Doberman's Bizarre Bedtime Habit Delights Internet: 'Weirdest Dogs Ever'

A Doberman's unusual nighttime routine has left dog lovers baffled online.

Everyone's bedtime routine is different—and it's the same for dogs. Some like a brief walk before settling in for the night, others are content with a dog treat or two.

However, Katana the Doberman does things a little differently.

In a clip shared to TikTok by her owner, posting under the handle celinetails, the Doberman can be seen seemingly gnawing on her own leg as the evening draws in.

According to an onscreen caption posted by her owner, Katana always does this "right before bed" and the internet is suitably confused.

Somewhere between chewing and sucking, the main purpose of her antics are unclear, however, there are some theories out there.

According to Amy Flowers, a doctor of veterinary medicine for pet care website Fetch by WebMD, such behavior can sometimes stem from allergies, dry skin, pain or parasites.

However, it can occasionally simply be a result of the canine in question experiencing a sense of boredom or anxiety.

"Just as people with anxiety might bite their nails or twirl their hair, dogs can have physical responses to psychological upset, too," Flowers said. "In fact, some dogs develop a condition akin to human obsessive-compulsive disorder. It can manifest itself in scratching, licking or chewing behaviors."

Katana's owner, Celine, told Newsweek Katana is a European Doberman who was imported from overseas to live alongside her other Dobie, Draco.

"We wanted an older dog and she was just the perfect match," Celine said.

Celine said the leg sucking is something Katana does "every now and then" but she was eager to capture it on camera.

"It's actually a form of self-soothing that is extremely common in Dobermans," she said. "Draco suckles blankets instead of his own leg!"

Celine said: "Flank sucking behavior in dogs is almost exclusive to Dobermans. It is part of a category of sucking and licking behaviors that are known as grooming stereotypes: highly repetitive, ritualized, with-function or functionless acts that animals perform periodically or continually."

She noted that no intervention is required as the sucking is harmless and causes no damage to the dog's body.

The Doberman's habit has certainly proven popular, with celinetails' video, captioned "Dobermans are the weirdest dogs ever" garnering over 6.6 million views.

Mela_Tonin55 commented, "I don't know what I was expecting but it definitely wasn't that," with NavyBee133 adding, "OK, I've seen random gnawing, but that dog appears to be literally eating itself."

Stankymeg offered up her theory on Katana's actions, writing: "She knows there's a bone in there [her leg]."

Buttons410 thought maybe the limb was serving as the dog's "emotional support knee."

The most logical explanation came from a user posting as mmmayana, who also claimed to own a Doberman who did exactly the same.

"My Dobie does the same thing," they said. "It's like their own personal pacifier."

Sarah Cassidy, another user claiming to be a Doberman owner, concurred: "My doberman just leaves her ankle in her mouth."

Celine said she hoped the video showed a different side to Dobermans.

"They are such strange dogs," she said. "They have weird quirks that I love. Everyone views them as these big, scary dogs but they're actually derps in a home setting!"
