Went for an early morning run along the beach. 2.5km out and back. Half way back I see a pack of dogs playing and barking by the dunes (I was running by the water). They see me, come running over barking. I crap my pants a little. When they get close I make a show of aggression by running towards them shouting at them to go away (usually works with solo dogs at my local park). They get angry and surround me. I get bitten on my inside left thigh, my left ankle, my right bum cheek and my right hip. I crap my pants some more and try to run. I slip but manage to get back up and ran a few steps. They stay on me. I realise I'm going to have to fight some dogs. Stop running, start punching and kicking and they immediately, calmly stop and walk off. I didn't land a single blow.
Moral of the story. Punch every dog you see.
