Lots of love and time, and unfortunately it will never be completely rehabilitated. You have to understand that a dogs mind and thought process is no where near that of a humans. Although they can be very smart animals. My buddy has a pitbull that was fought and I think its great people like you take them in because a shelter will put a pitbull to sleep within 24 - 48 hours even if its the nicest dog in the world. My wife's uncle use to fight them and even though I hated it ive still seen first hand the damage it causes. Physically and mentally. God bless you brother
