I've never had to do anymore then yell "NO, BAD DOG GO HOME!". Thing is, chase is a game for dogs. If he really wanted to catch you odds are better than not he will. If you think the dog will catch you get off your bike and hold it between yourself and the animal while telling it to go home. Think about it, a person on a bicycle moving by is a curious unnatural looking thing and most of the time they want to investigate it. Now, 99.9% of dogs know the "No" command, deliberately harming the dog with ammonia or lemon juice only reinforces the idea that cyclists are bad and the dogs pack (family) needs protected from them. Sure, you might get by but what about when 10 year old Suzie pedals by. Will she be able to get away from the dog you taught that cyclists were a threat?
Drive by the house in your car to get it's street number then call animal control and the police if a local leash law applies to your county. You don’t need to confront the dogs owner and you certainly don’t need to harm an animal that is the victim of ret@rded owners.
