are dogs colorblind?

Question

ive heard dogs can see some color. can they really?

Answer 1

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:

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. 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.

I hope this helps to answer your question!

Answer 2

Dogs can see colour. Being colourblind doesnt mean they see in greyscale. A study undertaken at the university of california in 1990 conclused that dogs can see a similar range of colours to humans who suffer from red/green colourblindness (deuteranopia). This means they can destinguish only about 27 hues compared to the thousands of hues which people with normal colour vision can see.

Apparently dogs can see the colours at one end of the spectrum, like violet, indigo and blue, quite clearly. Bluey green appears as white to them, while all other colours are seen as shades of yellow. It is therefore very difficult for dogs to see the difference between green, yellow, orange and red, but very easy for them to differenciate between blue, orange and red.

It will probably help if you wear at least one dark colour or a dark/light combination when excersising or training your dog so that it can easily see your movement against the background.

Hope I helped a little!!

Answer 3

They can see shades of some colors like gray or blue, but they cannot see clearly. I dont know if you'd consider them colorblind.

Answer 4

New studies have shown that dogs do see in color, the only colors they have trouble seeing are greens and blues.

Answer 5

Yeas, dogs are colorblind./ It doesn't mean they see in black and white, but that they can not see certain parts of the color spectrum so colors may appear differently to them.

Answer 6

yes dogs are colorblind. they can only see color very lightly

Answer 7

Dogs cant see much color. They cant see as much color as humans do.

Answer 8

According to "The Dog Bible" (Edited by Kristin Mehus-Roe in 2005), dogs "live mostly in a world of grays with muted reds and greens (528)." **Their sense of smell is way better than humans'.

Answer 9

Not completely they can see some colors!!
