We raised him from a puppy. I probably am guilty of putting less effort into him than I did our pit-lab (She was also raised from a puppy; I was worried about everything I heard about pits, and fell into the trap of "cute wiener dog" thinking for the little one). To this day (10+ years later) he's still a dominant dog, and the pit-mix is actually super passive, loving on every person, kitten, and dog that's ever come into our home. (though perhaps her lab influence plays a large role in that)
