Dumbarton played league football in Division 1 for the third year running. Davie Wilson's first season as manager began well, and while always up with the leading pack, it was to be the case that too many draws rather than wins would prevent a serious challenge on the title. Nevertheless, a 4th-place finish was a creditable result.
In the Scottish Cup, Hearts were once again the opponents, but it was Dumbarton who were to progress this time after a drawn game. In the quarter-final, however Partick Thistle were to prove too good on the day.
In the League Cup, qualifying groups were dispensed with and replaced with straight knock-out ties on a home-and-away basis. It was however to prove a bit of an embarrassment when in the first round, a 4–1 home win against Hamilton was followed by a 6–0 away drubbing.
Locally, in the Stirlingshire Cup, Dumbarton were defeated by local rivals Clydebank in the semi-final.
