The unique union came into the public consciousness after a picture of the two canines was posted to Reddit by the user pardon_01.

In the picture, what looks like a Yorkshire Terrier can be seen lying sprawled out on a tiled floor, close to what appears to be a German shepherd.

What makes this particular image unique, however, is the way in which the two dogs’ tails perfectly overlap one another, giving the canines the appearance of being conjoined. The image can be viewed here.

In an age when cute dog pictures are ten-a-penny on social media, this particular effort offered something different and an opportunity for dog fans to let their imaginations run wild.

Like a canine coming in for a drink of water after a long walk in the sun, they lapped it up, with the post earning close to 14,000 upvotes and quips aplenty from dog lovers everywhere.

“First we had CatDog, now I give you, DogDog,” OliverKlozoff1269 joked.

“Does the little dog have a big dog tail or does the big dog have a little dog tail?” Cannibalism_is_vegan asked.

EastVanWillieD was overjoyed, declaring: “Twice the dog and thrice the cuteness,” while dfvisnoacat declared the dog a “tailshire terrier.”

“Tail wagging the dog,” mikebrown33 quipped in reference to the old saying for when an individual is being controlled by something less powerful.

In this instance, the terrier was imagined as the more dominant of the two canines.

All joking aside, however, arguably the best and truest comment came from toooldforlove, who declared the image the “cutest confusing perspective” they had ever seen.

Newsweek has contacted pardon_01 for comment.

Though it may be fluffy (in every sense of the word) science has shown that animal-led contact can have a beneficial impact on humans.

Rebecca A. Johnson, Ph.D, director of the Research Center for Human Animal Interaction at University of Missouri, highlighted the benefits in an interview with NBC News.

She explained that “when we see, touch, hear or talk to our companion animals,” beneficial neurohormones “are released and that induces a sense of goodwill, joy, nurturing and happiness.”

Johnson said the stress hormone cortisol is also suppressed while blood pressure, heart rate and respiratory rate can all decrease, meaning we are able to “manage stress in ways that aren’t harmful to our health.”

Research conducted by Caltech also highlighted how individual brain cells respond when seeing an animal but not when seeing a person, place or object.

Some 41 participants were shown a variety of photos while researchers analyzed activity in the amygdala, the part of the brain responsible for alerting us to things of emotional interest.

They found that photos of animals elicited the greatest response.

This isn’t the first time an optical illusion involving a pet has gone viral. One cat, who appeared to have been skewered by a whisk was recently racking up millions of views on TikTok.

In other adorable yet bizarre dog news, one canine was left with a lot of explaining to do after CCTV caught him driving a golf cart into the side of his owner’s car.
