Actually that (see above) is just what I was thinking. Dog nows equates a bad feeling with chasing bicycles. Next time he'll think twice about chasing one. If all dogs got hit with HALT (I don't even know what it is) or Pepper Spray when they chased a bike then they probably wouldn't chase bikes anymore. By the way I like dogs a lot so I'm not just one of these guys that's afraid of them or anything.
