I counted 15

While in the shop today I heard a commotion, turned to look and saw Skitzoid chasing his tail.  I started counting as he made 15 revolutions before stopping.  He paused for a couple of seconds like he was thinking about how to catch it, then he turned and started going the other way.  He caught it in one revolution and gnawed on it for a bit before laying back down.  Crazy dog!
