After I got home this evening, I was hanging out with Mr. Dodger. He had his cone off, so he could groom a bit and be more comfy. He only enjoys that luxury when we can watch him, so he doesn't mess with his leg.
As he was standing, watching me go through today's mail, his right ear apparently started to bother him. So he slowly brought his back leg up and gently scratched at his ear. It lacked the usual vigor he would bring to such an effort, but he got the leg up/forward like he hasn't since the surgery. It was a wonderful sight!
He's still not walking on it, but I think he's making progress!
