As a longtime owner of large dogs: Don't live with pitbulls or pitbull mixes. In their case it's not the owner, it's the breed; and they're all undetonated ordinance.

They are notoriously sweet, clingy and loyal, but they have a 'hair trigger' other breeds do not have. Once they get into their aggressive state, they are simply unconscious of any loyalty or sweetness they may normally have. If you own a pitbull you endanger yourself and everyone around you.
