I love shaping too! Neo is very clicker savvy. I taught him this trick too and I call it 'stretch'. I also taught him to lift up 1 rear leg (like he's peeing, ha!) and I named it 'think'. So now I can say 'what do you THINK of the Vikings?' and he lifts his rear leg, hahaha my husband loves it, jk. He's a Viking fan and I'm a packer fan, it's great this trick is also really good for their groin muscles for agility dogs.
