Both anime has an Absurd element.
In dog days, the 'war' in the story is less than you expect with the hero defeating enemies while learning the rules of the battlefield.
In ben-to, the premise is fighting for half-priced bento and taking it seriously. This is a good anime, so don't judge an anime by it's premise.
