Bubba i agree with you.one evening i was walking with my gsd and a man walked 2 steps behind me.He was stepping in my foodsteps and he made me nervous.When i thought about turning around and curse the hell out of him my dog felt it and turned around and attacked him.They react very much on the owners feelings.They know even better how you feel than ourselfs. If you was nervous your dog knows and react on it. Good point bubba
