This is Stevie Aitken's second full season as manager.
Dumbarton finished eighth in the Scottish Championship.
Dumbarton did not advance beyond the group stage of the newly revamped League Cup, drawing 2 and losing 2 of the qualifying matches.
In the Challenge Cup, Dumbarton's abysmal record in this competition continued (5 wins from 31 starts) with a third round exit to League One opponents, Stranraer.
And it was a disastrous first hurdle exit to non-league junior side Bonnyrigg Rose in the third round of the Scottish Cup.
