Hello, curious creatures! Yuna here, reporting live from my favorite tactical observation post: the very top of the living room bookshelf. From up here, I can see everything. I see the dust motes dancing in the sun. I see the red laser dot that I will definitely catch one day. And, most importantly, I see the utterly baffling behavior of my canine housemates and our humans.
The other afternoon, our favorite human was sitting on the couch, typing away. Suddenly, they let out a massive, jaw-stretching yawn. Moments later, right on cue, Blu—our lovely, high-energy Griffon Bleu de Gascogne—looked up from his chew toy, opened his mouth, and let out a squeaky, dramatic yawn of his own. It was like a synchronized dance, but with sleepy noises.
As a cat, my first instinct was to knock a pen off the desk to break the spell. But my second instinct was curiosity. Why on earth do dogs copy our yawns? Is it mind control? A secret canine language? Or are they just really, really tired? I decided to dig into the scientific literature (and walk across a few keyboards) to find the truth. Here is what I discovered about the cozy, chaotic world of contagious yawning.
The Shocking Truth: Yawns Really Are Contagious
As it turns out, catching a yawn is a real biological phenomenon, and dogs are one of the few non-human animals who do it. For a long time, scientists thought this copycat yawning was a uniquely primate trait. But researchers decided to see if our canine companions were in on the secret.
A groundbreaking study published on PubMed Central (PMC) and detailed in ResearchGate demonstrated that dogs actually “catch” yawns from humans. In the study, a whopping 72% of the dogs yawned after watching a human yawn. When the human just opened their mouth without yawning, the dogs did nothing. This proved that dogs aren’t just copying mouth movements; they are specifically responding to the actual act of yawning!
Is It Love, or Just Copycatting?
Now, as a cat, I pride myself on being independent. If a human yawns, I simply stare at them with slow-blinking superiority. But dogs are famously social, pack-oriented creatures. This brings us to the big question: why do they do it? Is it driven by empathy?
The answer seems to be a heartwarming “yes.” According to research shared by the Greater Good Science Center at Berkeley, contagious yawning in dogs is closely linked to empathy. It is a way for dogs to emotionally connect with the humans around them. When you yawn, your dog’s brain registers your state, and their automatic mimicry is a sign of social bonding.
To make things even sweeter, dogs prefer catching yawns from people they actually know. A study published on PLOS ONE and highlighted by the University of Tokyo monitored dogs’ heart rates while they watched both familiar humans (their owners) and complete strangers yawn.
The results were fascinating: dogs yawned significantly more often in response to their owners’ yawns than to a stranger’s yawn. Furthermore, their heart rates remained stable, meaning the yawning wasn’t caused by stress or anxiety, but rather by a deep, empathetic connection to their favorite human. It’s basically their way of saying, “I hear you, human. We are tired together.”
When a Yawn Means Something Else entirely
Before you run off to yawn at your dog to test this, we need to cover an important safety and behavioral tip. As the experts at the American Kennel Club (AKC) point out, dogs also yawn for reasons that have nothing to do with sleepiness or empathy.
In the canine world, a yawn can be a “calming signal.” When a dog is feeling anxious, stressed, or overwhelmed, they might let out a big yawn to try and soothe themselves or defuse a tense situation. This is often accompanied by other body language cues, such as:
- Licking their lips
- Avoiding eye contact
- Tucking their tail
- Tense body posture
If you notice your dog yawning in a busy, loud, or unfamiliar environment, they probably aren’t trying to bond with you—they might just need a little space and a quiet place to relax. According to studies on canine behavior, including research on PubMed, distinguishing between a stress yawn and an empathetic copycat yawn is key to understanding your dog’s emotional state.

The Cat’s Verdict on Canine Copycats
So, what have we learned today from my high-altitude scientific investigation?
Dogs are incredibly sensitive, emotionally intelligent creatures. Their brains are finely tuned to our expressions, our moods, and even our sleepy sighs. When Blu copies our human’s yawn, he isn’t just being a silly goofball (though he is definitely that, too). He is demonstrating a profound evolutionary bond that humans and dogs have shared for thousands of years.
Personally, I think it is a bit showy. If I want to show my human affection, I simply walk across their face at 3:00 AM or present them with a very nice, crinkly plastic wrapper. But I suppose catching yawns is a cute trick, too.
Next time your pup copies your yawn, give them a gentle pat on the head. They are telling you they love you, one giant, sleepy gasp at a time. Now, if you’ll excuse me, all this talk of yawning has made me incredibly sleepy. It’s time for my third nap of the afternoon. Stay curious, friends!
