The former Plains Farm Amateur Boxing Club national and Commonwealth Games champion has fought at heavyweight since joining the professional ranks almost three years ago.
He said: "The weight I boxed at for most of my amateur career was heavyweight, but that's closer to cruiserweight in the pros.
"Going cruiser has always been on the agenda and I've been relaxed about what weight I go in at.
"I had to gain weight after turning pro, but that's coming off without too much problem."
The only blemish on Dolan's professional record was his loss to Belfast's Martin Rogan in the final of Sky TV's Prizefighter show in April.
That was his last contest, but that defeat had no influence on the decision he's made in conjunction with Hartlepool-based coach Neil Fannan.
"Neil thinks it's the wisest thing to do and we're going for it," said the 28-year-old. "I feel I've progressed a lot with Neil and I've got total trust in him.
"I'll go from being one of a smaller, agile heavyweights to one of the bigger cruiserweights, which could have its advantages.
"I've got to the point where I don't think I'm too far off a title shot and that is one of the reasons Neil mentioned cruiserweight because he feels there might be some more opportunities there.
"I'd like to fight for a title by the end of the year, or perhaps early next year."
Coach Fannan is backing Dolan to go all the way to a British Championship triumph – and beyond.
Dolan's first cruiserweight outing will be on a televised show in Liverpool on Friday, July 4.
"We are going to dip our toes into the cruiserweight division," explained Fannan.
"When Dave fought in the Prizefighter, he we was 15stone 6lbs when he went on the scales – and he had his jeans on.
"And by the time he got through to the final, he was probably no more than 15 stone.
"That was a time when I encouraged him to keep weight on, so I'm very confident he'll make the 14stone 10lbs at Everton Park Sports Centre on July 4.
"If he comes through that fight successfully then we'll be looking to push on.
"I know I don't like looking further than the fight in front of us, but I do have high hopes that Dave will not only win the British title but go beyond that."
Dolan rattled off nine straight wins at the start of his pro career and reached the final of the exciting Prizefighter heavyweight tournament in London.
He came unstuck in the final against Rogan, but he certainly enhanced his reputation thanks to his boxing ability.
Fannan says they are not admitting defeat as a heavyweight – merely exploring a new avenue.
There were no problems with Dolan's boxing skills – he was faster and more mobile than the majority of the fighters on the heavyweight scene.
But the 2002 Commonwealth Games super-heavyweight champion lacked one vital attribute at the weight – sheer size. He was several inches shorter and stones lighter than the top men in the division.
"He could outbox any of them," said Fannan. "But if plan A wasn't working I couldn't say 'go in a wrestle him a bit, rough him up'.
"At cruiserweight, he will still have the speed, the boxing and the power.
"He hits hard enough as a heavyweight and he'll be able to carry that into the cruisers."
Fannan added that it was all systems go for his contest at Everton Park Sports Centre, although no opponent has been finalised.
"He'll make the weight no problem," said the coach. "He only has six pounds to lose and he's not been on a diet.
"We went to see Ian Campbell at Title and he sorted us out with something called Feed and Lean, a food replacement drink.
"It's what we did with Michael Hunter and it worked.
"But so far David has not needed it, the weight is coming off thanks to his training and sensible eating."
The British cruiserweight title is currently vacant, with Londoner Michael Steeds and Rob Norton of Stourbridge due to contest it in early September.
