Can I get any words of wisdom?
I don't think we have done anything to encourage her. It has never been a behavior that I have wanted her to have. When she first started doing it we would call her back and most of the time she would just ignore us so we would take her inside kinda like a "time out." She have also held her muzzle shut and tapped her on the nose and said "NO." I would rather not get into what doesn't work but concentrate on a new way that will.When you say "she is too protective of us" is that something you've kind of encouraged around the house...ie; allowed her to bark at strangers, charge the fence?
In other words, let her make the decision of who's scary and who's not?
What have you done to teach her that this isn't her job?
