does anyone have proof that dogs can only see in black and white?

Question

it really saddens me to think that dogs can't see in color!

serious answers only please

Answer 1

no

Answer 2

I read somewhere that dogs are red-green colorblind (they can see blue and yellow, though, and shades of gray for the other colors.) Or maybe it was Triumph the Insult Comic Dog. Anyway, they should be able to see some colors.

You could try an experiment with different colors--red, blue, yellow, and green, for example. Like, have the dog pick a certain color of toy or block or something to get a treat. Say, red block-->treat. Put out a red block, a green block, and a yellow block. The dog will know the yellow block is wrong, but it can't tell the difference between red and green, so it won't be able to pick the right block like if the blocks were, say, yellow, blue, and black. Then give the dog a nice treat for participating in your experiment.

My dog seems insanely happy even in the dark, so maybe she's OK with not seeing all the colors in the spectrum. They have excellent hearing and smelling senses to make up for not seeing colors, and their eyesight is keen even if it's not colorful.

Answer 3

I"m not sure who told you that they only see in black and white but that is not true. Colour blind even in humans does not mean you can only see black and white either.

Dog and cats have less of a colour variation then we do and that has been determined by examining their cones and rods in their eyes. The biggest difference and what newer research is suggesting is that perception is actually a bigger issue. Have you ever seen a dog or cat attack themselves in a mirror? Well, they can't tell that the other creature isn't really because they do see same depth perception or 3d like we do. They also have tougher times distinguishing different patterns.

I don't think that this mystery will every be truly solved but just rest assured that cats and dogs see more the black and white.

Answer 4

this might help some I hope this was a class room experiment
The experiment consisted of a small dog and two lights. One light was red, "good" light, a blue light, "bad". Treats were used each time the dog walked towards the red light and nudged it. The dog was not given a treat for approaching the blue. After 10 successful attempts towards the red light the treat was faded out. The dog approached the red light 3 out of 5 attempts without the treats. This gave indicated dogs can tell the difference in the two lights. One variable was taken into consideration. Was the dog reacting to the sense of smell of food on the red light or was she really distinguishing between the two lights even when their positions were switched?

Answer 5

Yes, Researcher have compiled a 2 years poll in which a 10,000 dogs were asked to bark if they see black or white on a series of photographs, and if they can see a color in a particular photo they were to say which color it was. The poll concluded that all 10,000 dogs questioned barked and none of which were able to identify a single color.

Figures have the been compiled by the Gallup Poll Organization (Education and Research Division), 1959 poll # XCH459382.

Answer 6

Dogs and cats have vision with a very limited color spectrum. Red and blue can be distinguished but red and green appear similar.



Humans, primates, insects, fish, some reptiles, and most birds can see color well.
though dogs and cats do not see colors WELL this is due to the lace of 'cones" but this does NOT mean however that they can not see ANY colors.. The perception of color is determined by the presence of cone photoreceptors within the retina. These cone cells function in bright light conditions and comprise approximately 20% of the photoreceptors in the central retina of the dog. In humans, the central retina (macula) is 100% cones. Behavioral tests in dogs suggest that they can distinguish red and blue colors but often confuse green and red.

Answer 7

This guy walks into a bar.

there's a handwritten sign behind the bar that says "talking dog for sale"

guy asks the bartender - is that for real? bartender says, yep, dude lives around the corner.

guy walks around the corner. finds an old rundown redneck house, scraggly dude in a wifebeater t shirt sitting on the porch, drinkin a beer, smokin a cig.

guy says, you the dude with the talking dog for sale? dude says, yep, he's in back, go have a look.

guy walks back, sees this perfect, gorgeous, well-kept looking golden retriever. and a momma retriever, lying on her side nursing a bunch of young puppies.

dog looks at the guy, says "you here about the sign?"

guy takes a minute to recover his pulse rate, says, yeah, I guess I just didn't believe it.

dog says, well, it is unusual. but somehow I was born this way, and when I was just a pup my owner realized it, and told some friends, and the next thing I now I'm at a secret CIA lab and they're training me to be a spy. Man you wouldn't believe how many times i've saved this country from horrible war and terrorist attacks, because I can go almost anywhere and listen to anybody, and they don't care cause I'm just a dog.

but, I'm tired of all the stress and the travel and the bs of working for the government, so I took a pension and retired here with my wife n kids. that guy out front isnt' my owner, he's from the CIA to watch out over me. anyway, since I'm on pension, they're gonna cut me loose and I have to find my own place. you interested?

Guy thinks for a minute, says, let me go talk to the guy out front. Dog says, ok, I'll be here.

Guy goes out front, looks at the dude, says, so you're CIA huh?
How much you want for the dog?

Dude says, ten bucks.

Guy says, ten bucks????


Dude laughs, says, aw you didn't believe all that stuff he told you didja? that dog's so full of ****, he never did any of that stuff.

Answer 8

I really don't know but I think they can see in color because some dogs are able to tell the difference between something especially if they never saw it before I know my dog can

Answer 9

My german shepherds can tell the difference from sealed beverage cans whether its Mountain Dew, Budweiser or Busch beer can. They'll grab the Bud cans everytime, puncture them and drink the beer if I don't get them away first!

And my pomeranian goes nuts when I take his towel out of the dryer as opposed to an identical one that is a different color--one is tan and one is more cream so it's not like there's a major shade difference, one looks a bit more faded than the other.

Answer 10

This is copied from veterinaryvision.com:
"Although it is commonly believed that dogs and cats see only in black and white, recent evidence suggests that animals may have some degree of useful color vision. The perception of color is determined by the presence of cone photoreceptors within the retina. These cone cells function in bright light conditions and comprise approximately 20% of the photoreceptors in the central retina of the dog. In humans, the central retina (macula) is 100% cones. Behavioral tests in dogs suggest that they can distinguish red and blue colors but often confuse green and red."

Answer 11

Well some time back scientists did studies and found out dogs only see in black and white. There is your proof.
