Have you a dog that served as your body guard?

I have a like a half breed female beagle right now named Ashley, she guards the pass directly to my office so no unwanted guests could just pop up without her permission, she is very fierce only to strangers but the most gentle and lovable dog to members of my household especially my children.

We have a yellow labrador, we think he is a very good dog, he performances what a dog normally do, barks and growls when stragners are around. He let us know when he sees somethinging outside in the yard. He listens and does what we tell him to do. We love our dog, I always think he is or we are very lucky to have him as one of our family member

My previous dog was like this. We lived alone only the two of us for her first 3 years of life and she became so very much attached to me! She used to be a clam, loving dog, but when I needed help, she was there for me. One morning, three drunk teenagers attacked me, and my calm and lovable dog became the most fierce beast to protect me. She attacked back the attackers, barking and showing her teeth, until they gave up and left. I couldn't believe my eyes when I saw my calm and gentle dog becoming a beast. But she did it to protect my integrity, even if nobody taught her to do so.
