What I have learned from my personal jogging experiences:
1. Wear yellow so you will be seen by passers by (I jog at night).
2. It's embarressing when your running with your dog and he gets tired so you are now dragging him behind.
3. It's even more embarressing when the dog gives up and rolles over so now you actually have to pick him up, and jog off balance with the dork.
4. Wear layers so you can remove the yellow once your done being embarresed by your dog.
