are dogs color blind?

Answer 1

BOTH answers are correct, depending on context.

When a man is tested in the military, or for a commercial driving license, the chart tests for color blindness. If he is deemed color blind, it means he can't see red and green, but only sees them as shades of brown..that is the human condition known as color blind.
However, dogs do not differentiate between red and green, so by human standards, yes, they ARE color blind.

But, some people think that the term means that color blindness is seeing only in black and white...dogs DO see other than black and white and shades of gray..so, they do see color.
They see yellow, blue, and tans/browns very well, and some shades of purple..but they don't defferentiate red from green, but see these colors as shades of brown.

So, do they see color? YES
Are they color blind by human terms? YES
Do they only see black and white? NO

Answer 2

Yes dogs ARE color blind, they see in two colors instead of three exactly the same as some color blind people. The difference between a dogs eyes and ours is that a dog has fewer cones (collect color) and more rods (collect light) so a dog sees colors about like a color blind person, and sees at night about like a person using night vision goggles.

We see "VIBGYOR" (Violet, Indigo, Blue, Green, Yellow, Orange, Red)
dogs see "VIBYYYR" (Violet, Indigo, Blue, Yellow, Yellow, Yellow, and Red). The colors Green, Yellow, and Orange all look alike to dogs

Answer 3

Dog see colors the way a colored blind person sees colors. They can see much more shades of grey than humans can and determine more levels of brightness. Dogs can see some colors

Answer 4

yes .dogs see only in black and white.

Dogs were thought to be dichromats and thus, by human standards, color blind. New research is now being explored that suggests that dogs may actually see some color, but not to the extent that humans do; color may serve as a subliminal signal helping to distinguish overlapping objects from each other, rather than a distinct feature that the dog can directly determine. It has also been suggested that dogs see in varieties of purple/violet and yellow shades. Because the lenses of dogs' eyes are flatter than humans', they cannot see as much detail; on the other hand, their eyes are more sensitive to light and motion than humans' eyes. Some breeds, particularly the best sighthounds, have a field of vision up to 270° (compared to 180° for humans), although broad-headed breeds with their eyes set forward have a much narrower field of vision, as low as 180°

Answer 5

Oh boy, not a correct answer so far. Dogs do see colors but in a limited range:

Answer 6

My daughter told me that people can see color because their eyes are color and dogs can see black and white only because their eyes are black. Not bad for a 4 year old! :o)

Answer 7

yes Dogs are color blind all they see is black and white

Answer 8

Yes they are color blind.

Answer 9

They say they can only see on a gray-scale, but I am sure mine do see some colors, so i am sure it's just a limited amount of colors for them.

Answer 10

No. The only color dogs cant see is red.
