I work over in Walnut Creek and I was on lunch, eating outside Chipotle. I was sitting there eating a burrito, and out of nowhere these 2 pits without collars come sprinting down the sidewalk. They chased each other for a while, then the female ran off and the dude kept running around in circles not sure where she went. Then he started running in random stores, this furniture one twice, then he hit up starbucks and chipotle, pretty funny. Everyone was freaking out cuz they were big ass dogs, and didn't even have collars, prolly thought they were about to snatch their children right out of the stroller.
