BoxerLover...I have the same issue with my husky/shep Cody. She was rescued from a very abusive home (male) and WILL NOT allow any man to enter the property without a terrifying display of barking. She barks at men walking by (fenced yard) and will jump up onto the fence with her very beautiful, but frightening to many, ice blue eyes and scares everyone! Oddly, off the property, away from her territory, she is absolutely fine, though a little shy. My male vet can do anyting to her without her reacting negatively. But even my UPS man has resorted to just tossing my packages over the fence instead of waiting for a signature! I know how frustrating it is. But, the advice of the other memebers posted here is well taken. I have to gradually expose her to strangers entering the house or yard. I keep her on a leash, the visitor approaching gradually with kind, soft, positive words. She sees me responding positively to the person. Then the introduction of a treat or cookie by the visitor. After a few visits, she becomes trusting, and many of the male visitors have become great friends. Of course, your visitor has to be someone who is patient and willing to go through the "process!" I think, though, that Cody will forever bark protectively at strangers walking by, especially men. I have thought about anti barking devices too, but I can't bear the thought of "punishing" her any further than she has already been. Those devices cause her to cower and the look of fear on her face is heartbreaking. If she barks, I just get her a verbal "No, barking...It's OK" etc. and give her the "come" command. Since you have this issue off your property as well, I think the halti or gentle leader lead could be very helpful. I know of many guardians who have great success with this gentle means of control. Good Luck! I know what you're going through!
