The Western Bulldogs have defeated Collingwood by 18-points, to hand the Magpies their first loss since Round Two.

Compounding last week's injury woes, the Dogs lost another two players to injury in the opening half, but fought on to run out 15.10 (100) to 12.10 (82) winners under the Marvel Stadium roof, soundtracked by a vocal Pies crowd.

Marcus Bontempelli's sheer will to keep his side motivated was enthralling, as the captain finished the game with 38 disposals, 10 clearances and two goals.

Meanwhile, Sam Darcy (three goals, five contested marks) was the star inside 50, to dominate the air in attack and do the damage on the scoreboard.

Despite giving up four of the first five goals of the game, the Dogs kept the Pies within arm's reach for much of the game to be within striking distance late.

Daicos (32 disposals, 16 clearances, two goals) set the world alight, breaking Collingwood's clearance record in the process. His work through stoppages was one thing, but his spread from the contest exposed the Dogs for a lack of defensive accountability at times.

Bontempelli attempted to limit the young star himself in the third quarter, but the team-first mindset of other Pies – particularly Lachie Sullivan – impeded the Dogs captain's efforts.

Both donning the bright orange boots, Daicos and Jack Crisp started the game at a blistering pace, the pair combining for 15 disposals, 10 contested possessions, and two goals in the first quarter alone.

With those two leading the way, Collingwood looked in control. Exiting stoppages with ease, attacking directly, and neatly cutting through the Dogs' defence. But it couldn't put a gap on the scoreboard, converting only five goals from 12 scores.

When the Dogs won control of the ball, they were deadly in front of goal. The Pies' kicking efficiency went downhill in the second term, and the Bulldogs capitalised on the turnover opportunities, enjoying a five-goal quarter of their own.

Adam Treloar (37 disposals, 11 clearances, one goal) continued to lead through action in the middle, and emerging Dog Riley Garcia (21 disposals, four tackles) offered a spark through the contest.

Despite the loss, Lachie Schultz enjoyed his best return at goal in his new colours, with three goals from 14 disposals, while the defensive efforts of Beau McCreery (14 tackles, four clearances) were important.
