According to a Forbes article that rates dog breeds as potential insurance risks for homeowners, the 10 most aggressive breeds of dogs are Pit Bulls, Staffordshire Terriers, Doberman Pinschers, Rottweilers, German Shepherds, Chows, Great Danes, Presa Canarios, Akitas and Alaskan Malamutes. Though lists of aggressive dog breeds in various media are not always identical, a majority of these breeds appear on most lists.
A report published by the Centers for Disease Control and Prevention on dog-bite related fatalities from 1995 to 1996 specifies that the most commonly reported breed involved in fatal attacks was Rottweilers. A CDC study on fatal dogs bites from 1979 to 1996 published in the Journal of the Veterinary Medical Association singled out Pitt Bulls and Rottweilers. Media attention focused on these specific breeds and others considered highly aggressive has led to a controversy about breed-specific legislation, or special restrictions on ownership of certain breeds of dogs considered dangerous.
An article by the American Veterinary Medical Association points out that breed-specific legislation does not solve the problem of aggressive dog behavior. Any breed of dog can become aggressive and bite. A CDC web page on dog bites points out that following certain safety procedures when around any dog is the safest way to protect both adults and children. These precautions include not approaching unfamiliar dogs, not running from dogs or screaming at them, remaining motionless when confronted by an unfamiliar dog, avoiding eye contact with a dog, reporting stray dogs or dogs with unusual behavior, and not disturbing a dog that is eating, sleeping or protecting puppies.
