My hamster chewed on my school tie - which I hated wearing - after I put it in a drawer I knew she liked to climb into 
I’m female btw.
My dog ate my high school yearbook, long after I might have been able to replace it. He took out a pair of not yet worn shoes too.
Darn dog!
I’ve had students who were generally honest say they had a puppy ruin their homework–I think I’ve heard “peed on” once or twice, as well as “eaten”. And I’m not even sure modern students have even heard the expression.
Yes. I had a dog eat my friend’s homework. She brought the bits leftover as proof.
No, but our dog ate an entire box of my crayons. The poop was amazing!
I’m convinced that cats have a third eye in their anuses, the way they’re always sitting on reading material.
No, but it did soil it once. Got the poop off mostly, but I still wound up redoing it rather than turn it in like that.
Dog ate my younger sister’s homework, some sort of art project thing. My parents sent the remains along with a note to explain. We all thought it was funny but my sister was not amused.
Well, not a dog, and not homework, but my African Grey, Rocco, once tore up a bunch of money I was preparing for a deposit. I stepped out of my office for literally 2 minutes and he went apeshit on the cash. The bank helped me out, but I was short $5 after all wa said and done.
I’m more careful now.
A couple of weeks ago, my husband was given some eye drops which he was supposed to use several times daily before returning to the doctor the next week. Nearly right away, they went missing…after having been left within reach of one of our counter-surfing dogs. Husband was dismayed at the thought of having to tell the doctor that the dog ate his eyedrops. 
No dog issues but I once had a cat legitimately tear up a sheet of math homework I had left on the floor.
When I was taking guitar lessons, our class used a loose-leaf book put together by our teacher. My cat Katie (of blessed memory) wested on it. Made some of the notes blurry, but after everything dried, it was still usable. When the teacher asked why the page was all crinkly with a pale stain, I lied. Said it was tea.
Most people know that Dan Quayle invented the internet as an educational tool, but few realize that WWW actually stands for “weading, wighting and withmatic”. “World wide web” is a backronym.
Our dog ate my daughter’s homework once. She didn’t think that the teacher would believe her, so my daughter took what little was left of the homework in as proof. The teacher laughed and gave her extra time to redo it.
Maybe it was a Westie. 
My dog did chew on a textbook however.
When our younger son was a high school freshman, he was assigned Thoreau’s Walden. He hated that book with a passion. The dog, who never ate a book before or since (we’ve had her for nine years; this happened 4 years ago) unzipped his backpack, took the book out, and chewed it up. We also have a picture of our son lecturing a bust of Thoreau at Walden Pond.
I thought Al Gore invented the internet.
FALSE NEWS!!!
Or brain cramp. You choose.
Does it count if a Doug ate it?
