When we have a dog at home, one of the main curiosities is understanding how our furry friend sees the world, objects, or ourselves. Who knows if they have more developed eyesight than ours, how they perceive shapes and colors, how to keep their eyes clean, and how much of the surrounding environment they can distinguish during the night?
How do dogs see? The peculiarity
Obviously, both dogs and cats have a unique way of perceiving the world around them, distinct from our human vision, even physiologically speaking. In fact, they have extended binocular vision, with a visual field of about 240 degrees, much wider than ours. This wider field of vision depends on the position of the dog's eyes, which are located laterally in relation to the muzzle. Their peripheral vision is certainly better than ours, but unlike us, they perceive an object only at a distance of 40 centimeters.
Close-up vision is not particularly developed at night, when the lack of light makes it even more difficult to focus and identify objects that are relatively close to the pet. However, they have excellent visual ability from afar, both at night and with moving subjects. A simple and practical example: how skilled is your dog at catching a ball that you throw at them, even unexpectedly?
Can dogs see colors?
Let's debunk a myth about Fido: dogs don't see in black and white, but perceive colors less sharply and intensely than us. In detail, our four-legged friends can indeed see colors, but mainly in shades of gray, yellow, and blue.
The retina structure is the main difference in color perception between humans and dogs. While the human eye has three types of cones to distinguish red, green, and blue colors, dogs have only two, resulting in dichromatic vision. In other words, they see yellow and blue better, whereas they have difficulty distinguishing colors like green, red, and orange.
How to clean dogs' eyes?
We must properly care for dogs' eyes, which are one of their most important senses.
In the presence of small foreign bodies, such as dust, you can use gauze soaked in physiological eye solution; it's better to avoid cotton or even toilet paper, which can easily irritate the dog's eyes. Your veterinarian should examine conjunctivitis, cherry eye, or other eye conditions immediately.
