Since ancient times, dogs have been our friends and live in families. It is not surprising that people are so interested in the details of how their body is structured and how it functions, what is the psychology of the four-legged pet. Scientists, veterinarians, zoopsychologists have been studying all this for a long time.
For example, here is one of the questions that people are interested in: “How do dogs see?” Although scientists have already received an answer to it, not all owners and breeders know it. The explanations often contain incorrect information, many myths are walking among the owners about the sight of dogs.As in humans, a special organ, the eye, provides visual function in pets. He is paired, all animals have two of them. The basic structure of the organs of vision is the same in humans and dogs. However, there are differences.
How do dogs see during the day?
In general, their daily vision is no better than human. But for a predator this does not play a big role. The structure of their eyes, as well as of the whole organism, is maximally adapted for other purposes, due to their lifestyle.

However, they are able to distinguish between shades of gray. This is due to the presence of a larger number of sticks and their increased sensitivity. The dog owes the same peculiarity to its exceptional ability to see a moving object far away. Due to the location of these receptors close to the optical axis of the eye, where people have a “yellow spot” with congestion, the pet determines the distance much better than a person. Nearby, the animal does not see very well: all objects at a distance of less than 30 cm are already blurring.By the way, the visual fields in dogs are elongated, oval (in humans - round), and the axis of the eyes are not parallel to each other, but diverge at an angle of about 20 degrees. This greatly expands the pet review. Of course, in breeds with a short muzzle, this indicator approaches that of a person.
