Dogs CAN see in colour! The same ones that humans see, but they can't distinguish between green, yellow and orange, thus they have partial color-blindness.
The number of cones in their eyes is low as they are nocturnal (or were as wolves).
Another Answer:
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 spectrum. 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.
Dogs can see in much dimmer light than humans. This is because the central portion of a dog's retina is composed primarily of rod cells that "see" in shades of gray while human central retinas have primarily cone cells that perceive color. The rods need much less light to function than cones do.
Dogs can detect motion better than humans can.
Dogs can see flickering light better than humans. The only significance to this appears to be that dogs may see television as a series of moving frames rather than as a continuous scene.
Dogs do not have the ability to focus as well on the shape of objects (their visual acuity is lower). An object a human can see clearly may appear to be blurred to a dog looking at it from the same distance. A rough estimate is that dogs have about 20/75 vision. This means that they can see at 20 feet what a normal human could see clearly at 75 feet.
Also consider the perspective that dogs see the world from. A dog with its eyes about 12 inches off the ground certainly sees the world a different way than a human with eyes about 48 inches off the ground like many 5th graders.
As humans we tend to think of dog's visual capabilities as inferior to ours. It is different but it may suit their needs better than possessing accurate color vision would.
They do. They're red-green colour-blind, like many humans. Blues and yellows are visible to them.
Becasue people have better sight, dogs have better hearing.
dogs can see fewer colors than people, becasue they can have the ability to think their chew toy is pink when it is actually purple. This disability goes the same ay for color blind people. when they think something is pink it is actually purple.

Dogs do see color, but not like people do. Most colors they cannot distinguish and blur together. There have been a number of controlled studies concerning this.
dogs can see it's just that there color blind. if you don't know what it is, color blind is were you can see but you can only see black and white
No type of dogs can see in colour, I don't know why though.
no they do not seen in b/w they are coulor blind the can see certin coulor's Dogs are dichromatic. Their vision is like red-green color blindness. They can distinguish different shades of grey.
listen idon't want to call you dumb but dogs see in color and well to prove it science people or ecologist just said they candogs can see in color your not dumb but your not an expert of animals there i said what i need to bye call me jay d lol
Humans see with color. Dogs simply have less cone receptors therefore they do not see light. Dogs only see in black and white.
cows cant see color red
yes
No
they do not see color their like dogs they can see black white and gray
Some dogs see a few, but most see black and white
No, dogs see in black and white, most animals(those that hunt at night) can't see colors.
Dogs cannot see in color, so the color of the ball would not be the cause of its fear.
