The win moves Slough up to second place in the league behind new leaders King’s Lynn, with Kettering – the Rebels’ opponents this Saturday – slipping down to third, having been in FA Cup action.
Dobson went close on seven minutes as he saw his snap-shot from 25 yards hit the base of Martin Rice’s post, with the keeper taken by surprise.
But the Slough winger was on target with 22 minutes played, scoring a fine individual goal. After playing a one-two with Flood just inside his own half, Dobson burst forward and despite having three Tiverton defenders in close attention, took the ball into the penalty area and smashed it beyond Rice from around 15 yards.
Levi Landricombe got a free kick on target on the half hour mark, but Jack Turner was equal to it and pushed the ball aside.
Dobson again unleashed an early shot from distance which landed just wide of Rice’s post as Slough continued to carry the greater threat, and the home side were rewarded with a second goal.
Mark Nisbet’s raking 50-yard long pass forward was perfect for Dobson to run onto, and the winger was able to play a first time ball across goal into the path of Flood, whose contact wasn’t perfect but was enough to divert the ball past Rice.
Flood could have added a third before the half time whistle, but his shot was parried by Rice, with the keeper gathering at the second attempt. It would prove to be Rice’s final action as he was replaced at the interval, with an outfield player in Liam Gregory replacing him.
Slough almost started the second half with a goal, but Flood’s header from a corner came back off the crossbar.
But the second half proved to be less eventful than the first, with tired legs playing a part after Slough’s recent exploits in both the league and FA Cup.
Josh Jackman and Sean Fraser both put long-range attempts off target, whilst Flood met Dobson’s deep cross but put his effort over.
Tiverton threatened only sporadically, but a dangerous break was snuffed out superbly by Jackman, who got back to put the ball behind as Nick Hurst pulled it across.
Manny Williams almost added a third with a few minutes remaining after being played in on goal by Flood, but he was tackled and the chance was gone – however the Rebels had done more than enough overall to deserve the points.
