Dogs can be trained to do some really clever tricks as shown in a video where three herding dogs were coaxing four ducks to go through a hula hoop and then under a girl doing a back flip.
In the video, we can see the three dogs – Roy, Lass, and Celt – surrounding four ducks as their trainer gives them the signal by his whistles. The ducks in turn waddle toward the path the dogs set for them. -via Geekologie
