He's still at it? I met him when he was the size of a beer can. Now he almost looks like a pony keg on stilts! Hope he grows out of it. I'm guarding my leg's virtue!
Just play tug of war with him, once. As soon as he identifies you as a potential playmate you will not be left alone. An endless battle for possession of his rope toy is expected! And you really can't say no the little guy anyway.
