I used to ride my bike along County Route 27 a few years back. This black dog would chase me every time. As soon as I stopped, he became a big mush. It’s hard to know what to do; dogs are unpredictable, and they like to chase things, like bikes. I put hot sauce and water in a squirt bottle. The problem with this, as you’re frightened and watching traffic it’s real hard to get a good shot in.
