Can Dogs See in the Dark?

Most people think that dogs have an undeveloped olfactory system and therefore a weaker vision. When talking about seeing in the dark, cats are considered to be the best night-crawlers due to their enhanced nightly vision.

But the truth is that dogs have the ability to see in the dark quite similar to the cats. The eyes of dogs are really adaptable and that improves their night vision.

While our blog’s mascot is a Cavalier King Charles Spaniel, these tips apply for any breed.

Can Dogs See in the Dark?

One of the pros is that dogs have large pupils which allow more light to go through the eye. The two main cells responsible for receiving information in the olfactory system are cones and rods. People have more cones and thus perceive the colors of the environment in a more detailed and distinct manner. Dogs, on the other hand, have far more rods than humans do. Rods are cells that function better in dimmer light in comparison to the cones. The smaller number of cones doesn’t mean that dog’s are color blind, as this is one more myth.

Anatomically speaking the distance between the retina and the lens is greater in humans than in dogs. Closer positioning means that the image created on the retina will be brighter, even when the light is dim. A tapetum is a specific part of the eye in dogs located in the back part. This anatomical part works as a mirror that reflects light. Many scientists think that the tapetum is what makes a dog’s eyes glow in the dark. Besides the initial registration of light, this ‘mirror’ sends bright information to the retina once more and the details in the image improve. Compared to us, humans, its assumed that dogs see five times better in the dark.

The fovea is a small indentation in human’s retina making it possible for us to see the surrounding in vivid detail. But also, there are some downsides regarding the fovea. Because we so complicatedly form the details we are unable to track motion that well. And guess what? Dogs lack this anatomical part in their eyes. With this their tracking motion is enhanced by making it possible to tracks movement on long distances. So we can conclude that even though dogs lack the ability for details and see the images in a blurrier focus they don’t really need to. Evolution has played its role in making their olfactory system useful for the things that help them survive in the environment.

Can Dogs See in Total Darkness?

This question can depend on your dog, but it turns out it may also depend on just how dark it is in the house. Dogs do have better night vision than people in very low light situations. This is because they have a special structure in the back of their eyes that reflects more light to the retina.

Generally speaking, all dog breeds perceive the world differently, but their abilities to perceive the spectrum of colors in the dark setting are roughly similar. The two main anatomical features responsible for the different eye-sight are the length of the snout and the position of the eyes. There is a larger overlap of the visual field for dogs that have a shorter snout and eyes positioned closer to each other. Depth perception is increased when the overlap increases creating a binocular vision.

Can Dogs Tell the Difference Between Light and Dark?

Dogs’ ability to see in darkness stems from the structure of their eyes. They have large pupils, which let in more light. … The human retina has more cone cells, which distinguish color, while dogs’ retinas have more rods, which need much less illumination to detect the gray spectrum.
