Pony tricks

Daughter has decided to try and teach Bob tricks. She's watched videos on YouTube and wants him to learn to bow. She does this by pulling a treat down in front of him and between his front legs and towards his tail. He should duck low and extend a leg to get the treat. But what he actually does is bed hisbhead down and knock the treat from her hand with his hoof before gobbling it up.
He's not daft lol!
