Have you ever wondered if your four-legged friends see the hot pink or brown shade of the new toy you bought them?
People on TikTok are using a dog-watching filter to answer this question. With the accent filter, animals see the world in shades of blue, yellow and gray - the only colors your dog can perceive.
But is that really how your furry friends see the world?
Dogs possess two types of color-seeing receptors in their retinas. Dogs have only 1/10 the concentration of color perception compared to humans. Dogs see only two colors: blue and yellow, as well as any approximate shades of these colors. The rest of their world appears in gray or gloomy shades.
Dogs have a hard time distinguishing a red or green ball that you may have thrown to them to play with, but they use other senses to spot the ball, from smell to movement, shape and the way light is reflected.
The sense of smell is also important in dogs' perception, which is 10,000 to 100,000 times more powerful than that of a human. Humans have about five million olfactory receptors, while dogs have up to one billion.
When it comes to buying toys for your four-legged friends, you don't always have to choose the two colors they can see: yellow and blue. You can also buy toys in other colors to enrich the game with your pet.
