Okay so here’s the deal. In the wild of Australia life is a bit of a power struggle. Sometimes Red Kangaroos (not the cuddly grey kind) are super aggressive, and will strangle or claw animals, and in some cases humans to death.
This guy saw what is presumably his dog being strangled, and decided to go toe-to-toe with a Kangaroo (who doesn’t appear to like it much). They stare at one another for a moment before the Kangaroo takes off into the woods. This dude has balls.
