BVB stormed to a resounding victory over the Bundesliga basement club with a brilliant first-half performance, which included five goals, keeping them on target to finish second
In front of Jose Mourinho, scouting ahead of his Real Madrid side's meeting with BVB in the Champions League, the visitors were indomitable. Mario Gotze opened the scoring after just 12 minutes and Ilkay Gundogan and Jakub 'Kuba' Blaszczykowski added goals before the half-hour mark.
Gundogan and Gotze both then doubled their respective tallies for the afternoon before Edgar Prib managed to net a consolation goal for the hosts. Robert Lewandowski then finally got in on the act, wrapping up the scoring with his side's sixth.
The Cloverleaves have not managed to win at home this season and it was clear they were going to have a tough time trying to correct that with Wolfgang Hesl called into action after just 10 minutes.
It only took BVB two more minutes to find the net as Sebastian Kehl passed the ball out wide to Gotze, who then shimmied inside Jozsef Varga and drilled a shot past the keeper and in at the near post.
Three minutes later, Dortmund doubled their advantage as Kuba rushed across the face of the defence and drove a low cross to Gundogan who was on hand to convert with a simple tap-in.
Furth were powerless to resist the fluid attack of BVB and after seeing a close-range effort go wide on the rebound from Lewandowski's shot which had hit the bar, Gotze recovered by supplying the cross for Kuba to dive and head the ball into an empty net.
Kuba turned provider again in the 34th minute as he surged down the right and showed great vision to cut the ball back for Gundogan who guided a brilliant effort into the bottom corner.
Makeshift left-back Kevin Grosskreutz almost got in on the act before the break and although his shot was saved, there was still to be a fifth. Gotze superbly glided along the top of the box from the left and with the defence offering him space to move into he rifled the ball into the back of the net.
Following Gotze's half-time withdrawal, Furth were allowed to have a lot more of the ball after the restart but for much of the game they struggled to string together a meaningful attack.
That was, however, until the 71st minute when Prib combined with Thomas Pledl to break into the area from the left. He kept off the challenge of Lukasz Piszczek and poked the ball past Weidenfeller and inside the far post.
There was still time for one more from the rampant visitors as Lewandowski, refusing to be denied a goal, raced in to slide home from Kuba's pass across the face of goal 10 minutes from time.
Jurgen Klopp's men subsequently open up a temporary gap of nine points over third-placed Bayer Leverkusen, while Greuther Furth move closer to the drop, 11 points adrift of a relegation play-off position.
