Smell is a huge deal to dogs. Keep smells as little as possible. Avoid fabric softener, perfume, cologne, strong smelling soap / shampoo. Shower after every workout or any activity that makes you sweat. Avoid eating red meat / exotic foods before a ride. Keep your BMI under 23.

You'll find dogs are less likely to chase women due to less body odor and less meat on diet. Someone on a bike is less likely to be seen as prey by dog. More often than not, if chased, they see you as a threat

Appearance and movement will also matter. In this aspect, simply try to blend in. If all the cyclists in your area are riding on cruiser bikes and not wearing helmets you'll greatly improve your chance of avoiding catching dog's attention if you also ride on cruise bikes and not wear helmet.. I'm only saying it as an example, not to discourage anyone from wearing a helmet. I wear helmet in all my outdoor rides too even in short 5 minute rides.
