Ran from my house up to Flat Iron Park with Cooper. On the way there, a rottweiler came charging out of it's house by us and I panicked. Fortunately it was a sweetheart and just wanted to sniff Cooper's butt. And even if it wasn't so nice, a friend of mine drove by and waved less than 10 seconds later. Ran a lap at the park and Cooper found a ball, so I stopped and made him do some extra mileage. Nothing too eventfull happened on the way back home.
