Is the dog color blind and only black, white and gray in his eyes?

Personally, I think this statement is wrong, I think dogs are things that can see colors, because I found that my dog is very excited when he sees red, so I think he can see other colors.

No, dogs are not completely color blind, they are just color weak, they generally rely on smell and hearing to distinguish people and things, but they also have a certain understanding of color, not completely black, white and gray.

I don't think so. If a dog is colorblind, then the degree of color blindness is not the same. Dogs with different color blindness have different colors in their eyes.

There are not only three colors in the eyes of dogs, black, white and gray, but the dog's eyes can be seen colorful, but compared with humans, they are still not as rich as human vision.

Dogs can see colors, but there is no way to see the full-color spectrum like humans, and the colors they see are not as many as humans, and they are not as rich as humans. However, some dogs are the same as humans and will have color blindness, which is also a congenital genetic disease.

Can dogs see colors?

When many people think of dogs, they think that dogs are colorblind and can only see gray and black. This perception is wrong, dogs can actually see many colors, but they don't see as many colors as humans. This is not nonsense, there is some scientific basis for this, and it is proven by relevant experiments.

Dogs' eyes, as well as human eyes, contain a special type of light-trapping cell, which has become known as cones, which allows our eyes to respond differently to different colors. And this response is transmitted to the brain, which recognizes different colors. Therefore, dogs are also able to see a lot of colors, and when they see different colors, they will also show different reactions.

Why are some dogs color blind?

This situation is also very normal, after all, dogs and human visual cells are very similar, and some people will also have color blindness, so dogs will also have color blindness. So some dogs are not able to see colors, they can only see black and gray, their world is very dark. When we see colorblind dogs, we don't discriminate against these dogs, which are also pitiful.

However, dogs don't know that they are colorblind, because dogs are not as conscious as humans. Therefore, when raising a dog, we must treat the dog well and give the dog a sense of security, so that the dog can be happier and happier and can accompany us for a long time.

Summary. If you don't believe that your baby can see a lot of colors, you can also do an experiment at home. For example, buy toys of different colors for your dog and let the dog choose the color he likes, so that you can judge that your dog can recognize different colors.

Dogs can't see color. Because the dog's eyes are different from the human eye, there are very few cones in the dog's eye, so the dog is color blind.

Of course, you can see the colors. It may be innate, it may be genetic, it may be color vision fatigue or it may be dark.

You can see the colors, because there are two kinds of cells on the dog's retina, and they don't have as many colors as we humans see.

Dogs are not color blind.

Although dogs are not as strong as humans in distinguishing colors and cannot distinguish long-band light waves, dogs are not colorblind and can see black, white, gray, blue, yellow and other colors. Dogs have a weak color and will perceive green as off-white and red as black or brown. Therefore, dogs are not colorblind.

Guide dogs can distinguish between traffic lights. Guide dogs do not distinguish traffic lights by color, but rely on the brightness of traffic lights to distinguish them. This is because there are only two types of cone cells on the dog's retina, which causes them to not be able to distinguish many colors, but different colors are not without difference in the dog's eyes, but the difference is in brightness.

How dogs distinguish colors

There are two types of cones on the dog's retina, which can recognize short-wavelength and medium-long wavelength light waves, that is, they can perceive blue light, that is, light waves with short wavelengths, and red and yellow light, that is, medium- and long-wavelength light waves. Due to the small number of cones, the color of the world in the dog's eyes is 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.
