I had an encounter with a one-percenter. I stopped and had the bike between the dog and myself. It continued to approach, barking and snarling. When he was about 15 feet away, I squirted the water bottle in his direction. It didn't even reach him, just splashed at his feet. He sat down and continued barking. I slowly started to walk the bike down the road and the dog stayed planted, so eventually I got on and rode away.
