Dogs sight?

Question

Do dogs really not see color?

Answer 1

The innermost tunic of the eye is the nerve tunic or neural retina.

The photo receptors, the rods and cones, are located near the outer aspect, immediately inward from the pigmented epithelium.

The retinas of domestic mammals contain mostly rods and the retinas of domestic birds contain mostly cones.

The rods are the photo receptors associated with black-and-white vision, and the cones are those associated with color vision. The rods are extremely sensitive to light and are used for night vision, whereas cones function best in day vision.

Dogs and cats can see yellow, green, ad blue but have very few cones that respond to the longer wavelengths of orange or red light.

Answer 2

Dogs are said to have dichromatic vision -- they can see only part of the range of colors in the visual spectrum of light wavelengths. Humans have trichomatic vision, meaning that they can see the whole sprectrum. Dogs probably lack the ability to see the range of colors from green to red. This means that they see in shades of yellow and blue primarily, if the theory is correct. Since it is impossible to ask them, it is not possible to say that they see these colors in the same hues that a human would. Whether or not the ability to see some color is important to dogs or not is hard to say.

Answer 3

dogs see colors the way a colored blind person sees colors

Answer 4

i do not know....


but i would guess they do have some sort of stunted eye sight compared to us, hence the elevated hearing and smell....
