Boxers are not a vicious or mean dog but it seems that most are pretty good watch dogs. I'm hoping my little 14 week male will develop this. I want him to tell me when a car pulls in the driveway. When do boxers normally start to show this? Dobermans show it very early, Boston Terriers (LOVE EM!) show it later. This is my first Boxer so its all new to me. Thank you!
