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

Answer 1

No it isn't. They have a limited range of colours, which you can mimic by looking through orange glasses. It gives excellent long range and night vision, great for hunting. It also makes them more aware of movement, again great for spotting prey.
You have cells called rods and cones in the retina of your eye, dogs have fewer of the type that can see colour.

Answer 2

According to http://www.sciencenet.org.uk/ , 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.

I couldn't find any scientific proof or background for this though.



hope i helped (:

Answer 3

No. Dogs can not only see in color, but very similar to the way humans see. In daylight, they have depth perception problems, which is why if youve ever dropped something for your dog and he didnt see it, you have to point to it. At night, they see with incredible detail, like the Hubble telescope. people are very fast to say the have inferior eyesight, but thats not true, thats just human nature to want to rule!

Answer 4

As you no longer need a dog licence in this country all dogs are now allowed to see in colour.

Answer 5

I think they can see a certain amount of colour but they only see in two dimension

Answer 6

Compared to people, dogs have...

Better motion vision

Better night vision

Less developed color vision

Less developed close-up vision

Answer 7

No
They see in shades, mostly grey but can differentiate colours

Answer 8

yes, it's true, no colour what so ever but they recognize you in other ways (smelletc), there are of course other opinions on the subject though

Answer 9

I don,t know either but how do those who profess to know perform the test. Ask them to point out red!

Answer 10

I think so, that's why my dogs have all the Laurel and Hardy films!
