This is the second episode where Donald tries to find a way to cure his temper; the first one was Self Control. However, this one differs from Self Control in that Donald has better luck learning to control his temper (he returns to his old angry self at the end of the Self Control). His curing in Cured Duck seems to be more successful; Donald does not have any extreme temper outbursts in cartoons following this one (though he still seems to be easily agitated).
The ending of this cartoon evidently proves that Daisy herself has a temper even worse than Donald's, hence this makes Donald not the only Duck that needs anger management training.
This is the final cartoon where Donald's usual blue sailor shirt has four white buttons on it; beginning with Donald's Double Trouble the white buttons have been removed from his sailor shirt.
