Dogs are said to have the ability to see spirits and other paranormal entities unseen by man. In spite of this ability, vision is said to be the least sensitive sense of a dog. Our four legged friends are noted to have excellent hearing abilities and ultra sensitive noses but vision of dogs is inferior to that of its human friends.

So what kind of vision do dogs have? In spite of the similarity in genetics, dogs vision is different from humans. There was once a theory that dogs are living in a colorless world as they do not have the ability to see colors. Studies have proven that dogs can see colors but unlike humans that have trichomatic vision, dogs are noted to have dichromatic vision. Due to the dichromatic vision, dogs can only see some colors in the spectrum. Although not scientifically verified, dogs are believed to be able to see only shades of yellow and blue. Because dogs have fewer photoreceptor cones, mans best friends do not have the ability to distinguish red and orange colors.

Dogs see better in dim lights. This ability enables dogs to hunt and capture prey even in the night. Running in the dark at high speed would not be a problem to dogs because of their ability to see in the dark. Dogs make dependable guards not only because of their alert and protective nature but also because of this night time vision. Dogs can see better in the dark because they have the ability to dilate the pupils to let more light in.

Behind the dogs retina is a layer of reflective cells known as tapetum lucidum that has the function of reflecting light so that object the dog see in the dark would appear to be well lighted. Dogs have a more accurate and developed wide angle vision and peripheral vision. Dogs can detect the slightest movement even at a distance.

Dogs though find it hard to focus on the shape of object because they are known to have low visual acuity. These animals can detect movements at a distance but they would not be able to distinguish the shape of the moving object. Dog can see distant movements but objects that can be seen clearly by humans as far as 75 feet will be seen by dogs clearly if the object is only 20 feet away

Dogs indeed see the world in a different manner. Even with its inferior vision, dogs still have the qualities that make them endearing pets.
