We went to see Cliff, the dog owned by Megan and Eric. It was at their place, Penny was reserved first, but after 90 minutes of keeping distance and exploration of the backyard the game was on. Penny and Cliff raced around and barked and played pretty rough. Cliff might have been too rough at the end, although Penny did her share to run around and engage. Below is one picture before and two after the play. Penny was quite "done" after the game, but could walk in the evening and next morning.
