The 2-1 win over Millwall at the Den saw Rovers move up to 15th in the npower Championship, five points ahead of the bottom three with just two games left to play.
Rovers responded well after going behind to an early Karleigh Osborne goal, equalising on 56 minutes after David Jones' corner kick was deflected home before Grant Hanley's 60yd run resulted in a penalty 12 minutes from time that Jordan Rhodes duly despatched.
"I thought the lads dug deep, we were well worth the three points tonight the way we went about it, the way we stood up to the fight," said Dunn after the game.
"I think that everyone in the side worked their socks and we deserved the three points.
"Out of the last four games we have won three of them so it is brilliant, I am really pleased for the team."
The Rovers stalwart felt that the midweek win banished the disappointment of Saturday's loss to Watford.
"We had won the previous two and the positive slant that Gary tried to put on it was that if you had said we had four games and you would win three of them we'd have taken that.
"So the way we have bounced back tonight was a real credit to the team and I'm really pleased for the young lads as well.
"Josh Morris, Grant Hanley, Todd Kane, they are young players starting off their careers, I'm sure they won't have too many seasons like this.
"So it is nice to see the young lads that take things on board and show a real determination to compete at a ground like this."
Rovers are back in action against Crystal Palace at Ewood Park this Saturday in the final home game of the season.
