Pit bulls have come into controversy in recent years, as there has been negative news and even possible legislation associated with the breed. These dogs will only become violent because of abuse, neglect or training that aims to make them aggressive. Because they are among the most powerful dog breeds, fostering aggressive behavior is especially dangerous. They are not generally recommended for first time dog owners but with training and plenty of exercise they can be a good fit for anyone. Pit bulls require a long walk or jog daily that is between one and three hours long to maintain for their health and temperament.
