A man courageously punched a kangaroo that had his pet dog in a headlock.

The viral footage shows the pet owner sprinting over to the wild animal before giving it a right hook creating a video that would go massively viral.

A post shared by the video's owner read: "A group of hunters gathered to help a young man with terminal cancer achieve his last wish of catching a wild boar with his hunting dogs.

"While hunting, one of the highly trained dogs was chasing pigs by scent and collided with a big buck kangaroo. The kangaroo held and wrestled the dog by its protective gear (boars have tusks like knives).

"The owner was horrified that his dog or the kangaroo would get hurt and ran in to save both parties. The dog tries to escape, and the kangaroo releases the dog when the owner gets close.

"The buck kangaroo shifted to attack the human, and a kangaroo kick to the guts could easily disembowel a person. The man backed off to give the kangaroo some space, but because the kangaroo kept coming closer, the man punches the kangaroo’s snout. The punch stopped the kangaroo from advancing another attack and gave the owner and the dog time to disengage from the big wild animal.

"The kangaroo hopped away and we laughed at the absurdity of the situation and how unfortunate it was for the dog and kangaroo. The dog’s owner felt no malice to the kangaroo but had to step in and fix a bad situation before it got worse.

"Unfortunately, the young man, Kailem, lost his brave battle with cancer, so this hunt is part of his family and friends’ treasured memories."
