Can Dogs See Color? Five Senses In Dogs ( Detailed Information)

Estimated Reading Time:

Dogs are known for their keen sense of smell and ability to detect human emotions, but what about their vision? Can dogs see color? You may have heard that dogs don't see the full range of colors perceptible to humans. The article below will cover how dogs see colors and fun facts about canine vision.


Can Dogs See Color?

Main question: can dogs see color? In short: yes, dogs can see colors. The world does not appear to them only in black, gray, or white. But they don't see colors exactly like humans. Their range is limited to blue, yellow, and shades of gray. Generally, they cannot distinguish between shades of green or red.

This peculiarity is explained by the structure of the dog's eye, which is different from that of humans. All light is processed through the eye into the retina. The retina has cells called cones and rods, which are photoreceptors responsible for color perception. Humans have three types of cones, but dogs only have two, which limits the range of colors they can see.

Can Dogs See In The Dark?

We learned the answer to whether dogs can see color; so, can dogs see in the dark? The differences between dog and human vision are not limited to color perception. The eyes of dogs and humans have evolved differently to meet their respective needs better. For example, humans are a diurnal species, meaning their waking hours are concentrated during the day when it is bright. On the other hand, dogs are crepuscular, so they are most active at dawn and dusk when the light is low.

How is your dog's vision affected? In short, your dog sees much better than you at night and in low-light conditions. This is because your dog's retina has more rods than yours; these cells are responsible for motion detection. Compared to cones, rods can also pick up visual signals at lower light levels. So, biologically, the high amount of rods in their retinas and their ability to detect movement in the dark made wild dogs better at stalking their prey at night.


What Is A Dog's Field Of Vision?

Let's say you and your dog look at your backyard from the same point of view. Even disregarding colors, you might be surprised at the differences between what you see. This is because dogs have a much wider field of vision due to their increased peripheral vision.

Humans have a peripheral vision of around 180 degrees, but dogs can see up to 240 degrees around them. So it is not far away from a panoramic vision! Why? Their eyes are forward-facing. Like all predators, they have a lateral position on their heads, giving them a wider field of vision.

Furthermore, humans can see farther than dogs. Dogs are thought to have 20/75 vision, meaning they can see an object 20 feet away like a human with 20/20 vision would at 75 feet. To locate things at a great distance, dogs rely much more on hearing and smell than vision.

Can Dogs Watch Television?

If you've ever watched TV with your dog curled up next to you on the couch, you've probably wondered if he could see what was happening and understand what he was staring at. Unfortunately, there's no way to tell if your dog loves the action and characters from your favorite shows as much as you do, but we have an idea of ​​what he sees when he stares at the screen.

Your dog can see what appears on the screen, except for shades of red and green. However, the frame rate of your TV determines whether it sees smooth images or not. To see a soft image on the screen, humans only need a frame rate of 60 frames per second; dogs need a minimum of 70 frames per second. In other words, your dog might not be interested in an old TV, but he might be as enthralled with your shows as you are if you have a newer model with a higher frame rate and resolution. 


Do Some Dogs See Better Than Others?

It turns out that one breed of dog sees much better than the others: Greyhounds. These dogs have been bred over several generations to hunt by sight rather than scent, which sets them apart from most other breeds. This particularity offers them several biological advantages.

Greyhounds have a field of vision of up to 270 degrees, which is 90 degrees more than humans. The central area of ​​their retina, where there is a high concentration of horizontal cones, is also larger. In addition, Greyhounds have longer muzzles than other dogs, so their central retina area is wider, and their vision is superior.

Five Senses In Dogs

Despite the popular belief that they only see in black and white, dogs see the world in color, although it is not similar to our vision.

Our vision has three colors; theirs is only two. Dogs can only see the colors yellow and blue-violet, so they perceive red and orange as if they were shades of yellow, and they do not differentiate green from white or blue-green from grey. In addition, our eyes perceive colors intensely and brilliantly while they see poorer colors and pastel tones.

But sensitivity to colors is not the only trait that differentiates our senses from theirs:


In the past, dogs hunted at dawn and dusk, developing a strong sensitivity to light that allows them to see in low light. This is possible thanks to a large number of receptors that activate with little light and the presence of this structure that acts as a mirror reflecting the light inside the eye and causing a major stimulation of the retina. For this reason, their eyes take on a greenish-yellow color when photographed with the flash at night.

The dog's eyes are also very sensitive to movement, especially in dim light and at a great distance. On the other hand, their vision is more blurred than ours.

Another difference between their sight and ours is that of the visual field: our eyes have a frontal position, and the visual fields of the two eyes overlap in a large space called the binocular vision zone, thanks to which we have the sensation of seeing in three dimensions. In contrast, many dogs have their eyes in a more lateral position. This causes them to have a more peripheral vision but a reduced area of ​​binocular vision. Thus, to correctly measure the distance of an object, they must orient the head so that the object enters the zone of three-dimensional vision.

Their hearing is more sensitive than ours: they can hear sounds at a distance four times greater and pick up ultrasound (sounds so high-pitched that they remain outside our detection threshold). In addition, thanks to the independent movements of their ears, able to rotate until they find the origin of the sound, dogs can precisely locate the source of a sound, which is an excellent help for hunting.


With almost 280 million receptors, dogs' sense of smell is much more developed than ours, which has only 5 million olfactory cells. Their sensitivity varies depending on the breed, size, and odor in question but can become more than 100,000,000 times greater than ours. This means that dogs need a lower concentration of odor particles in the air to detect their presence. Their sensitive sense of smell also allows them to recognize components in very complex chemical mixtures. This sensitivity is used by dogs trained to detect the smells of certain substances such as drugs, explosives, etc.



Dogs can tell the difference between sour, bitter, sweet, and umami flavors, but they cannot detect salty. In addition, on the tip of the tongue, they have specific receptors for savoring water. However, their ability to perceive flavors is generally much less developed than ours, considering that they have 1700 taste buds while we have 9000. Dogs compensate for this "disadvantage" with a very developed sense of smell. In addition, compared to us, they have a much more developed sensitivity to the umami flavor: foods with this flavor are rich in proteins and amino acids, such as meat and dairy products. This significant sensitivity reflects their dietary preferences.


The skin of the whole body is the seat of touch. There are different types of receptors in the skin that can detect pressure, temperature, and pain. However, sensitivity is not the same on all skin, with the nose and pads susceptible areas. In addition, dogs have a few special hairs called vibrissae that increase tactile sensitivity on certain parts of the body and thus compensate for their dense coat. Whiskers are long, stiff, and extremely sensitive hairs found beside the nose, above the eyes, on the cheeks and chin, and below the jawline. When they touch surrounding objects or vibrate with air currents, whiskers give the dog information about the space around him and help him move around without bumping in low light.

Dogs are what they are due to their evolution: their senses have developed in a long history of adaptation to their environment, and although today the majority of dogs have someone to provide for them, their senses continue to speak of these ancestors who needed a fine sense of smell, an eye sensitive to movement and a developed sense of hearing to be able to hunt.
