Holiday traffic was tied up for an hour when a small mixed breed dog darted along the busy Stevenson Expressway  in Chicago. State police troopers, road construction workers and passersby all attempted to catch the dog to no avail. It wasn't until he wore himself out and laid down on the grassy shoulder that nearby resident Jose Terriquez could grab him. In watching the video, I couldn't help but notice how the would-be rescuers were chasing him down, hoping to catch him. But anyone with a dog knows that most of them can easily outrun a clumsy, two-legged person, especially if the dog is scared. In an emergency, the best way to catch a dog is to run away from him. The motion grabs his attention in an instinctive way, an urge to chase prey. Unfortunately, our instinct is to give chase, which puts pressure on the dog and moves him away from us.
