The R's continued their unbeaten start to the new season thanks to a narrow 1-0 victory at the Reebok Stadium.
"The way the season is shaping up already, it's clear that you need to make a positive start and we've certainly done that," Dunne told the club's official website.
"It might not have made for the prettiest of games at times, but we'll take any kind of victory on our travels.
"We're fighting harder than anyone at the moment and we're getting the reward for our efforts."
QPR continue their bid for promotion on Saturday when they travel to Leeds United.
