This is the hilarious moment monkey started fighting with a rooster while a confused dog watched them.

The owner of the animals, Nguyen Hoaii, recorded the video in front of her house in Gia Lai, Vietnam on July 27th.

She said that at first, she saw the pet monkey playing with the rooster's feathers so immediately grabbed a chance to capture the footage.

However, she was surprised when the one-year-old chicken became angry and rushed to the six-year-old monkey, named Duck .

She said: "My pet monkey is really naughty and the chickens are serious, that is why they are always fighting.''
