Good girl Sunny! This reminds me of a cousin's new puppy. She had mastered "sit" but not "come" - when she took off after a bug or something, we started to run after her, and her owner yelled "Sit!" and it was just about the funniest thing you'd ever seen. She was still running, but just with her front paws and her bottom dragging on the ground in her "sit" position. Thankfully it slowed her down enough so I was able to catch up with her and step on her leash to catch her - but I think we were all laughing too hard to scold her!
