Plus six dog breeds each contributed to one death, including: German shepherd-mix, golden retriever-mix, Rhodesian ridgeback-mix, lab-mix, husky and mixed-breed.
To put it in perspective wrt to overall number of dogs, there are about 3-5 million pit bulls in the U.S., 3.5 million German Shepherds and 2 million rotties, so pit bulls kill way out of proportion to other dangerous dogs. Labs are the most popular dog and golden retrievers are number three. I couldn't find numbers for them, but assume they're around GSDs.
