Dogs can't distinguish colors like humans, but dogs do see certain colors. Dogs are able to distinguish between different shades of blue, indigo, and purple, but they do not have a special sensitivity to high-chroma colors such as red and green in the spectrum.
Dr. Brooks' research in the United States showed that red is dark for dogs, while green is white for dogs, so a green lawn appears to dogs as a white meadow.
The difference between human and canine vision is in the response to light, the human eye responds to the three primary colors (red, green, and blue) that cause various colors.
Although the dog's strength is not good, it has a keen sense of smell. The dog's sense of smell is the first among all animals, and blind dogs can use their noses to live like normal dogs. The dog's sensitive sense of smell is mainly manifested in two aspects:
One is the sensitivity to odors; The second is the ability to distinguish smells.
Sensitivity varies depending on the type of taste, and is about 1,200 times that of the human sense of smell. The dog's nose can distinguish about 2 million different scents, and it also has a highly analytical ability to pick out the kind of scent it is looking for from many of the many scents that are mixed together.
Extended Information: Dog's Eyesight:
A dog's eyesight is only about three-quarters that of a human, and among all animal species, dogs have about the average eyesight. The dog's single eye can only see 25 degrees, so it can't see the closest distance to the front. The dog's eyeball lens is relatively large, distorted like a horse's eyeball, so it is impossible to adjust the sense of distance and proximity, and twenty to thirty meters is about its limit.
Dogs have a special ability to detect moving objects; They are able to detect 70 lines per second, compared to about 60 lines per second for a typical TV screen. When the light is dim, dogs have better eyesight than humans, and dogs are natural carnivores that live by hunting, so they also have considerable eyesight in dark places.
Dogs' eyes can see short-wavelength colors, and dogs' corneas are larger, allowing more light to enter their eyes, making it easier to see in dim light. But in the darkness, where there was no light, the dog could not see.

Are dogs color blind? How many colors can they see?
-
There are blue, black, brown, coffee, gray, red, yellow, green, etc.
The color of a dog's eyes will change, and the color is different when born and when it grows up, but the dog can basically determine the approximate color in about two months.
The innate color of each breed will be different due to genetic differences, and the birth and fixed eye color is regular, which is also related to the color of the coat, and it is a fixed pattern of expression determined by genes.
The change in eye color is related to the pigment of the fundus, just as the color of the eyes becomes lighter as a person gets older. To put it simply, if your puppy's breed only has brownish-yellow eye color ranges, then the puppy will also have brownish-yellow eyes in the future, unless it is inherited by crossbreeding.
If there are several colors in the breed, it depends on the coat and eye color of the dog's parents, and each breed has a genetic map.

1.A dog's eyes can see colors, but not much.
2.Although dogs cannot distinguish various colors like humans, they can distinguish different shades of blue, indigo and purple, but they do not have a special sensitivity to high-chroma colors such as red and green in the spectrum.
3.Although dogs don't see much color with their eyes, their sense of smell and hearing is very sensitive.

The dog's eyes can see color; There are two types of cones on the dog's retina, which can recognize short wavelengths and medium-long wavelengths, that is, they can perceive blue light (light waves with short wavelengths) and red and yellow light (light waves with medium and long wavelengths); To put it simply, it's red-green color blindness. Can dogs see color with their eyes? The dog's eyes can see color; There are two types of cones on the dog's retina, which can recognize short wavelengths and medium-long wavelengths, that is, they can perceive blue light (light waves with short wavelengths) and red and yellow light (light waves with medium and long wavelengths); To put it simply, it's red-green color blindness.
1.The dog's eyes can see color;
2.Dogs have good eyesight, but they are a little different from humans. Dogs' eyes also have color vision, but color is not very important to dogs.
In the human retina, there are rod-shaped and cone-shaped visual cells. The former is divided into light and darkness (black and white) of the environment, and the latter is divided into colors. Dogs have more rod-shaped cells than cones, so dogs can still see clearly in low-light environments.
It follows from this that even the most colorful things appear in the eyes of dogs only in pastel hues.
3.There are two types of cones on the dog's retina, which can recognize short wavelengths and medium-long wavelengths, that is, they can perceive blue light (light waves with short wavelengths) and red and yellow light (light waves with medium and long wavelengths); Due to the small number of cones, the colors of the world in the dog's eyes are very monotonous, not as colorful as the world in the eyes of humans.
However, there are three types of cones in humans that allow us to see all the colors of light in the visible spectrum. Because dogs have only two types of cones, dogs can distinguish the same colors as people with red-green color blindness.

Eye color distribution in dogs
There are many breeds of dogs, and each breed has a different eye color. Generally speaking, dog eye colors can be divided into brown, blue, green, black, etc.
The most common eye color is brown, which is a result of pigment formation. Some breeds of dogs, such as Golden Retrievers, Labradors, Huskies, etc., have brown eyes that are the most common.
Some breeds of dogs will have blue eyes, such as Australian Shepherds, Corgis, etc. Dogs with blue eyes are more likely to have blue eyes because of the presence of a substance called "crystalline", which makes the dog's eyes appear to be covered with no pigment.
At the same time, the dog's eyes may also be green and black. Some breeds of dogs, such as French Bulldogs, Shih Tzus, etc., have mostly green eyes, while black eyes are caused by black qualities, such as butterfly dogs, Yorkshires, Chihuahuas, etc.
Changes in eye color related to dog breed and age
As dogs age, their starvation eye color changes. Puppies' eyes may be light blue, gray, or green, which is due to the birthmark hormone in the mammalian newborn's body, and these colors can gradually darken and darken over time.
Some breeds of dogs also have a change in eye color when they reach adulthood, such as corgis. Corgi usually have blue or light gray eye color during their puppy years, while in adulthood, their eye color changes to dark brown or black.
Also, some breeds of dogs can change their eye color after being sick or injured. This change is usually an indication that the dog has an abnormal condition in its body and needs to seek help from a doctor in time.
The relationship between a dog's eye color and personality
It is widely believed that a dog's eye color is related to its personality. For example, most dogs with brown eyes are gentle, friendly, loyal, and can form close bonds with humans, such as Golden Retrievers and Labradoodles; Blue-eyed dogs, on the other hand, are loyal, friendly, and lively, but some are slightly timid, such as Australian Shepherds and Corgis.
Black-eyed dogs usually have a determined, confident, and courageous personality, but they are also more independent, such as Doberman Pinscher and Chihuahua, etc.; Green-eyed dogs are more gentle, loyal, and witty dogs, such as border collies and hunting dogs.
Summary
In conclusion, a dog's eye color varies from breed to breed, while eye color can also change as the puppy grows, becomes an adult, gets injured, or becomes sick, etc. The relationship between a dog's eye color and its personality is also a topic of great concern. Understanding these helps owners to have a deeper understanding of their pet's personality and characteristics, and is an important information for dog owners to form a better way of dominating.
