March 2012. Blue was about 2 yrs old. He is one of the most well behaved mild tempered pit bull I have ever come in contact with. Because we have had him since he was very young he has had proper training and positive socialization. He shows no aggression even being rescued from a large city known for dogfighting and strong bloodlines. He loves to play with all animals and will not even join a fight that starts in front of him.
