My Riley would protect me. He has already proven himself. My drive way is a mile long and there was a truck blocking it. I had to sit there a while waiting for the person to get back to move it. I couldn't go around it or go in another way. the way my van was sitting and where the truck was the only place the person could have come from was out of the woods on my property. I didnt see him but Riley at 16mths old came over the seat growling and snapping at the passenger window. It scared me so. I couldn't image what was going on with my sweet dog. He had never ever shown any sign of aggression. then I look up and there was a man staring at me. Riley still trying to tear the window out. The man had the nerve to ask me it he would bite. I said yes he will. i told him if that was his truck he had better move it. Riley didn't sleep in his crate that night. When I let him sleep out he sleeps in the doorway of my bedroom watching the front door. Gannie on the other hand she would show the intuder where everything is. or lick them to death. Pearlie would just bark and Sweetie, I dont think she would notice. She is in her own world She has some very serious senior moments. She gets lost in the house.
