I think he knows where those back legs are and how to use them! Look at him go! *If* I keep going with this, we can turn it into a handstand, thus I’m trying to click when he’s lifting both back legs at the same time. But although I’ve taught my other dogs to go up with their back legs on something like this, I’ve never taken it as far as a full handstand. I like the core strengthening work with this. I like the rear-end awareness. But I’m just not sure I want to put the stress on the shoulders (esp with a puppy) for a full handstand.
