Chewy likes to stand up on his hind legs (especially when a treat is involved). At first, we tried to discourage this behavior and have him sit for treats. However, I decided it would make a good trick, and started putting it on cue.
Chewy reminds me of a bear when he does this, so, I named the trick dancing bear.
Chewy is starting to offer me behaviors already while we're training. Yesterday, while in a down, he scooted himself back a bit. Really hoping I can shape him to crawl backward.
He also pretty much taught himself the "look at that game" with the vacuum cleaner (while it was turned off). Not only was he looking at it, then me, eventually he started running over to it, touching it with his paw and coming back to me! It was so amazing to see his little (and I mean little) brain working.
