Question

Dogs can only see black and white

Comments

this claim would be inaccurate because dogs do not see only in black and white. While their color vision is limited compared to humans, they can see shades of blue and yellow. Their vision is similar to a person with red-green color blindness. If you're discussing dog vision, it's important to present the facts accurately to avoid spreading misinformation.

This claim is false, Dogs may only have two types of cones which detect only blue and yellow colors (compared to three in humans), but this allows them to have more rods in their retinas than people do, so they can see better in dim light.  Dogs see shades of browns, yellows, greys and blues. However it is true that colors are more muted for dogs than what we see.

This has proven to be false I believe by many reputable sources, dogs have been proven able to see multiple colors just not to the same degree. Due to differences in the eyes not being able to see color helps dogs in different ways as they can see better in the dark. Leaving a source to prove your claim next would help or looking more into the subject as a whole.

This is a great and straightforward fact-check. The initial statement is reviewed and then the true fact is stated with an attached source that seems to be reliable. One way that this fact-check could be improved is with additional sources and possible quotes pulled from those sources.

---

It seems that the claim was untrue and misleading. It was proven wrong by many sources before, and it originated from an author of DogWeek Magazine. Great fact check!

Answer 1

This claim is false. 

The American Kennel Club (AKC) explains the origin of this false understanding. The AKC states, "The notion that dogs see only in shades of black and white has been attributed to Will Judy, a lifelong dog fancier, writer, and past publisher of Dog Week magazine...'It’s likely that all the external world appears to them as varying highlights of black and gray,' Judy wrote in his 1937 manual, “Training the Dog.”" 

Dogs do have more limited color vision than humans. The site Dogs Naturally has an article explaining this. It states, "Your dog’s eyes...only have two cones – blue and yellow. This is called dichromatic vision, and it means that while your dog can still see color, his perception of it is muted compared to a human. The biggest difference is that dogs can’t process red light, which can make it hard for them to distinguish certain colors." These certain colors dogs are unable to process are red and green, and colors involving them.

Your argument is articulated very well! Your introduction clarifying where this original claim started is very supportive, as well as your thorough explanation following up. I did note, though, that neither of the last two sources had any references or any evidence to particularly support their claims. The ACK link specifically discloses at the end that they are simply providing general information and should not be used for medical advice. The magazine also lacks any specific references verifying it's information.

---

Great job citing multiple reputable sources, especially the American Kennel Club! One way to strengthen this even further would be to clarify whether other studies have confirmed the same conclusion about dogs' dichromatic vision. Are there any recent scientific studies or veterinary sources that reinforce this claim?

---

This is a great fact check, it is clear that the original claim did not do enough prior research, and you show great knowledge in this topic, which leads to a great fact check to start with along with credible resources.

---

I really liked your fact check to the claim "Dogs can only see black and white." You did very well in using quotes from your source as well as analyzing the specific colors that dogs can see. You even gave the origin of where this false claim came from as well as debunking the myth that dogs see black and white. Most of your sources are relatively recent as well showing how recent the research was done.

---

This fact check was very helpful. It is clear that you did plenty of research before answering, which I appreciate. You also have a solid amount of sources which is also nice. the quoted parts are thought out and clearly relate to your claim.

Answer 2

It is a common misconception that dogs can only see in black and white. The way color is perceived is derived from the number of cones and rods in the eye. The difference between the human and dog eye is that "dogs have have more rods than cones in their retina, whereas people have more cones" (Meyers). Dogs have dichromatic vision. Because of this, dogs are capable of also seeing yellow and blue colors, yet they cannot see red an green. Thus, dogs can see more colors than black and white (greyish tones).

I really enjoyed how you talked about it was a misconception. I liked how you brought up the difference between a human and a dog.

---

Thanks for the info, amazing!

---

Good, concise information.

---

I like how you not only state your claim, but you also provide scientific information about the eyes of dogs.

---

This is a good fact-check that gets right to the point. It is clear and concise and wastes no time getting the main idea explained.

---

I appreciate your attention to detail and outlining why it was a misconception and why it is considered fact now.

---

I like how concise and to the point your answer is. I also think the source you chose is a good one because of the specificity of the field they study in.

---

You were descriptive with how you described the colors, but I would suggest adding another source to make your claim stronger.

Answer 3

According to the link below, cats and dogs have two types of cones that respond to blue and green light. This suggests they have adequate color vision.

This is a decent article, it provides a great explanation to back up your answer. However, there's no clear author or apparent publish date on the article, which means this information could potentially be quite outdated and inaccurate. I'd suggest looking for articles within a couple years and that have an author who you can look up and verify their credibility. Information like that goes a long way in backing up your claims and makes it that much more valuable.

---

Well put, but the article provided Cites "scientists" as the source of this being a myth. I don't think this is very convincing source, something more convincing would be an article that provides a source, or even better the actual original research paper.

---

I appreciate the link to the article speaking more on this topic. Although, it would have been helpful to see more information in your post on this topic before I delved into the article.

Answer 4

In the past people believed that dogs could see in black and white but that has been proven to be a myth. In fact according to Adelaine Vet, dogs and cats are colourblind " humans use three cones – red, blue and green. However cats and dogs only have blue and green cones. This means they have a much more muted perception of colour, which is akin to colour blindness in humans". Some way or form dogs can't see in full color.

Comments

I agree with your claim, but I don't think your source provides enough information to prove it to be true or false. It just describes that dogs have different rods and cons than humans, but not why this is the case.

Answer 5

it is wrong dogs can see colors, according to AdelaideVet:

"It was once thought that animals, including cats and dogs, could only see in black and white. However, scientists have proven this to be a myth"

Comments

I like that your source is from a veterinarian site but I think it would be more reliable if the statements had sources that supported the statements they put in response to the myths.

Answer 6

While scientists previously believed that animals were only able to see in black in white this has been proven wrong recently, making this statement false. Dogs cannot see color as much as humans as humans use three cones and dogs use two, however they still have a perception of color.

Answer 7

<!--StartFragment-->

New research and conclusions about dogs show that while dogs may not be able to see as much as humans do, dogs can still see a mass proportion of colors as we can. It is a misconception that dogs can only see in black and white. According to AKC, examinations of the canine eye structure reveal that due to the nature of evolution and function, there are some basic differences in the design between dogs and humans. "Dogs developed their senses as nocturnal hunters," and due to this aspect of evolution, dogs eyes' are therefore adapted to see well in the dark and catch movement, which creates a larger lens and corneal surface and reflective membrane in dogs. Low-light vision in the retina is also improved, and the retina is the main focus of this color perception idea. Cones in the retina work and control color perception, and there are more rods than cones in a dogs eye. Because of this the wavelength color spectrum of dogs is differently perceived which causes them to see and miss certain colors.

To add on, according to PSU, dogs see minimal in color but do in fact see in color. In easier words, dogs see as a colorblind human would. The concept of the structure of the retina was also emphasized in this article.

What is AKC? You mention it as your source but it is not clear what that is.

---

The AKC stands for the American Kennel Club. As stated on their about page, "For more than 130 years, the American Kennel Club has been the country’s leading authority on all things dogs." They are probably most well-known for their detailed information pages on dog breeds, but they have loads of information on health, responsible ownership, etc. Thus, a reliable source for the question of dogs' eyesight.

Answer 8

According to Adelaide Vet, a vet clinic in Australia, it's a myth that cats and dogs can only see black and white. Scientists have proven that the "perception of color is determined by the presence of cells in the eye called cone photoreceptors." Cats and dogs have two kinds of these cones that can see blue and green light. 

Because of this, cats and dogs are color-blind, but only to some color, not all. Humans have all three cones to see blue, green, and red light, but since cats and dogs only have two, they cannot see red light. Their eyes have a muted perception of red so they are colour-blind to that color. "For example, behavioural tests in dogs suggest that they can distinguish  red from blue, but often confuse red and green. Similarly, they often perceive green as grey.

Your explanation is clear and precise. The website that you found is amazing for people to learn more about pets and how to take care of them. The website is reliable, and you provided lots of explanations to the question, which helps reader to understand why the answer is false. Nice Work.

---

That's a solid post! You mention a clear source, the common misconception, and current evidence. I appreciate that you provide a clear explanation and a quote from your source. One thing exclusive to your post is the explanation of how dog's eyes view colors differently from humans. For example, you mentioned that dogs seen green as gray. This really helps the reader understand from a dog's point of view. I do think that adding another source would strengthen your claim. I also recommend restating the claim to clarify. Overall, this fact-check is a well-developed.

Answer 9

It has been proven to be a myth that dogs can only see black and white.

According to "American Kennel Club"  dogs develop their senses as nocturnal hunters, tracking and catching their food at night. Their eyes are adapted to see well in the dark and catch movement.

Comments

Can you provide a hyperlink to your source?

Answer 10

This is false. Dogs can actually see color, just not as good as humans. Dogs have poor vision and can only see blue and yellow. According to American Kennel Club, “Dogs have more rods than cones in their retina, whereas people have more cones, and this apparently makes the difference in color perception.”

https://www.akc.org/expert-advice/health/can-dogs-see-color/

This a great response. You used a reputable website to find out that dogs can actually see color. You also quoted American Kennel Club which further strengthened your claim that this statement was false.
