Ricky Miller, Ricky Modeste and Ross Lafayette scored the goals as Dover’s impressive record against Guiseley continued on Saturday.
Whites beat the Yorkshire side for the third consecutive time in the National League to stay firmly in the play-off race with a commanding performance at Nethermoor Park.
Miller, back from his two-game suspension, opened the scoring with his 31st league goal of season to give boss Chris Kinnear’s side a half-time lead.
Modeste added the second, Miller doubled his tally from the penalty spot before a Lafayette penalty completed the rout to end Guiseley’s five-game unbeaten run.
Dover, who are seventh after the win, two points, but with two games in hand over fifth-placed Aldershot, started the game brightly.
James Hurst volleyed well wide against his former club from Joe Healy’s corner before Miller’s effort went over with home goalkeeper Jonathan Maxted out of position.
But it wasn’t long before Miller, who was also on target against the Yorkshire side in the 2-0 win at Crabble earlier in the season, did find his range.
He controlled Connor Essam’s long free-kick from inside Dover’s half before swivelling and firing past a stunned Maxted in the 15thminute.
Jake Cassidy missed a great chance to level things up four minutes later, heading Kevan Hurst’s corner wide.
Dover responded with Moses Emmanuel heading Miller’s cross over before Richard Orlu’s curling effort sailed over Maxted’s bar.
Mitch Walker made his only real save of the day just before half-time, going low to take Hurst’s shot.
Miller continued to pose a threat and ended the half with a shot fizzing just inches wide of Maxted’s goal.
Emmanuel had the first shot of the second half, seeing his effort from a tight angle hit the side netting minutes after the restart.
Hurst was next to try his luck, seeing his shot from the edge of the box curl over Maxted’s goal.
Miller went agonisingly close to doubling the lead in the 65th after his lob over Maxted hit the post and bounced clear.
But just a couple of minutes later Dover did go two-up after Modeste headed home Emmanuel’s cross from close range.
Miller stung Maxted’s hands with a thunderous free-kick as Dover went in search of a third.
It came from the penalty spot nine minutes from time after Miller was bundled over in the box and he got up to blast past Maxted.
Substitute Lafayette completed the job from the penalty spot deep into stoppage time after he had been brought down.
It was his first goal since the win at Maidstone United on New Year’s Day.
Earlier, Kinnear made two changes to his starting side with Miller and Fazakerley coming in to replace Lafayette and Sam Magri.
Magri was on international duty with Malta while Lafayette dropped to the bench.
Aswad Thomas was suspended after his red card against Bromley last Saturday while Bondz N’Gala was still unavailable due to personal reasons.
