''The loudest bark wins, and [the dog which is] most consistent and doesn't stop until you tell it.''
Flynn, who was competing for the first time and was watched by his dad, Marcus Nurse, was ''excited'' to win.
Marcus also competed in the event's whip cracking competition, a title which he won.
Days spent working as a stockman in the Kimberley, Western Australia, set him up well for the win, which ultimately secured him a Svord knife.
Marcus, who is now a local rural real estate agent, plans to return to the event next year with Flynn and younger son Samuel (8).
''I might take Fang,'' Flynn said, referring to one of the family's other working dogs.
Although Belle and Flynn have developed a bond, the youngster plans to let Samuel compete with her next time instead.
''The Fairlie bottom pub bark up was a great community event,'' Marcus said.
He plans to support it again next year, not just by entering, but by spreading the word, encouraging more children to take part and drumming up sponsorship.
