what do dogs see
Most dog owners have probably wondered, What can dogs see? What are the differences between what dogs and cats can see? In fact, for a dog, the eye is much smaller and has a very distinct shape, much like the human eye.
The blurry world.
For dogs, the world appears to be very blurry, in colors of yellow and blue, and less defined than it is for us. We can see some general shapes, but even those shapes can be more difficult to recognize. For example, while most cats will recognize a familiar dog or cat, if we place a red dot on their nose, they will see it only because of their sense of smell rather than their vision. This is similar to what happens to our eyes when we use too large a lens or are near a bright light.

Trouble in seeing the far distance.
Dogs and cats have different ways of dealing with light and their vision, and there are some interesting differences in the areas where their eyes tend to focus. While both dogs and cats have relatively good peripheral vision, (they can see things not in front of them and just behind them), dogs have trouble seeing in the distance. Their eyes seem to move so quickly that they can not see a distant object more clearly than a light source that is behind them. On the other hand, Cats eye has better peripheral vision and sees things far away with more clarity. It is as if their eyes can see the objects of sight in two separate frames.
Increased peripheral vision compromises the amount of binocular vision. Binocular vision occurs where the field of view of each eye overlaps. Binocular vision is necessary for depth perception. The wider-set dog eye has less overlap and less binocular vision (thus less depth perception). This is not an ideal situation as their nose often interferes. Predators need binocular vision as a survival tool. Binocular vision aids in jumping, leaping, catching, and other activities fundamental to predators.
How do dogs eye see during the night?
The light-sensitive portion of the retina is located in the back of the eye. This structure is found in the back of your eyeball. There are two types of light-sensitive cells in the retina: rods and cones. Cones are responsible for color perception and detail sight. Rods can detect motion in dim lighting and provide vision in dim conditions. Rod-dominated retinas allow dogs to see well in dark or low light. Dogs have superior night vision and better motion visibility than people. Dogs do not see color as well as humans because their retinas contain about one-tenth of humans’ cones.
One of the most perplexing questions in animal behavior is what dogs eyes see during the night. Most people have thought that dogs have superior night vision since they are the only animal among mammals with no natural light-sensing organs. However, if you look carefully, most pets don’t have any trouble seeing things at night, even when there’s no moonlight. A sheep, for instance, can see even in dim light, as can a cat.

What colors dogs can’t see?
Dogs can see different colors like color blind humans. Yes, dogs color blind is like. People often believe that someone red/green color blind can’t see any color. However, there are many types of color blindness. Trichromatic vision (three-color variations) is the most common type of normal vision. Red/green color blind people are dichromatic (two-color variations). Dogs’ retinas can distinguish two colors. These colors are yellow and blue-violet. Dogs can also differentiate between different shades of gray. Dogs cannot recognize red, green, yellow, orange, and orange.
Walking with closed eyes.
During the day, most animals walk around with heads bent looking for scents, but not all of them. Only a select few can walk around with their eyes closed. When they need to use their eyes, most animals have an excellent ability to focus on a point in front of them without moving their head. This makes sense because if an animal’s feet are close to its head, then it will have better eyesight than someone who has to look around them to find something.
How does dog see though? Well, scientists have studied how dogs and cats navigate the world. They’ve found that dogs are very good at using peripheral vision. The best example is of a dog following a trail of prey that it has previously tracked. If that dog is followed at a distance, the brain has to work extremely hard to interpret that as nothing more than a dead animal lying nearby.
