As we passed by, the dog lunged out and clamped its jaws on our friend's leg. The bite broke no skin, but it scared the hell out of our friend. She told us what happened as we walked on (we hadn't seen the bite), and we were kind of stunned. Then the dog-wielding dude walked up and passed us, munching on a slice of pizza.

Our friend told him to "control your dog, or go back to Marin."

Arguments, the SFPD, and animal welfare after the jump!
