The Warriors have lost three of seven fixtures on the road so far. Last season, they lost five in total and the year before that, seven.
"We've developed our game away from home a lot this season," Dobie told the BBC Scotland Sport website. "There were points in the last few years when we struggled to get many results away from home.
"If we do need to travel for any play-off matches, we can still be confident with our game. The aim is to finish at the top and to have the potential of a home run-in, if we can stay performing well and winning those play-off matches as well."
Glasgow last win in South Africa was against the Cheetahs in Bloemfontein in 2018 - but Dobie insists his side are not thinking about that.
"It's definitely doable," the scrum-half said. "We've seen teams go out there and perform. Munster have gone and got two wins on their trip and they've obviously had a lot of success out there.
"The past and our previous results aren't influencing much about how we feel about this trip. We know how important the matches are and how big getting wins out there would be for us. If you're looking too much at the past results, it could play in your head a bit, but that's not in our mindset at all."
