Both teams had managed just a solitary victory during the competition beforehand, and occupied the bottom two positions.
However, flyhalf Christian Rust produced a standout performance as his 21 points steered the Boland outfit to a comfortable bonus-point victory, sealing a respectable sixth-place finish in the process.
For the Bulldogs, it was a disappointing end to a campaign in which they regularly summoned gutsy performances, and they were simply outplayed by a clearly superior side.
Rust opened the scoring in the seventh minute with a calmly taken penalty, before crashing over the whitewash himself six minutes later. He made no mistake with the conversion, and inside-centre Albert Trytsman's try in the 19th minute saw the home side race out to a commanding 17-0 lead.
The Bulldogs were able to muster a response, and some good build-up play was rewarded with a try in the 30th minute by tighthead Johannes Jonker to reduce the deficit to 10. But flanker Franzel September struck a crucial blow shortly before half time, as he dotted down to take the wind out of the Border sails by the break.
To their credit, the visitors once again showed courage, and winger Lola Waka demonstrated his pace with a fine score shortly after play resumed, and with the deficit at eight points, Border were still in the contest.
But the hosts simply clicked into gear, and tries from Arno Fortuin and Clemen Lewis put the game well beyond Border, before Rust rounded things off neatly with a second converted try five minutes from time.
