8. American pit bull
While many American pit bulls make excellent family pets, their recent history as fighting dogs tarnished the breed’s reputation and led to irresponsible individuals misusing the breed. In the wrong hands, as these people proved, pit bulls can be very dangerous. Despite changing attitudes, restrictions surrounding the breed still make owning one problematic for renters and even homeowners in some areas. American pit bulls are very people-oriented, contrary to some stereotypes, but they do require special attention when it comes to socialization with other dogs and animals.
