Love the picture! Sometimes when Cloud doesn't sit, I gently tap tap tap him above his tail and he'd sit. Noriko learned to sit and lay down by looking at Cloud and seeing that he gets treats. So maybe Noodle can be of help. Tell him to lay down and give him a lil treat, and then tell her to and she might do it. Just a suggestion. Shaking took 2 seconds for Cloud to learn. He naturally wanted to raise his paw when I put my hand out, palms up. GOOD LUCK!
