(CNN) - Ratting out a dog for bad behavior is becoming a popular trend.

Humans aren't so appealing when they get shamed for bad behavior, but when a dog confesses "I hid meat in the couch" there's no hiding the cute factor.

On the Tumblr page "Dog Shaming," doggie sins ranging from sex "I hump every stuffed toy I find," to gluttony are celebrated. The grosser, the cuter.

Owners pose their pets behind shaming signs, often with evidence included in the photo.

Sometimes they send a tag team of transgressors: "I puked in our crate and I ate it," said one.

"I pooped by the elliptical machine. I ate a Herman Melville novel," said another.

There are even murder confessions, such as "We killed a mockingbird."

Dog owners and dog walkers in Central Park had their share of shame-worthy stories.

Take Kona. He has a habit of jumping into dirty fountains.

"I took him to the Hudson River last week and he started swimming to Jersey," said Kona's owner. She had to practically drag Kona out.

Barking is a popular dog shaming topic.

"I bark at doorbells on TV, but we've never had a doorbell," read one sign.

But underwear eating seems to be one of the most common misbehaviors.

"I am an underwear eating jerk," accompanied by the chewed-up boxer briefs to prove it.

It's not eating, but drinking that gets Daphne and Augustus into trouble at the toilet.

"She uses her nose. She pries the seat up, she lifts it he comes right behind and they start drinking from the toilet bowl," said their owner.

As with humans, sex leads many dogs astray.

"I humped a blind cocker spaniel's face" read a sign.
