If you’ve ever caught your dog staring into the middle distance and wondered what’s going on behind those puppy-dog eyes, then congratulations, you’re not alone. The short answer is: probably something simple, immediate, and rooted in their senses. But the long answer? Well, that’s where things get interesting.

Do Dogs Have Consciousness
First, let’s get the big existential question out of the way: do dogs even have a mind in the human sense? Behaviorists used to say “no,” arguing that everything dogs do is just stimulus-response. But modern research says otherwise.
Thanks to advances in fMRI scanning and studies, we’ve now seen images of fully awake dogs responding to signals in the reward center of their brain, just like humans.
According to Dr. Stanley Coren, a leading expert on canine cognition, “Since there are significant differences between a dog’s senses and a person’s, we must first explore what passes through the dog’s senses. It is this sensory information that determines the canine view of reality and ultimately shapes the dog’s way of thinking about the world.”
And that sensory input is pretty different. Dogs see fewer colors but detect movement better than we can. Their noses are over 10,000 times more sensitive. Their hearing is finely tuned to high-pitched sounds. So while they may not be pondering quantum physics, they’re absolutely processing a world rich in scent, tone, motion and behavior.
What Goes Through a Dog’s Mind
A Reddit user summed it up bluntly but accurately: “They don’t really think. But they’re constantly trying to read other people’s/animals’ behaviors and body language.”
And to some extent, this is spot on. Most of the time, you can tell what your dog is thinking about just by observing what they’re doing.
For example, if your dog is playing fetch, they’re probably thinking about the ball. If they are drooling next to your pizza box, they’re probably thinking about pizza. If they’re doing zoomies when you pick up the leash, they’re probably thinking about going for a walk.
They may not be thinking of these things in words, like we do. But they can think of it in terms of the sensations they feel when they perceive something. In short, their thoughts are closely tied to the present moment, and they often revolve around you.
So, dogs aren’t mindless. Research shows they have emotional responses, preferences, and even anticipation. One study showed dogs could learn to associate certain smells with rewards, triggering dopamine release in the brain’s pleasure centers.
Another showed they pay more attention to gibberish words than to familiar ones, suggesting they’re trying to decode new human signals, not just reacting to trained commands.

What Do Dogs Think of Humans
Humans are the center of a dog’s world, and probably the subject of many of their waking thoughts. This is both because they love us and because we are tied to all their favorite things. We feed them, play with them, take them for walks, and give them cuddles. So, it’s vitally important for dogs to think of us all the time and try to anticipate what we do next.
Studies have shown that the part of a dog’s brain that lights up for reward also lights up when they hear their parent’s voice. Dogs also respond to our tone, posture, and emotional states. They even appear to recognize and respond differently to happy vs. angry faces.
Some studies suggest dogs experience a rudimentary form of jealousy when their owner gives attention to another dog, even if that dog is a mannequin.
They may not philosophize about their bond with you, but they are keenly aware of you. That’s part of what makes them hyper-social. It also explains why your dog may follow you to the bathroom, stare at you while you eat, or nap in a way that ensures they’ll hear the fridge door open.
It’s this intense focus on humans that drives so much of their behavior. And if they ever need you in return, having a safety net like Petcube’s Emergency Fund can be a literal life-saver. Because dogs don't worry about vet bills, but we sure do.
Conclusion
So what do dogs think about? In short: smells, movement, routines, you, food, more food, and you again. Their thoughts may not be complex, but they’re constant. They live in the moment, tuned to every sound, signal, and scent. And their mental energy is spent decoding what it all means in relation to the things that matter most: safety, companionship, and snacks.
