If you’ve ever watched your dog’s paws twitch while they sleep, seen their tail wag against the couch cushion, or heard a soft bark in the middle of the night, you’ve probably wondered what was happening in their little world. Were they chasing a ball? Running through a field? Or maybe, just maybe, dreaming about you?
According to new research, that last guess might be closer to the truth than we realized. Scientists studying canine sleep patterns now believe that dogs don’t just dream—they often dream about the people they love most: their owners.
Harvard psychologist Dr. Deirdre Barrett, a clinical and evolutionary expert on sleep, has been studying the science of dreams for decades. She explains that dogs, like humans, experience Rapid Eye Movement (REM) sleep, the stage where most vivid dreaming happens.
During this time, their brain activity closely mirrors what happens when they’re awake. This discovery, paired with evidence from research on other animals, strongly suggests that dogs replay moments from their waking lives when they dream.
One of the most famous experiments on dreaming didn’t actually start with dogs, but with rats. In 2001, neuroscientist Matthew Wilson at MIT studied rats as they ran through mazes. When the rats fell asleep, their brain scans lit up in the same patterns as when they were running, showing they were reliving the maze in their dreams. For dogs, the same logic applies. If they spend their days chasing toys, sniffing the garden, or playing fetch, those activities are likely to reappear in dream form.
But here’s where it gets even more fascinating. Dogs aren’t just running through dream fields and chasing sticks. Because they form such strong emotional bonds with their humans, it’s very likely that their dreams are filled with us—our faces, our voices, even our scent.
Dr. Barrett suggests that dogs may dream about “pleasing or annoying you,” much like how humans dream of interactions with the people closest to us. In other words, when your pup is curled up beside you, they might be lost in a dream where they’re playing with you, waiting for a belly rub, or even replaying that time you came home with their favorite treat.
Not every dream is logical or realistic, though. Just like humans often have strange, exaggerated dreams, dogs might experience surreal versions of their favorite activities. A simple game of fetch could become an endless field of tennis balls, or dinner might appear as a never-ending bowl of chicken. Their favorite objects and experiences may appear in dreamland but with a twist of imagination.
Of course, we can’t ask our dogs what they dream about. As Dr. Barrett points out, the only animals to ever “communicate” their dreams were the famous signing gorillas, Koko and Michael. But clues come from observing behavior. When the brain’s natural mechanism that keeps muscles still during REM sleep weakens, both humans and dogs sometimes act out their dreams. That’s why you may see your dog paddling their legs like they’re running, or barking softly as though chasing a squirrel. The more elaborate these movements, the stronger the evidence that your dog is acting out a dream.
And dogs aren’t the only animals that dream. French neuroscientist Michel Jouvet’s work in the 1950s revealed that cats dream vividly too. When he removed a part of the brainstem that normally prevents movement during REM sleep, cats began stalking, pouncing, and hissing in their dreams—essentially hunting invisible prey.
This research supported the idea that dreams are widespread across mammals, from mice to elephants. While whales and dolphins may be exceptions since they keep half their brain awake at all times, most mammals likely enter dream states similar to ours.
For dog owners, the thought of our furry companions dreaming about us is a heartwarming reminder of the bond we share. From morning walks to evenings curled up on the couch, we make up such a central part of their daily lives that we naturally show up in their subconscious too.
So the next time you see your dog’s paws moving in their sleep, imagine them racing through a meadow with you by their side, or rolling on the floor waiting for you to laugh. And if you want to help your pup have sweeter dreams, experts suggest the same rule that applies to humans: give them a happy, safe, and loving day. After all, good days often lead to good dreams.
It turns out, when dogs drift off into dreamland, they don’t just carry their toys or food with them. They carry us too.
