What could be done for dog owners to become more sensitive to people feeling a little uneasy about dogs?

A dog bit me when I was 14. In general, I like dogs, but there’s always this feeling, well, you never know… I don’t like it when unleashed dogs are chasing me on a bike with the owners yelling, don’t worry he’s such a nice guy, he won’t harm anyone… yet the dog continues to ignore the commands to go back toward his owner.

Maybe this is why I’m a cat man. Cats don’t do that.

I know many dog owners are very sensitive already. What could be done to reach out to the rest?
