The Royals are now seven points adrift of safety and without a manager, following Brian McDermott's dismissal at the beginning of the week.
"No-one was more surprised than me," said Dolan.
"It is well documented that Brian is a good friend of mine but the decision was made and we move forward."
Reading did not create many chances. But they still left lamenting referee Lee Mason's refusal to award a spot-kick for Nemanja Vidic's clear push on Adrian Mariappa inside the area at the start of the second half.
"It was a clear penalty but I think the referee thought I was on work experience and 'perfect a little 1-0 loss for Reading' and would be fine," he said.
"I wouldn't have expected that from the referee but what can you do?"
