A New Study Debunks the Theory That “Puppy Dog Eyes” Are for Humans’ Benefit

Apparently wild dogs can be pretty cute, too.

My dog, Finn, is not the sharpest tool in the shed. He’ll come when called — mostly. When told to “sit” and “stay,” he’ll sort of loiter. And the months I’ve spent trying to teach him basic tricks have brought nothing but humiliation to us both. But, no matter what, I always say “Good dog, Finn!” I have to. It’s the desperate look in his eyes. This facial expression speaks volumes. It says that he loves me, he hates to disappoint, and he’d give anything to make things right.

It’s a wildly winsome, beseeching look that would be too on-the-nose for an animated bunny in a kids movie. It’s a look that self-captions as, “Awww,” or “Who, me? ” The expression is so lethally, infamously cute that a Danish pop star wrote a song about it. I saw it on Finn the other night, right after he woke up the entire household at 2 a.m. with loud, alarming barks because a neighbor deposited a little recycling.

That deeply manipulative, adorably effective little smirk Finn fixed me with is what researchers have deemed “puppy-dog eyes.” But new research published in the journal  The Anatomical Record shows dispels a 2019 study that dogs got this adorable look as a result of domestication by humans. This new study finds that it is also present in wild dogs.

They didn’t evolve just for us, after all.

The 2019 study reported that an eye muscle, entirely absent in wolves, enables subtle facial movements that “increase paedomorphism.” Anne M. Burrows, as one of the study’s authors, told Australia’s ABC News that this is a buzzkill way of saying that dogs “hijack our emotions.”

In other words, the study found that dogs have evolved over time to mimic our facial expressions and, as a result, create a very human-like, beseeching look that allows them to get exactly what they want from us. But just because that muscle wasn’t present in wolves, does it mean only domesticated dogs have the puppy-eye dog capability?

Heather Smith, a researcher at Midwestern University and her team wanted to dig deeper. When they studied a deceased African wild dog (Lycaon pictus), they found that the puppy-dog eye muscles were just as developed in that dog as they were in dogs who live with humans.

“So, it kind of debunks the idea that domestic dogs are the only canids that have this, and that they evolved specifically for us,” Smith told LiveScience.

Pups and their people share a “mutual gaze.”

Even if this charming attribute of dogs’ eyes is not the result of humans’ influence, it has contributed to our bond with our pups. In a statement about the 2019 study, Burrows, senior author, says that these tiny facial muscles, which flex and tire just as quickly, create a “mutual gaze” between humans and dogs that doesn’t happen between us and other pets.

It’s safe to say that when we see our dogs looking at us like we used to gaze at our parents when we wanted that extra bowl of ice cream, we can relate to them. Regardless of how they originally developed those pleading eyes, they do manipulate us. Finn is living proof of that — quickly disarming my frustration with just one look.

It’s not like we can complain: We love to give them exactly what they want. And apparently, if we come across any wild African dogs, we might similarly influenced by them and want to fulfill their every desire. Guessing they might not be as satiated by pet store-bought treats, though.
