Do dog see in dark?A question that many will have asked themselves: Could dog see in low light conditions or in total darkness? The answer is Yes, but with some distinctions.

The Vision of dogs at night
The human being is absolutely ill suited to living in darkness. We live in always-lit environments, and some people even need a bedside light to be able to fall asleep in peace. We even coined a term to describe fear of the dark: acluophobia.
The same thing cannot be said of our furry partners.Their ability to see in the dark, although not on par with that of cats, far exceeds that of humans.
This is possible thanks to Tapetum lucidum , that is a reflective layer placed immediately behind, and sometimes inside the retina, which allows to increase the amount of light that can be captured by the retina itself.
Interesting fact of dog in the dark?
Have you ever noticed that when photographing a dog at night with a flash, the eyes always look haunted? Don't worry, it's the tapetum lucidum,Here is a pictorial Example.
Dogs Natural cameras have many more rods than the human eye, but it only has two types of cones (the human eye three). This means that also gives the wide dilation of the pupils, the dog can see better than a human being even in very dim light, but distinguishes a smaller number of colors.
Ability of dogs to sense moving objects at night
Along with night vision, another amazing ability of our dogs is to sense anything in motion. The rods , in addition to the ability to see in the presence of low light, are in fact also responsible for the ability to perceive moving objects.
Thinking about it a bit, it is not so absurd that dogs have developed these two extraordinary abilities over the course of their evolution.
Their survival depended on the ability to identify and capture prey in order to feed (especially at night).
Dog eyes are able to capture and process images in a way that resembles the operation of burst cameras , whereby their vision becomes similar to a slow sequence of images.
In a study carried out in Great Britain in 1936, 14 law enforcement dogs were examined. The experiment showed that dogs were able to recognize a moving object from a distance of about 900 meters, but found it very difficult to recognize the same object if it were motionless at a much closer distance.
This also explains why dogs make a lot of use of their olfactory organ by being in front of objects at close range. They are perfectly able to fill with the sense of smell the difficulty they have in focusing on very close objects.
