It’s actually scientifically proven that dogs and their owners look similar. One 2004 study published in the journal Psychological Science found that people were able to match photos of dogs and their owners, based solely on physical similarities.

And a 2015 study published in the journal Anthrozoös revealed that it’s similar eyes in particular that give the pairings away. Now, whether or not people seek out pups who look like them on purpose is still up for debate. But one thing is clear: Dogs who look like their owners is a common sight.

And we have the proof. Check out these identical canine-human duos and prepare to be amazed!

These long faces

This basset hound and its owner were captured by Reddit user Alice Thompson walking through Boston. Not only do their brown, white, and black looks match, but their long faces and the way they carry themselves are similar too.

This sleek set

This dog’s perfect blonde hair could be anyone’s photo inspiration for their next trip to the salon. And seemingly, his owner couldn’t agree more. The U.K.’s Channel 4 shared this photo on Twitter to announce their dog and owner look-alike contest. We think they found their winner.

These curly cuties

Juliette Woolf entered herself and her pup, Rosso the cockapoo, into the U.K. contest on Twitter. It’s not hard to see why!

These perfect pouts

When this pug struck a wide-eyed frowning pose, its owner hilariously matched the pup’s look. It’s no wonder they got tons of likes on Twitter.

These piercing pals

When Liam Rice posted about his husky, Luna, on Twitter, people couldn’t get enough of their hilarious photo series. In each picture, the pair proves just how in sync they are—from their stunning blue-grey eyes to the model-like expressions on their faces.

These striking smiles

This owner and her dog, who were posted on Reddit by Reddible, certainly aren’t afraid to smile with their teeth (quite a bit of teeth, to be honest).

Two-toned twosome

Heterochromia iridium (AKA having two different color eyes) is very rare. So it’s truly mind-boggling that in this photo (which user @AnthonyNapkins shared on Imgur), this woman and her dog both each have one brown eye and one blue eye… and on the same sides!

This wispy duo

This scruffy pair is definitely related. Dog owner Duncan shared on Twitter that as his hair grew out, he started to resemble his dog.

These graceful agers

Based on this tweet, Judith and her dog Jimmie have enjoyed a long life of fun together—and they have the matching curly gray hair to prove it.

These hazel-eyed hunks

Social media star Topher Brody has made a living off of just how much he and his similarly-colored Ausiedoodle, Rosenberg, look alike. This is one of their earlier pictures, but there are tons more on Brody’s Instagram.

These strawberry blonde beauts

Caroline wasn’t afraid to admit on Twitter that she rocks the same locks as her dog Joey.

These mop tops

It looks like these human-canine pals spent a summer day sweating it out at a water park, based on their matching damp hairstyles and relaxed dispositions.

These sleeping beauties

Twitter user @JAMSXD shared photos of herself and her dog wearing matching outfits and sporting the same expressions as they settled down for a nap together. They are quite the pair!

These blue jean babies

What’s cooler than being cool? Having matching ice cold blue eyes with your dog, of course!

On Imgur, user @cakewar shared a series of adorable photos of her and her rescue pitbull named The Stig. In her post, she wrote, “I didn’t realize it until I started getting comments from friends and on the street about how much our eyes match.” She added that she and The Stig are “soul mates.” Aww!

These big grins

It often seems like, no matter how hard you try, you can never get your dog to sit still for a photo. But this owner’s post on Imgur is proof that the perfect side-by-side puppy selfie is possible.
