Our first win in nine attempts against the Whites, saw Wrexham finally grab three points from this season opener at the Crabble.
Mike Fondop scored the vital goal in the first half, in rather unorthodox style, but they all count.
The 312 travelling fans lapped it up and enjoyed their day out within sight of France.
There was no Chris Holroyd or Nicky Deverdics through injury, but debuts for Luke Summerfield, Luke Young, Mike Fondop and Stuart Beavon in the starting line-up.
First real attack of the game came from Wrexham on 10 minutes, as Paul Rutherford's inviting cross from the right was headed behind for a corner by the giant figure of Swiss defender Tim Scholl.
The home side responded two minutes later, when Jamie Allen's effort from 20-yards crashed off the Rob Lainton's cross bar.
On 20 minutes, Fondop killed a high pass 40 yards out and strode towards the home goal, but after such a lovely piece of skill his shot at goal lacked the power to worry Mitch Walker between the Dover posts.
Some great football from the Dragons midway through the half, saw Fondop knock a long clearance down for Rutherford's cross field ball to Luke Summerfield on the right, he cut inside along the penalty box, before setting up Luke Young for a shot that passed just the wrong side of the left hand upright.
Then on 29 minutes, the Welshmen took the lead following a half-cleared corner when Summerfield played the ball in again towards Mike Fondop who, with his back to goal and falling backwards, managed to hook his effort goalwards and into the corner of the net with Walker flat footed.
Into added time at the end of the half and the referee awarded a penalty against Wrexham, as Akil Wright was judged to have fouled striker Inih Effiong. The Dover man leapt to his feet, picked up the ball and headed to the mark.
As the kick was taken, Rob Lainton dived full length to his right and was able to push the effort away for a corner, much to the delight of the large travelling support behind his goal.
The Reds then survived the following corner and were happy to hear the whistle for half time, despite having played well in the opening 45 minutes.
In the first minute of the second half, the Wrexham failed to clear the ball and Josh Passley's low cross from the right flew across the face of the goal without anyone close enough to add the finishing touch.
Stuart Beavon was looking at the referee for a foul on the edge of the Dover's area after 49 minutes, when he appeared to have had his ankles tapped from behind, not that the match official was having any of it.
There was a yellow for Schmoll on 55 minutes, when he then caught Beavon, 20-yards into the Dover half, as the Wrexham man threatened to break through the Athletic back line.
Summerfield's free kick bounced passed all the outfield players crowded in the home penalty area and almost caught Walker unawares, as the keeper scrambled across to touch the ball away for a corner.
A few moments later and Beavon was replaced by Jordan Maguire-Drew, who only received his International Clearance late on Friday afternoon, following his midweek move from Premier League side Brighton & Hove Albion.
Former Barrow man Bedsante Gomis made way for Kadell Daniel on 74 minutes, after finally getting booked, with referee Rock having spoken to him on three occasions before eventually going to his top pocket.
Fondop won a corner on 80 minutes, with Summerfield delivering it long and Shaun Pearson getting firm contact on the ball with his header, but in the ensuing scrum on the goal line it was finally knocked clear.
Immediately afterwards, Fondop was replaced by Rekeil Pyke, as the big man looked to have run himself into the ground on a swelteringly hot afternoon.
With eight minutes left, Rutherford made way for Mark Carrington as another pair of fresh legs entered the fray.
Dover did have the ball in the net on 88 minutes, but the whistle had gone for a foul on Lainton as he jumped for a high ball - maybe a little fortunate, but we were happy to take it.
Into added time, the Reds had to clear their lines on several occasions, with another tall figure in the shape of centre half Moussa Diarra, sent on to see if he could salvage something at the death.
The last few moments played out and the final whistle was met with great applause from those in red and white.
Next up for the Dragons will be AFC Fylde at the Racecourse on Tuesday night (7.45pm).
