I was wondering...where on your body were you bit?
I have been chased often, and on countless times I just continue pedaling, get out of his territory, and all is well. Years back, I stopped pedaling and tried to coast. Not good. One maingy mutt nipped my heel. Thankfully, he only got a mouthfull of rubber.
Since then, I stick to continuous pedaling. However, on at least 3 or 4 occasions, the bratty monster actually nipped at my rear wheel. I now worry that one may nail my achillies while I pedal.
