do animals see colours, like dogs?

Answer 1

How dogs see

Dogs can see in much dimmer light than humans. This is because the central portion of a dog's retina is composed primarily of rod cells that "see" in shades of gray while human central retinas have primarily cone cells that perceive color. The rods need much less light to function than cones do.

Dogs can detect motion better than humans can.

Dogs can see flickering light better than humans. The only significance to this appears to be that dogs may see television as a series of moving frames rather than as a continuous scene.

Dogs do not have the ability to focus as well on the shape of objects (their visual acuity is lower). An object a human can see clearly may appear to be blurred to a dog looking at it from the same distance. A rough estimate is that dogs have about 20/75 vision. This means that they can see at 20 feet what a normal human could see clearly at 75 feet.

Dogs are said to have dichromatic vision -- they can see only part of the range of colors in the visual spectrum of light wavelengths. Humans have trichomatic vision, meaning that they can see the whole sprectrum. Dogs probably lack the ability to see the range of colors from green to red. This means that they see in shades of yellow and blue primarily, if the theory is correct. Since it is impossible to ask them, it is not possible to say that they see these colors in the same hues that a human would. Whether or not the ability to see some color is important to dogs or not is hard to say.

Also consider the perspective that dogs see the world from. A dog with its eyes about 12 inches off the ground certainly sees the world a different way than a human with eyes about 48 inches off the ground like many 5th graders.

As humans we tend to think of dog's visual capabilities as inferior to ours. It is different but it may suit their needs better than possessing accurate color vision would.

First things first

Wow LiliRose that was really informative.... thanks .......and I used to think I knew everything about a dog.

The problem of distance vision is correct. Also Dogs and many animals may be having more of rods than cone cells but they might not be colour blind entirely.

What about birds and chameleon and peacock why do they have colours? In fact what about all other dogs except the black & white ones like Dalmatian or tibetian Apsoe.

My physics is weak but isn't colour determined by the frequency of light. And doesn't frequency of light have a continuous spectrum.

If that be the case who gets to decide that from what freq to what freq is Red and what is Green and what is blue.

Just because we humans see a certain band of freqency as red it doesn't have to be the same for other species.

Bats and dolphins percieve more through sound. There may be species which see in the infra red or the ultra violet region of the light spectrum.

Colours are thus relative term ..........a colour blind person would probably see the world a little differently. Life is strange......

Answer 4

it extremely is not abuse. Too many females and adult adult males think of that any variety of correction is abuse. some females and adult adult males might somewhat that a canines be euthanized then be gifted with adversives. No it extremely is usually a ordinary technique of training. I had a do gooder turn me into the humane society thinking that my canines became as quickly as carrying a pinch collar at a community park. The humane society in simple terms laughed thinking they had an determining what canines training entailed. i'm afraid the at present the attitude could be different. although, i'm not going to alter all my techniques in simple terms to maintain the do gooders delighted. i'm unlikely to flow into training technique or no remember if or not you may properly be incorrect following Cesar's procedures. that's not what I surely have examine into your question. If this technique is working for you, proceed making use of it as long as you may properly be trustworthy doing so. Alpha rolls can placed the owner in a real intense project while used on aggressive, bossy doggies. i've got the scars to instruct this.

Answer 5

No. Animal are colour blind. For more details on dogs visit www.dogsvets.net

Answer 6

no none of the animals including a bull and excluding a monkey don't have a colour sense
they are totally colour blind
they can only see black,white and grey colours

Answer 7

No, dog see thing in gray colour. That's why they're able to see in the dark.

Answer 8

Dogs do not see color. Black and white is what they see. I dont know about any other animal but dogs for sure do not.

Answer 9

yes,few animals can sense red colour...and so on..

Answer 10

No, dogs see in shades of gray, black and white.
