The H20squirt works for the small/medium FDA(Friendly Domesticed Animals). If not then the yell works.

The Larger FDA, or the non tags are a different subject around my neck of the woods. Pedal,pedal,pedal is what I have used. But the last encounter, I used an old bmx move. I did a kick out shoving the back tire in the mutz general direction and, whoh it worked and I could still pull on off. Thank god for mtn bikes.
