do dogs really see in black and white?and how do u no?

Answer 1

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.
Dogs and cats have vision with a very limited color spectrum. Red and blue can be distinguished but red and green appear similar.
Animals rely on contrast and movement to identify objects. This type of normal vision is restored following cataract surgery with implantation of a replacement lens.

Answer 2

I don't know.... always wondered how anyone other than the dog knew for sure! I do know that dogs see some colors better than others, but it might be because of contrast rather than the actual color. I do know that my dogs could not see pieces of watermelon (which they liked) when they were on the lawn, which was green. They always found them by scent.
