Ahead of their return to the Premier League after a one-year absence, Dunne has praised the team spirit created by the players at Loftus Road since his arrival a year ago.
"You probably heard so many bad stories from a couple of years ago about how bad the dressing room was, but from the first day I came in it has been great and enjoyable," the Irish defender told reporters.
"Everyone was positive about where we were going and what the aim was, because of that people more or less looked after themselves.
"There was no need really to pull people in to tell them 'you need to be more like this'. Everyone was a good lad, they toed the line and the dressing room then looked after itself."
