Vic just turned 2 male GSD we have had him a month He has been trained in obedience and has done bitework. He seems to have high prey drive for balls and smaller animals. However does not bark at strangers or show any sign of aggression i know i dont really want him to be that way but how can i tell if he is ready for action? Is this just calm temperment or plain calm? I had some guys at my house working and he was calm as can be (he was with me) What kind of work do i need to do with him? How can i tell?
