fatal attack data, hospital records, and bite force studies, shows which breeds pose the greatest risk when improperly trained, socialized, or managed.
Here are the 10 most dangerous dog breeds according to real stats, ranked from least to most dangerous.
