ASK THE JACKAL

A dog swimming with sharks in Australia turned the table on the man eater, biting the shark on the tail as both swam near a shore.

We have the video below from YouTube and it is quite humorous, and as an added bonus narrated by a man on the beach who shot the now viral video and is amazed at the dog's actions and the fact that he caught it all on camera.
The pooch dives underwater and bites the shark a few times to move it along. He and another dog then make their way back to shore.
