This is how dogs see the world

There are many aspects of dog life that humans are not yet aware of. A common question is how dogs see the world.

Unlike humans, whose vision relies on a wide range of colors, dogs see the world in a more limited palette. Despite this, they have a great ability to detect rapid movements and excellent night vision.

What colors do dogs see?

Some popular beliefs hold that dogs see black and white. However, according to the Villoria Ophthalmology Clinic in Spain dogs see colors but “with a different spectrum” than humans.

National Geographic explains that while humans have 3 types of cones that allow us to perceive colors, dogs only have 2. Here’s why They can only distinguish shades of blue and yellow Therefore, your ability to see colors that deviate from this range, such as red and green, is practically zero.

How well do dogs see in the dark?

THE Dogs have 4 or 5 times greater night vision than humans because they have a greater number of sensory cells in the retina that allow the visual perception of light. These are called canes.

This is why dogs have better vision than people at night. However, it should be noted that there are also other factors, such as the large size of the retina, that contribute to having good night vision.

What viewing angle do dogs have?

Dogs’ viewing angle varies depending on the size of their muzzle. Those who have had it for a while have a field of view wider than it could reach 270ºwhile those with a short snout only reach 180º, a figure similar to that of humans.

However, small-nosed dogs have the ability to focus on objects better and make eye contact with humans.

Dogs can easily detect movement

The canes are also responsible for the canines having a excellent ability to distinguish moving objects or people. Because they have more rods in their eyes than humans, they are able to process images at a higher frequency, which is why they prefer moving objects.

However, their ability to distinguish things when they are still is minimal. This is when your sense of smell kicks in and is complemented by your sight.
