Answer 1

Nope not true at all.

Answer 2

Sight:

Humans have the ability to see all the colors of the electromagnetic spectrum, while the dog does not. It is thought that humans rely on color to find and identify food. Dogs have prey which are usually camouflaged, so they do not have to rely much on visual cues to find food. Because dogs have more rods in their retinas than humans, their ability to see in dim light is much greater. They are also better able to detect motion. Dogs see in colors of yellows, blues, and grays. The color red would appear yellow to a dog, and a green object would look white. Dogs have better lateral vision than humans.

Cats also have more rods than cones in the retina. Like dogs, they can see better in dim light and are far superior at detecting motion than that of humans. These are important traits for hunting. The pupil in the cat is elliptical rather than round, which allows more light to enter the eye. The tapetum is located in the back of the eye, and reflects light a second time—this is how cats are able to see well in almost complete darkness. Cats can see in the purple, blue, green, and yellow range and can see more shades of gray than humans can.

Answer 3

Dogs have two color receptors and are called "dichromats".
So they are partially color blind, but they can see more than simply black and white.

I am trying to find links that show you the colors that dogs do see.

Bozema found a really good site, and I've listed below one of their other pages with more information on canine vision that's interesting and compares human to canine vision.

Answer 4

There have been TONS of studies to show if dog can see color.

I believe(from what I've heard) that dogs see shades of grays, blues. But the can not see reds.

Very good question!

Answer 5

No, they have the rods and cones in their eyes for black and white AND color vision. Maybe their vision isn't as clear as ours, but they see color just fine.

Answer 10

dogs see "VIBYYYR" (Violet, Indigo, Blue, Yellow, Yellow, Yellow, and Red). The colors Green, Yellow, and Orange all look alike to dogs; but look different from Red and different from the various Blues and Purples. Dogs are very good at telling different shades of VIB apart. Finally, Blue-Green looks White to dogs.
