I taught Finn to roll over by putting him in a down, and, taking the treat to his nose, and "pulling" it around to his side and around almost to his tail, making him curl a little bit. Then, I pulled the treat up over his back and over to the other side, making him roll over. It's all one fluid motion, though. Finn doesn't like rolling over at all. He's good at spinning, though. I want to try crawl next. I think I'll use Aly's technique.
