Chaos, come here, boy!

I've been training Chaos to come when called using clicker training. Basically, you get the animal to associate the clicker with good things, like food, and then whenever he does what he's supposed to do, you click for him and give him a treat. You then slowly start eliminating the treat and just clicking for him, because the click has become a convincing reward...of course you still throw in a treat now and then.

It seems to be working, at least at short distances. I haven't tried calling him when he's all the way across the apartment and really busy terrorizing a plastic bag yet.
