Question

Dogs can only see black and white

Comments

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!

This claim is seemingly incorrect, as there’s no source to back up the claim.

I really like how this explains the myth in a simple, easy to understand way! The comparison to red/green color blindness makes it super clear, and the AKC citation is a nice touch it makes the info feel really credible. Great job!

The claim that dogs can only see black and white is false. Dogs can see shades of blue and yellow, but have difficulty distinguishing between red and green.

The claim that "Dogs can only see black and white" has long been a popular and widley shared belief. However, recent scientific research has proved that this myth is incorrect. Supporting the idea that dogs do see color, however, not in the way that humans do. I discovered that dogs have only 20% of the cells that humans have, which are for detecting color. (Pedigree, 2025). Because of the lack of cells that dogs have, their vision is more limited, only seeing yellow and blue shades. Many media sources altered the assumption that dogs only see in black and white, without prven evidence.However, research specifically in veterinary studies has provided evidence that while dogs do not see the full spectrum of colors like humans, they are not colorblind in the way previously thought, only susceptible to certain shades.

Answer 1

This claim is false. It is a myth that dogs can only see shades of grey, but it is true that dogs have a smaller range of color vision than humans do. Will Judy hypothesized that dogs only saw in black and white in 1937. The American Kennel Club released a well-researched article about the history behind the myth and the science behind the actual color range that dogs have and it appears to be hues of blues and yellows as opposed to the idea that it is a range of greys.

    The claim that dogs cant see color is false, The link above is a website that explains how the common belief that dogs only see in black and white is a myth. Dogs actually can see some colors, though their vision is different from humans. They have two types of color-detecting cones instead of three, allowing them to see blues and yellows clearly, while reds and greens appear as gray or brown. Their eyes are also better adapted for detecting movement and seeing in low light. Because of this, toys and training tools in blue or yellow are easier for dogs to see than those that are red or orange.

   The link above explains is similar to my first link and goes into depth on the myth that animals only see in black and white has been debunked by scientific studies. Color perception in animals, including cats and dogs, depends on cells in the eye called cone photoreceptors. Dogs and cats have two types of cone cells sensitive to blue and green light, whereas humans have three, red, blue and green. Because of this, cats and dogs have a limited color spectrum they can’t differentiate reds and oranges as well as humans can, often confusing red and green. Most animals do have some level of colour vision, and only very few examples such as a certain fish species are confirmed to see purely in black and white.
