If a dog gets near me, I stop the bike and place it between me and the dog assailant. If there is an owner I let them know in no uncertain terms I am not interested in making friends with their pitbull or Muffy the picadoo. If it continues to approach, it could get ugly. Four broken bones and a resulting stroke has significantly adjusted my attitude toward dogs and their irresponsible owners. I will not be a victim. Attempting to outrun or out maneuver a dog is a foolish thing and is just a good way to get yourself hurt, if not the first time, eventually.
