Basically, this is any child character explaining to his teacher why he hasn't done his homework. This will be either a lie, which may or may not be believed, or a Cassandra Truth. If it is the latter, expect them to also bring in the evidence proving their case (such as moist bits from homework, or even the animal itself.) The most common variant involves a dog, but other animals can be used as well.

Though this has become a Dead Horse Trope, and children rarely use this excuse seriously, the second variation on this trope is in fact Truth in Television. Many dogs do have a thing for paper, or are just Extreme Omnivores.

Examples of A Dog Ate My Homework include:

Anime and Manga

  • In Futakoi, Nozomu is always wary whenever the goat is around when he's doing his homework. No one believes Nozomu because the little bastard is nice to everyone except him.

Comic Books

  • A Disney Adventures Goof Troop comic had PJ offering this excuse for his homework. Though he had the sense to bring Chainsaw, still attached to said homework, with him.



  • Aliens Ate My Homework (they really did, too). It doesn't end well, but the aliens appreciate how the apparent Refuge in Audacity helped cover for the other weird things that were happening.
  • Discworld:
    • Mentioned in Thief of Time, in that no dog dares to eat homework given to Susan's students. Instead, they sniff it out and carefully bring it to her class if the kid forgot. She is like that.
    • In another Discworld book it's mentioned that at Unseen University, your homework could eat the dog.
  • A Peanuts picture book has a literal version. Snoopy was playing WW 1 Flying Ace and pretended Sally's book report was sensitive papers. She chased him and he swallowed the report. So she takes him to school the next day and takes him up in front of the class.

 Sally: I might have a little trouble reading it. *shakes Snoopy* I SAID...I might have a little trouble reading it!


Live Action TV

  • In one season 10 episode of M*A*S*H, Hawkeye gets in serious trouble because a goat ate the entire payroll (and, naturally, no one believes him; he is charged with stealing it). Later, Hawkeye is finally proven innocent when the goat subsequently eats a general's report on the issue. Seems sort of the same thing in spirit.
  • Briefly mentioned in an episode of Wizards of Waverly Place when the Russos adopt a dragon that's been transformed into a beagle. At one point, the dragon dog sets Alex's homework on fire, to which she comments: "The dog burned my homework, that's a new one."

  • An episode of Ned's Declassified School Survival Guide involved Ned giving tips on good excuses. He comments that saying a dog ate your homework is a bad excuse... right before a dog eats his homework. The rest of the episode has him trying to find the dog and convince his teacher Mr. Sweeney that he wasn't lying.
  • Married... with Children invoked this trope in an episode where Peggy goes Back to School because she didn't pass home economics (no surprises there). At a scene, a teacher asks the class to wake Kelly, who quickly responded that her dog at her homework. Later on, when Peggy is introduced to class, both her and Kelly fall asleep and the teacher asks the class to wake them both, who responded that the dog ate their homework.
  • In one episode of Tattooed Teenage Alien Fighters From Beverly Hills, one of the heroes was doing her homework when they've been called into battle. She then took the homework with her, eventually leading to the homework being eaten by the monster. The teacher later sarcastically asked if a dog ate her homework. She answered it was a monster and the teacher took it for sarcasm.
  • Superhuman Samurai Syber-Squad had an episode titled "A Virus Ate My Homework". Unlike what the title might have made fans expect, Sam's homework wasn't eaten. His little sister painted it over.

  • Invoked in the lyrics to the theme song for Saved by the Bell.
