David Leworthy gave Athletic the lead in the 37th minute of a lack-lustre first half.
But two goals in three minutes after the break by strike partners Ansil Bushay and West followed by another from West in the 65th minute brought the game to life and retained Slough a share of top spot.
Sub Paul Carruthers hit a spectacular bicycle kick second for Dover in the 87th minute, but the result at that stage was academic.
With 39 goals scored in eight Conference games, the Rebels are revelling in their all-action reputation. The dozen this week, however, included five more against and Slough are well aware of the need to tighten up in at the back.
Leworthy's goal saw the defence flat-footed when trying to catch one of the league's top forwards in the off-side trap. Trevor Bunting, making his first appearance of the season in goal, stood no chance.
Dover, despite propping up the bottom of the league, showed flashes of promise, particularly up front where Jermaine Darlington, whose cross Leworthy converted, and Corey Browne caused problems.
The only real threats from Slough came from full back Andy Clement who brought out a good save from Efrem Ebbli in the 23rd minute and pulled a shot wide from the edge of the box three minutes later and Bushay who dragged the ball wide in the 30th minute.
Slough, though the spark would not ignite, were always on top with Mark Pye commanding in midfield.
But Bushay changed all that a minute into the second half, his flick for goal as he drove in from the right edge of the box helped on its way by John Budden.
Three minutes later West had the Rebels ahead, Mark Fiore making the all-important cross from the left after Bushay had retrieved the ball in the corner and laid it back.
Fiore's first time touch was met by West running in to the near post and a deft touch with the head went in off the far upright.
Bunting made one crucial save in the 64th minute after Leworthy and Browne combined to release Darlington, but the Dover man found Bunting's reactions in the final showdown too quick.
A minute later Fiore, who looked unhappy after being moved to left back when Neil Catlin limped off, played in a free kick from the right which Bushay helped on for West to score his seventh goal of the campaign.
Athletic launched a late assault in an effort to change their luck and Carruthers' sharpness was rewarded after Slough had only partially cleared a free kick.
Slough's choral section behind the Dover goal once again went home with sore throats and stinging hands as they rapped out their appreciation for another rousing performance.
