Is it true that dogs can only see in black and white?

Answer 1

yeah ...dogs are colour blind.. therefore can only c black and white...

Answer 2

Dogs aren't colorblind, but they do see colors
differently than we do. Dogs don't seem to be
able to see reds and greens very well, so their
world probably seems to be in shades of yellow
and blue. For a comparison of how you and a
dog see colors, go to this web site:

http://www.uwsp.edu/acad/psych/dog/dvision.htm

Press the link for "Dr. Ps training site", then
"General Topics", then "Vision". The first
article on acuity and color vision has the picture
you should look at, so you'll see what I'm talking
about.

Dogs don't see fine details as well as humans,
either. We usually see 20/20 or a little better,
but dogs see about 20/80. That's four times
blurrier! Dogs do see better at night, though,
and they also see moving things better than we
do. That may explain why your dog can spot
the moving ball that you throw in the woods. He
can tell exactly where it stopped moving. This
would come in handy for a dog in the wild
hunting squirrels and other small stuff. He'd be
able to tell where the squirrel was going, and if it
stopped, he could figure out exactly where. I
found some pictures of dog retinas too. The
retina is the back part of your eye that does the
seeing for your eye. There's one picture of a
normal eye, and three pictures of dog eyes with a
disease called progressive retinal atrophy.

Answer 3

dogs do not see in black and white, they have colour vision similar to red/green colour blind people. They only possess two of the three types of core (colour sensing cells in the retina). There are three types of cone: blue, green and yellow (often called red). Dogs only have blue and yellow and the yellow core detects yellow and red. When the yellow gets stimulated it signals either yellow or red, the yellow when mixed with signals from the blue receptors will detect green. Therefore dogs can not detect the difference between red and green.

Answer 4

All animals in the world, except humans and apes, see in black and white. The reason is that they dont have coloue receptors in their eyes so their brains dont identify colours. The same case is for dogs.

Answer 5

Iv'e heard that dogs can see some colors, and not only black and white.

Answer 6

Dogs have fewer color receptors in their eyes. This does not mean they only see black and white. What they see is just different from what we see.

Answer 7

While not strictly black and white, the distribution of cones and rods in the structure of their eyes make distinguishing colors difficult.
I kept my answer short and simple because I figured if you wanted a complete dissertation you'd look it up yourself. Some of these answerers need to keep that in mind. Damn they're long winded.

Answer 8

No, they see in color. Ive asked my dog to get the Red ball and she has 3 of the same only diffrent colors and she knows which ball I want.

Answer 9

So they say but how does my dog know my car is the red one and they also say they have a 3 second memory so how come we can teach them the things we do

Answer 10

Yes that is true.. something to do with the fact that their prey was usually camouflaged and the need to see in the dark more than they need to see colour.

Answer 11

Color blindness does not mean seeing only black and white. They do see color.
