I hear alot of stories about dogs losing their aggression after being neutered. I guess my question is: exactly how much aggression do they lose? I have an appointment to get Cody "taken care of" and am a little nervous? Is he going to be a complete wuss after this is over? Right now he pitches a holy fit when someone comes to the door and I LIKE THAT. Will he lose this watchdog mentality? He does not attack animals or people, and obviously we don't want him to. However, I do want him to continue to stand his ground when strangers come to the house. Thank you for your thoughts!
