Spurs were unlucky not to get a spot-kick when Stiliyan Petrov tripped Jermain Defoe in the box.
Dunne told ESPN: “It looked like a penalty, but we got a good decision and we’re happy.
“It was very difficult. Tottenham are a very good side and the same as ourselves are pushing for the top four.
“Our main objective was to come here and take some points so we’re quite pleased.
“We had a blip over Christmas so to get back in the points is important.”
