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.

McGonagall: You don't honestly expect me to believe that a kappa ate your homework, do you?Harry: Well, it seems really silly when you put it like that. ... It didn't eat my homework, it just startled me so much I lost my homework in the lake.

- 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).

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.
