[He backs up and rears up on to his back legs, keeping his butt flat on the ground so he can stand up like a meerkat.]

You want to keep your haunches down, and your tail on the ground behind you so it can keep you balanced, then you can crane your head up. If you want to go any taller than this, you need to have your forepaws on something.
