Please discontinue the stereotype that pitbulls are raging. :(
Up until they became a favorite in a bad scene, they were known as nanny dogs. If you get them young and from a non-abusive context and train them well, they're absolutely adoring.
In 2013 the percentage with a proper upbringing appears to be very low in the general population. Stereotype stands. This is very relevant to the "trying to socialize" topic in that trying to convince the general populace that your demonized dog breed is an angel kind of misses the point that a cute miniature lassie is a ridiculous effective people magnet.
