Dogs aren't the same at all. Even the same bread can grow to be different depending on the circumstances of growing up. I've seen it again and again and again until I got tired and accepted it.
As for humans, whoever try to customize your behaviour in a way, fuck him. When the state wants you to act in a certain way, it's an authoritarian one and you gotta, through your whole life, defend your self and the way you behave and think.
