Pit Bulls are not the stereotypical devil dog put forth in media myths. 

Pit Bulls have great physical and mental characteristics that make them excellent partners for responsible, active, and caring owners. These same outstanding qualities can also make them a little difficult to handle for people who don't have a lot of experience with dog ownership. Obedience Classes are strongly recommended for this breed. A well behaved and obedient Pit Bull will be a wonderful companion, and a great ambassador for an often misunderstood breed.

Pit Bulls are very adaptable and will even do well in urban living, provided they have enough exercise or other positive outlets for their energy. Pit Bulls are strong, energetic, agile, and powerful dogs. They are also very resourceful and driven. "Determination" is one of their most notable traits… Whether it is escaping an inadequately fenced yard to go explore the neighborhood, or destroying your new couch when left home alone, or climbing into your lap to shower you with kisses! They just don't give up easily.
Most Pit Bulls are very good with children. However, any dog must be supervised with children at all times. Like other active dogs, they need substantial daily exercise -- and depend on their owners to teach them good manners, such as not jumping. 
Owner responsibility is required for anyone getting any dog. Pit Bulls strive to take on the behaviors that their guardians instill in them, and their behavior is reflective of the care, training and socialization practices (or lack thereof) used by their owners. It is essential for owners to socialize and train their dogs so they are well-behaved with people of all ages and in public situations.
