Thanks everyone! Eve, Henry does the high five and 'other paw'. It's hysterical because he's so long and lanky that he can't sit up on his hindquarters like a shorter dog could, so he rears up like a kangaroo to do the other paw. And Gale, Henry melts my heart every day! He is so expressive and loving, and so tuned into our family. He goes everywhere with us and has never met a stranger. He knows we rescued him; he truly seems grateful.
