The title "A Dog in the Manger" refers to the ancient Greek fable where a dog prevents others from eating hay while not being able to reach it himself. This expression applies to Tristan, who obstructs his cousin Leonida's marriage to his beloved Diana without intending to marry her himself. It also fits Diana, who rejects all suitors despite not loving any of them.

The title of the play "A Dog in the Manger" derives from an old proverb, which describes a scenario where a dog lies in the manger, preventing both itself and other animals from eating the hay. This expression is used to illustrate someone who, despite being unable to benefit themselves, deliberately prevents others from enjoying something good. In the context of this comedy, the title reflects the theme of selfishness and the denial of happiness to others, which permeates the narrative.

The characters in "A Dog in the Manger" who embody this expression are Diego and Teodoro. Diego, a wealthy and influential nobleman, is deeply in love with Diana, his brother's wife. Despite being unable to act on his feelings due to societal norms and moral constraints, Diego actively works to sabotage the happiness of others around him. He prevents Teodoro, who genuinely loves Diana, from pursuing her, thus acting as a "dog in the manger." Teodoro, on the other hand, is aware of his own unrequited love for Marina and yet obstructs her relationship with Fabio, again symbolizing the dog in the manger. Both characters exemplify the proverb by blocking their own and others' paths to happiness, illustrating the play’s central theme.
