Arizona man David Yanito has a very clever dog called Koki. As he describes, everything command that Koki knows he learnt in under 15 minutes. Watch as Koki is told not to peek in this video and knows exactly what to do. He cutely covers his eyes with his paws, eagerly awaiting the surprise that David says he has for him. This great footage highlights the humour and intelligence of the canine species. Credit: David Yanito.
