It is a common misconception that dogs see only in black and white. Research has found that dogs have colour-sensitive cones in their eyes, but not as many as a human's. Humans with normal vision have 3 types of cones, while dogs and cats have only 2 types of cones so they do not experience the same spectrum of colour vision that we do.
It is thought that dogs can see blues and yellows the best and that they are able to differentiate between various shades of blue and violet, but that they have difficulty distinguishing reds from green. They are considered similar to red-green colour-blind humans.
Another Answer
According to physics and physiology - dogs do nothave as many cones present in the eye compared to a human's eye. Cones are what detects color. So, no they don't see fully in black in white but they don't see fully in color either, but definitely in a limited colour spectrum than full color due to rod/cone ratio. (Rods account for sensitivity to brightness and do not focus in colour). So dogs can see better in low light than a human but less colour, similar to a sepia picture - the yellowish greyish hint to a black and white photo, especially for colors like red or orange. Dogs cannot see red, those cones are not found in animals.

Dogs do in fact see "in color", as shown by the fact that a dog's eye contains both rods (which we associate with B/W vision) and cones (which differentiate between colors). While humans' cones are attached to neurons that react to light at 435nm, 545nm and 570nm, a dog's cones react at 429nm and 555nm. This means that a dog sees somewhat as does a human with red-green color blindness. This means, for instance, that what a human perceives as red, a dog probably perceives as green, and what a human perceives as yellow, a dog sees as a neutral color -- gray.
While rods (which detect light at lower levels but do not tell the brain which color) are widely distributed in humans and dogs, the human eye has more cones, so the human eye can discriminate color more readily. As Sach's work shows, however, in-brain structures also affect color cognition. This means that the eye may send a signal showing many colors, but the brain's cognitive abilties are key in the overall perception of color, and Sach's work shows that a damaged brain may not "perceive" colors in the same way as an undamaged brain, regardless of the occular neuro-structure.
In summary, a dog sees in 2 colors verus a human's 3 (and a parrot's 4), but perceives low light conditions than humans.
Let me explain this two answers to you a bit more in detail.
Dogs can see colors
Dogs not only see in shades of gray but also can see distinct colors contrary to what most people belief. About one hundred years ago some scientific tests were made to find out more about the color vision of dogs. But these tests weren't that scientific as they thought and the researchers concluded only that color vision doesn't play a part in the daily life of a dog.
Only about 90 years later distinct researches have shown that dogs can perceive colors. Neitz, Geist and Jacobs researched in 1989 the color vision of domestic dogs and found the following facts:
This results were support by later researches of Jacobs with colleagues in 1993 and Miller and Murphy in 1995.
Dogs are colorblind
This directly leads us to the second question concerning the color blindness of dogs. Colorblind doesn't relate to not see any colors but describes the fact that you can't see the same color range as somebody with normal vision. Because of that any kind of color vision deficiency is called color blindness. Therefore dogs are colorblind because of their dichromatic color vision.
Colors dogs can't distinguish
Actually the color spectrum made up of wavelengths of light is the same to all of us. Only the perception of those colors can be quite different. As dogs only have two different color receptors in their eyes they have problems to distinguish certain colors:
The list is not completed and there are a lot of different shades which can't be differentiated if you are colorblind. And the conclusion is dogs can see colors but are at the same time colorblind.While Humans see the rainbow- ROYGBIV- Red orange yellow green blue indigo violetDogs actually see- RYYYBIV- red yellow yellow yellow blue inigo violetOrange, yellow and green look all the sameto a dogand BLUE- GREEN is seen as WHITE by a dogCheck this website: http://www.puplife.com/pages/how-dogs-see-color

No, dogs don't see in black and white, they see in color. However they do not have as big of a variety of colors as humans do. They see some colors like red and green and yellow and grey, etc., They also see colors in a different way we do. Almost like a color blind human compared to a human who sees colors normally. They see red or green just in a different way.
no not all animals see in black and white. this is a common mistake.
Many animals see in color, for example the birds and octopi, some see colors better than we do. Most mammals have poor color vision though, we humans are a notable exception.
Both dogs and cats have limited colour vision.
Research has found that dogs and cats have colour-sensitive cones in their eyes, but not as many as a human's. Studies have shown that dogs cannot differentiate between green, yellow, orange or red. However, dogs are able to differentiate between various shades of blue and violet. This means that they see in shades of yellow and blue primarily.
It is thought that purple, blue and green appear to be the strongest colors perceived by cats. It is a possibility that they are also able to see yellow also. Red, orange and brown colors appear to fall outside a cat's color range and are most likely seen as shades of grey or purple.
no. dogs can see black and white, but they can also see almost every colour besides green, orange or red.
Some animals which do not have three sets of receptors only two cannot see in full colour; this includes dogs.
I don't think so, My pom LOVED oranage, whenever she would see Orange she would go crazy.
YEs they do itS A PRoVen FaCT!<3
they see in black a white because that is how they are made
they are black and white because preditors from the bottom see white when they look up and a penguins belly is white. Then preditors from the top see black and penguins backs are BLACK
It depends on what your question is. Cats do not see only black and white, but they do see black and white, as well as other colors(though the colors are blurry :/)
Yes
Well, I'm referring to all terriers. But when you say silky they are brown and black most of the time. Most rarely they are white. Silky terriers are mixed in with a hint of Dachshunds, Cairn terriers, and Yorkshire terriers.
hahah pomeranions
Yes turtles see black in white
well,if you are looking at the glare on the black, you will see white. but if you are looking at the black, but not at the glare, then you will see black.
they see in black a white because that is how they are made
yes actually all dogs see black and white
No, All Animals DO NOT All See In Black And White.
they are black and white because preditors from the bottom see white when they look up and a penguins belly is white. Then preditors from the top see black and penguins backs are BLACK
White is lighter than the black and in the dark, black is camouflaged so white is easier to see.

they see in black and white
Black, grey and white.
because it needs the black and white to see what is under it !
