Are dogs and cats really colorblind?
Recently, dog vision filters have been all the rage on TikTok. Users can select this filter, aim their phone cameras at their surroundings, and see the world the way their dog sees it.
But then I started watching some of the scores of TikTok dog vision filter videos, and I began to understand why some people are so affected by their dog’s literally pallid view of life. This one of Kyle Scott’s Buddy the Coliie — playing fetch with a drained-of-color ball in a drained-of-color field — is particularly affecting, especially since Scott captioned it: “I’m never blaming Buddy for losing his ball ever again.
“Dogs possess only two types of cones and can only discern blue and yellow,” they write. In other words, dogs can see shades of blue, yellow and gray, but they can’t see green, red or orange. So, dogs are similar to humans who have red-green colorblindness, according to PetMD. This is the most common type of colorblindness.
“Dogs are more near-sighted than we are,” explains Buzhardt of the VCA Animal Hospital. That means objects in the distance appear blurry to them. She also says they’re less cognizant of changes in brightness.
