How dogs see the world

Investigating how things look from a dog’s-eye perspective

As any dog owner knows, our canine companions can be super empathic, intuitive, and – in a lot of ways – similar to us. Let’s be honest, who hasn’t been able to relate to their dog running to the door in excitement, to greet a special visitor? Or jumping for joy at dinner time?

But even though our four-legged friends are so warm and relatable, there are a few important differences in how we, and they, see the world.

Let’s take a glance at how things look from a dog’s-eye perspective.

What’s canine eyesight like?

On a basic level, the anatomy of a dog’s eye is similar to the anatomy of a human eye. They have upper and lower eyelids, a pupil, lens, cornea, iris and retina.

Much like us, a dog’s retina also includes two types of light-sensitive cells, known as ‘rods’ and ‘cones’. A key difference, though, is that dogs have far fewer ‘cones’ (that are involved in color perception and detailed vision), and far more ‘rods’ (that are involved in motion-detection, and vision in dim light).

Dogs also have a layer of tissue in their eyes that we don’t have, called the tapetum lucidum, that reflects light into the retina.

Here’s what some of these differences mean…

Dogs can see color (but not as much of it as us)

The old stereotype is that dogs only see in black and white, but that’s not actually true. Not only do dogs see in color, but they can comfortably tell the difference between a variety of different colors and shades.

All the same, though, dogs don’t see as much color as we do.

Human beings have what’s known as ‘trichromatic vision’. This means that we see three colors – red, green, and blue – and the many different shades between them.

Dogs, on the other hand, have ‘dichromatic vision’. This means they only see two colors, and – in their case – they lack the ability to see red.

With dichromatic vision, dogs still experience a pretty colorful world. But since they don’t see shades of red, they’re not getting as much of a vibrant view of the world as we do.

Dogs can’t see as far as us

The average human should generally have 20/20 vision, unless they’ve got some level of myopia. Dogs, though, have something more like 20/75 vision on average. Basically, this means they just can’t recognize objects as far away as we can.

Dogs have night vision we could only dream of

Although it’s usually cats that get all the praise and recognition for their great night vision, canine night vision is nothing to sniff at either.

Between the higher number of rods in a dog’s retina, and the tapetum lucidum reflecting light into the retina, dogs have great night vision – definitely way better than we could ever dream of.

Dogs have a great field of vision (and they’re very good at spotting movement)

Dogs are very sensitive to motion – which, again, seems to be linked to the high number of rods in their retinas. Small movements in the grass, or small changes in your posture, are likely to be very noticeable and meaningful to your pup.

As well as this, dogs also have a great field of vision compared to us. Their wider-set eyes mean they don’t see things as precisely as we do, but they have significantly better peripheral vision. Put this together with their great motion detection, and dogs tend to be very alert to what’s happening around them.

Dogs ‘see’ a lot more of the world through their other senses

If you’ve ever used a dog whistle, you’ll know that they can work like magic. One moment you’re blowing through a tube that seems to create no sound, and the next moment your four-legged friend comes racing into the room like they’ve just appeared out of thin air.

It’s not a secret that dog whistles work because they emit sound in the ultrasonic range – and dogs, with their super-acute hearing, are able to hear sounds that we can’t.

When we’re discussing how dogs ‘see’ the world, it’s important to realize that there’s more to the picture than just the sense of sight itself.

As well as having highly acute hearing, dogs also have a very powerful sense of smell – which is why they’re used for all sorts of important work, from detecting bombs, to tracking missing people.

Even more amazingly, dogs may ‘see’ with their other senses in more than just a metaphorical way. A 2022 study published in the Journal of Neuroscience found evidence of strong connections between a dog’s sense of smell and the visual centers of the brain. The implications of this research still need to be explored, but it looks like there’s a lot more to how our canine companions experience the world than at first meets the eye.

How do dogs see us?

When we look at our dogs, we generally see lovable, loyal bundles of fur, who are thrilled to greet us when we get home after a long day at work.

But how do our dogs actually see us?

Your dog really does think you’re amazing

In news that isn’t likely to surprise anyone, our canine companions do seem to legitimately like us. One 2015 study found evidence that the reward centers in dogs’ brains light up when they smell familiar humans. The surprise twist? This phenomenon didn’t happen when dogs smelled familiar dogs, or when they smelled strange humans. There’s just something extra rewarding and heart-warming to dogs, about the scent of their very own humans.

Your dog isn’t too interested in looking at your face (but they’re still good at reading your facial expressions)

It may be strange or even upsetting news for dog owners, but our four-pawed friends don’t seem naturally very fixated on faces. In fact, a 2020 article in the Journal of Neuroscience found that – unlike us – dogs showed no difference in brain activity when looking at a face, versus the back of a head.

At the same time, other research has found that dogs excel in reading human social cues, including facial cues. So, even if they’re not naturally too focused on faces, our dogs still seem to put in some real effort to notice and understand our expressions.

Ultimately, it seems like our dogs take a whole lot of interest in us. It’s just that they prefer to focus on different social cues and sensory details than we do.

Your dog knows you’re not a dog

We sometimes assume that dogs see their owners as other dogs… just strange dogs with weird posture and opposable thumbs.

Considering the evidence that dogs react differently to other dogs than they do to humans, though, it’s a pretty safe bet that your canine companion knows you’re not the same species. They’re just good-natured enough to not hold it against you.

It’s important to keep your dog active so they can keep experiencing the wonders of the world

As we’ve touched on throughout this article, dogs see and relate to the world around them in a very direct and experiential way. Instead of just viewing a fascinating new landscape, or a new friend-to-be, primarily with their eyes, your dog revels in exploring all the sounds, smells, and tactile experiences involved in every moment.

This is just one of the many reasons why it’s important to keep your dog physically active throughout their life. Because, for our canine companions, going for a walk through a beautiful field or down a forest trail is about so much more than just getting some exercise. It’s about really ‘seeing’ the world in all its richness.

Has your dog recently seemed more withdrawn from the world and less interested in their surroundings? Maybe they’ve haven’t been as excited about going for walks? If they have, joint stiffness could be to blame. Consider giving them YuMOVE Joint Care PLUS, our high-strength joint supplement, scientifically proven to work in just 6 weeks.*
