OK fellas, here's my take on the whole aggression issue. Why do you neuter your dog?? To prevent him from running, and well being aggressive. Now you take the male hormone testosterone that makes us men and also makes us more competitive and aggressive than females and supplement it with doses that are well above your normal hormone levels and tell me roid rage is a myth?!?! BULLSHIT!! It is VERY real, granted it's in your mind and controllable, but you will become more aggressive. You can control it, but it is a very real situation.
