Last time I dealt with a dog was fairly amusing. Little yapper of a scotty dog, and i'd had it bark at me before, so I knew where it lived. I come riding by with my wife at a somewhat lazier clip and the scotty comes boiling out barking and snarling. I look over and bark back, snarling and weaving a bit toward it.
Dog stops in its tracks with a "wtf?!?" look on it's face and sits down.
Haven't seen it again since.
