Are dogs color blinded?

Question

I want a true answer and tell me how you know.

Answer 1

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 differentiate red from green.

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

Here you go, a chart to show how dogs see compared to humans, and the article about how they know this> http://www.uwsp.edu/psych/dog/LA/DrP4.htm

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

They think that they are color blind but none of us know's for sure because we dont have the technology to get inside of a dog's body

Answer 4

I have only heard that the dogs with different color eyes (one blue one brown) are color blind. Not too sure how true it is.

Answer 5

Yes, they are. Academically approved in 1989 (see link below).

Colorblind doesn't mean they can't see any colors at all but have some problems in distinguishing certain colors. They have approximately the same vision as a red-green colorblind person.

Answer 6

NO, dogs are NOT color blind! They see some colors as gray though. See link below.

Answer 8

no, there has been a new study that has proved that as a myth. The study says that although dogs can't see the full range of colors as we can, they can see shades of red, brown, and blue. Not just black and white.

Answer 9

Only some breeds. One breed even sees in blue and green, I know from a book about dogs.

Answer 10

They don't see color like humans.They see depth of various shades.Their eyes are made for hunting so color of prey isn't a necessity for them.Colors that are dark like red or green appear as shades of dark Grey or black.
