I will not be of much help. On my rides it is never just one dog chasing me. It is at least two, so I am reluctant to get off my bike. Yelling commands for me helps (Go on!!) but I will be hoarse by the end of my ride. I hate to stay clipped in as I might need to stop, but the time I twisted to unclip, the dog had my whole ankle in its mouth. Ouch. I guess it was an agressive move? I usually have little time to unclip before they are upon me.
