The Bulldogs are eight points outside the top eight with two games to go after giving their percentage a hefty boost by keeping the Suns goalless in the 10.12 (72) to 0.6 (6) victory at Great Barrier Reef Arena in Mackay.
Tam Hyett's charges will take on Geelong at Ballarat's Mars Stadium next Sunday then St Kilda at RSEA Park the following week and must win both games and have other results go their way to make the eight.
"We've put in a lot of effort throughout these past couple of weeks," defender Rylie Wilcox told Fox Sports.
"We've finally clicked and I'm excited to see what the next two rounds give us."
The Bulldogs leapt to 11th on the ladder (16 points, 115.4 per cent) with their third win in four games and second victory on the bounce.
Star turns from Ellie Blackburn (20 disposals and a goal), Jess Fitzgerald (22 disposals, five clearances and a goal) and Isabelle Pritchard (23 disposals, one goal) were crucial.
Young key forward Emma McDonald kicked three goals, Elaine Grigg provided a spark and defender Wilcox impressed.
Gun Suns Charlie Rowbottom (26 disposals) and Niamh McLaughlin (32 disposals) were busy, but Jamie Stanton was forced off with a left hamstring injury in the final quarter.
The Bulldogs made the perfect start when Fitzgerald threaded a terrific goal on the run from the boundary.
They added three goals in the second term to lead by 23 at halftime.
In the third term, they put the foot down.
Two minutes into the third quarter, Blackburn burst through the middle and brilliantly teed up recruit Louise Stephenson to nudge the Bulldogs out to a 29-point lead.
It set the tone for a dominant quarter where the Bulldogs slammed home five unanswered goals.
At the three-quarter time huddle, Hyett said "we cannot take our foot off the throttle" and urged her charges to remain "relentless".
McDonald kicked her third major before Pritchard put an exclamation mark on the game and her performance with a lovely goal.
Rhyce Shaw's Suns huffed and puffed but inaccuracy was costly as they ended goalless.Â
The Suns will next play Collingwood at Bond University on Sunday.
