Most dogs that chase and bark that I've stopped to confront them seem to get very timid and don't know what to do next. They sometimes go back home or just run along side barking when I continue.
It's been awhile since I've dealt with them that way though. There is one big hound I passed today that was oncoming to me and barking, jumping and straining at the harness the owner that only looked to be about 90 lbs was struggling to hold back as a runner and then me on my bicycle slowly went by.
