The Western Bulldogs have thrashed Port Adelaide by 90 points in windy and cold conditions at Ballarat's Mars Stadium on Saturday afternoon.

The Bulldogs mastered the swirly breeze far better than their interstate opponents, with the Dogs' seven-goal-to-two third quarter into the wind highlighting their dominance of the game.

The Power never really threatened at any stage with the Bulldogs winning 20.11 (131) to 5.11 (41) in front of an intimate crowd of 4,814.

Key forward Aaron Naughton stood tall with an equal game-high three goals and seven marks. Naughton was joined by Tim English, who pushed forward from the ruck to hit the scoreboard with three of his own and Bulldogs skipper Marcus Bontempelli (three goals, 23 disposals).

The Dogs had 11 individual goalkickers and notched their highest score of the season in the comprehensive victory.

Zak Butters (24 disposals, six clearances) and Connor Rozee (29 disposals, 577m gained) toiled hard for the Power on a day where highlights were few and far between for Port.

Dogs veteran Adam Treloar made a successful return from a calf injury, playing his first game of the year and finishing with 27 disposals and a goal to his name.

A sensational goal from the boundary to star Ed Richards started the scoring for the second term and put the Dogs in front for the first time.

The midfielder's goal sparked a run of five unanswered majors for the Dogs, which included one to defender Luke Cleary who kicked the first of his career.

The Power's attempts to get the ball forward were quickly thwarted by Bulldogs defenders James O'Donnell and Rory Lobb (both eight intercept possessions), who owned the ball when it got to the centre of the ground.

Their intercepts, with the assistance of excellent ball users Jason Johannisen (five inside 50s, seven score involvements) and Bailey Dale (31 disposals), continually sent the ball back into the Dogs' forward line.

An end-to-end goal to Naughton made it six goals for the quarter and the Dogs went into the main break with a 26-point lead.

Port finally got on the board when spearhead Mitch Georgiades goaled, and milestone man Sam Powell-Pepper, playing his 150th game, also scored to give Power fans a glimmer of hope. 

But as soon as the Power lifted, the Dogs went up a gear led by their heroic skipper Bontempelli.

Bontempelli kicked two goals in quick succession, including a lovely left foot snap from near the 50m arc, making it look effortless despite the testing conditions.

The bite had well and truly come out of the game in the final term when the Dogs continued to add to their tally.

Bontempelli kicked his third, as did English among a five-goal-to-none final term for the winners.
