I ride country roads all the time and dogs are a nuisance. Fortunately, I know where most of them are after riding this area for so many years. However, if I meet a new one and don't know their intentions (running with, or biting, me), I wait until they're close enough and then I make a little swerve toward them. They usually have to change course and that's enough time for me to sprint away. I've also "squeezed" them into the path of stationary objects (parked cars, mailboxes, etc). They see it coming and stop or slow down so they don't hit anything, and it usually changes their minds about the chase.

Some of these dogs, though, are my regular training partners and I wonder where they are if I pass by without being chased.
