I was in rural Japan, and was chased by a pack of wild dogs. I ignored them while ****ting myself, but they finally gave up.
That same week, some dumb**** neighbor had their dogs loose...we ARE out in the country, so I guess they didn't think any further about people actually jogging around. Anyways one of their dogs got REALLY close to biting me (my ass/legs), and I just stopped, turned around, yelled "No!" while pointing my finger at him. lol he probably doesn't understand English, but I'm sure he understands tones of voices. Seriously, at least if you're biking, you have a frame and perhaps a tube pump to work with. You'll figure out SOMETHING in the time of panic.
