A month or two ago I was on a club ride with my lowracer, and a dog came out at us. Being the lowest, he fixated on me and was not giving up. The others were worried that I was wandering out into the middle of the road with a car coming at us, but my plan was to lead him into the oncoming lane, with me in the shoulder, and let the car take care of him.
Too bad he gave up the chase before the car got the chance.
