do dogs see colours?

Answer 1

A number of studies have been done to investigate the color vision of dogs, and the results have been conflicting. However, more recent, better controlled studies indicate that dogs do possess and use color vision, but not to the same degree that humans do. The photoreceptor used for color vision is the cone, and there are cones present in the canine retina. However, they are present in low numbers, comprising less than 10% of the total photoreceptor population in the central area of the retina, as opposed to the human retina which consists of nearly 100% cones in the fovea. Two distinct type of cones appear to be present in the canine retina. One type is maximally sensitive to light in the wavelength that appears violet to people, and the other type is maximally sensitive to light in the wavelength that appears yellow-green to people. Thus, it appears that the visual spectrum of color in dogs is divided into two hues; one in the violet and blue-violet range, probably appearing as blue, and the other in the greenish-yellow, yellow, and red range, which is probably seen as yellow. Light that appears blue-green to people probably appears as white or shades of gray to dogs. Dogs are unable to differentiate colors that appear as green, yellow-green, orange or red to people, and are unable to differentiate greenish-blue from gray. This is similar to people who are red-green color blind. However, one study indicates that dogs are better able to differentiate between subtle shades of gray than people, which would be advantageous in increasing visual discrimination in low light conditions, where insufficient light is available to stimulate cones.

Answer 2

Dogs do see color, but in a more limited range than that seen by normal humans, who see the rainbow of colors described by "VIBGYOR": Violet, Indigo, Blue, Green, Yellow, Orange, and Red (plus hundreds of variations on these shades). Instead, dogs see "VIBYYYR" (Violet, Indigo, Blue, Yellow, Yellow, Yellow, and Red). The colors Green, Yellow, and Orange all look alike to dogs; but look different from Red and different from the various Blues and Purples. Dogs are very good at telling different shades of VIB apart. Finally, Blue-Green looks White to dogs.

Answer 3

Im my opinion yes...

See humans compare the world to themselves. So we say dogs dont see in colour because they do not have the cones that we do in our eyes that makes us see in color but just the cones that help us see shades of grey. In my opinion they can probably see in color but their base colours are different than ours and are colours we cannot see.

I mean we're only human and technically only see in 3 colours

Answer 4

Dogs do see in color, but their perception of color is not the same as it is for people. They cannot distinguish between red, orange, yellow or green. They can see various shades of blue and can differentiate between closely related shades of gray that are not distinguishable to people.

When comparing dog and human vision, people are better at depth perception, color perception and seeing minute details of an object. Dogs are better at seeing in dim light, responding to an image rapidly and detecting the slightest motion. They also have better peripheral vision.

Answer 5

Generally, all predators can see in some form of color vision. Herbavores generally see in black and white. You can tell the difference by eye placement. Predators have their eyes pointing to the front, while prey animals like deer or rabbits have eyes on the side of the head for better side and rear vision.

Dogs and humans both see colors, and so are both designed to be predators.

Answer 6

Some people say no, but I wouldn't really be sure because, after all, they aren't dogs. Only a dog would know.

Answer 7

I've read in several pet magazines (while waiting in the vet's office) that they in fact CAN see colors, but the exception is red. Instead of seeing the color read, it's replaced with either yellow or green (other things that are naturally yellow or green stay their normal color).

Answer 8

no they don't. the way i know this is because my dog has a squeaky toy bone. on one side there is a hole for the air to come out of when squeaked. this side is green. she prefers the other side which is red so the air doesn't blow into her mouth. this side is red. every time she goes to play with it, she'll pick it up and squeak it. if air blows into her mouth she will drop it and pick it up on the other side. if she could see colors, wouldn't she just pick up the red side every time?

Answer 9

I have always heard that dogs were color blind...I just want to know where the dog is that told them this

Answer 10

no one is shure but some scientests say they can see in black, white and shayds of grey like an old time movie but they can see faint colours of red and green
