What do dogs actually see through their eyes?? Is it colour or black and white?

Answer 1

From personal experience i would definatly say Colour, although how much colour they can see i dont know.

Our dog loves the colour blue - when given the choice of toys he always goes for blue - and it is not because of the smell as they are brand new ones (also once we held a treat and a toy in one hand, and just a toy in the other and he still went for the blue, treat-less toy)

There is no proof of dogs only seeing in black and white, this is just what people have been led to believe as they do not know any better. There are scientific reasearch papers that have concluded that they do see in colour and many vets, trainers and owners have read these and made up their own minds based on the evidence.

Answer 2

A dog can see shades of colour

A dog's vision is generally inferior to that of man
but it can see colour, static shapes and does not perceive
detail. However, dogs are very sensitive to moving
objects and can see a hand waving up to a mile
away . The predominance of rod receptors allows the dog to see much better than humans do at night. Dogs are very sensitive to sudden or unusual movement, an asset made use of in guide dogs, retrievers and hunting dogs. The panoramic field of vision is 250-270° but binocular vision varies greatly in different breeds according to how far their eyes are set in the front of their head, e.g., the Pekinese or Bull Terrier have binocular vision about 85°, or a Greyhound
about 75°, man has about 140°.

Furthermore, the extent to which a dog has peripheral
vision depends on its skull shape. A visual streak in the
retina is required for peripheral vision, but this has disappeared in short-skulled breeds such as the pug.
Although it has previously been thought that dogs
are ‘colour blind’, recent studies have shown that under
bright light dogs are capable of detecting wavelengths
within the blue and yellow portion of the light spectrum
and are therefore dichromatic. However, they are incapable
of distinguishing reds and oranges as they have
only a few of the cones sensitive to the red/orange
wavelengths.

The visual colour spectrum of dogs can be seen in
two forms: violet and blue violet, which is seen as blue
and greenish yellow; and yellow or red, which is seen as
yellow. Therefore, dogs are red-green colour blind and
are also better at differentiating between shades of grey
than humans.

Night vision is assisted by a reflective layer of cells,
known as the tapetum lucidum, which is located behind
the retina and reflects light back through the retina.
The absolute threshold for the detection of light is
about threefold lower than humans, allowing the dog to
be three times as capable of detecting low light intensities.
Puppies experience difficulty in identifying objects
until 4 months of age when visual maturity is attained.

Hope this helps.

Answer 3

Although it is commonly believed that dogs and cats see only in black and white, recent evidence suggests that animals may have some degree of useful color vision. The perception of color is determined by the presence of cone photoreceptors within the retina. These cone cells function in bright light conditions and comprise approximately 20% of the photoreceptors in the central retina of the dog. In humans, the central retina (macula) is 100% cones. Behavioral tests in dogs suggest that they can distinguish red and blue colors but often confuse green and red.

Answer 4

actually they do see some color just not as much as a human can. They have a limited amount of rods and cones but they do see color, but it has a very different hue and tone. Its believed that dogs with blue eyes only see black and white but not to sure. But the common belief that dogs are color blind is completly false.

Answer 5

The parts of the retina that process colour are called cones. The B&W cells are called rods. The rods are much better at distinguishing very low light sources like stars. Dogs eyes contain no cones (as far as I know) so that is how we know that their vision in B&W (like cats). But they would have very good night vision as a result.

Generally, colour vision only evolves in animals that have fruit in their diets, cause they need to be able to distinguish between ripe and unripe fruit.

Answer 6

A dog does not see in black and white only. That is an urban legend; however, it does see in a variety of mutated colors. It doesn't see in the full color spectrum that we see, but has its own type of color spectrum.
