Fremantle lost their clash with the Western Bulldogs by 49 points at Optus Stadium on Friday night.
Fremantle's focus on Rory Lobb, who left in messy circumstances at the end of last season, was clear before the opening bounce when captain Alex Pearce ran straight through the tall forward, sparking a scuffle.
And it was clear during the third quarter when a handful of players wrestled with the new Bulldog and allowed Adam Treloar to pounce on a mis-kicked set shot and snap a crucial goal.
When they needed to respond in the final term they couldn't, conceding five goals to one as the impressive Bulldogs prevailed 17.16 (118) to 10.9 (69) with an important win that squares their season at 3-3.
Fremantle, meanwhile, are back to square one after ball-movement issues and poor connection with their forwards became issues again and their season reached a flashpoint at 2-4.
Bulldogs captain Marcus Bontempelli was brilliant throughout but lifted when the game was alive, finishing with 31 disposals (18 contested), eight clearances and two goals.
Sidekick Treloar challenged for best afield honours with his two superb goals at crucial times, finishing with a team-high 35 disposals and three score assists as the Bulldogs dominated contested ball 154-129.
They had winners all over the ground and a depth of contributors, with Bailey Williams kicking a career-best three goals, Jamarra Ugle-Hagan taking a career-best 10 marks, and Jack Macrae winning a career-best 14 clearances.
As a team, they were able to lock the ball in their half for long periods and build pressure, linking up with well with handballs and winning the inside 50s 60-45 in their second straight game on the road.
Fremantle has been plagued by slow starts this season and Friday night was no exception, with the Bulldogs dominating field position early with 10 of the first 12 forward entries.
The issue for the Dogs was their conversion, kicking 0.6 to start the game while Freo converted from each of their first two forward entries and making up for their stilted ball movement with efficiency.
The Bulldogs eventually started capitalising, with Bontempelli asserting himself through the midfield and entering quarter time with nine disposals and a goal as the Bulldogs built a seven-point lead.
They took their momentum into the second term and when Aaron Naughton, who finished with three goals, caught Ethan Hughes holding the ball and converted his free kick, the Bulldogs had kicked six of the last seven goals to open a 25-point lead.
The Bulldogs had no right to get comfortable after last year's elimination final loss, however, and Fremantle again mounted a comeback, launching their own run when in-form small forward Lachie Schultz converted on the run.
Clever half-forward Sam Sturt then showed why he is in this team, kicking back-to-back goals after finding space inside 50 and cutting the margin to just six points.
The Bulldogs needed to steady after cracking under Freo's increased pressure around the ball, and the man who got them back on top was Lobb.
The former Freo Docker marked inside 50 and, to a chorus of fierce boos from the crowd, converted his set shot from just inside 40m to lift the Bulldogs.
From there, the Bulldogs got their hands dirty and prevented Fremantle from getting any momentum when they threatened in the third quarter and three times cut the margin to 18 points.
They would get no closer though as the Bulldogs recorded one of their gutsier road wins.
