I was once chased down the street by a dog, until I realized the sound was a little too familiar. I turned around, and realized it was my own dog . She was motivated by the chase aspect, she had been around bikes since she was put in a shelter and I adopted her. I went back home, got the trailer, and brought her along .
In most cases, follow six simple rules
1- Stop the chase by stopping your bike . In some cases, this ends the fun for the dog
2-Keep the bike betwixt yourself and the dog. This makes you a more complex problem for the dog .
3- Command in a loud voice- Now you are another yelling human , not much sport there .
4- If there are 2 dogs, target the alpha. He/She will call off off the other for you . Not always the obvious one, either. Look for eye contact and behavioral cues.
5- Study dogs, their motivations, behaviors, and habits. Know your opponent .
6- These stratigems don't always work . Good luck
