Here's a breakdown of dog vision:
* Blue and Yellow: Dogs can distinguish between shades of blue and yellow, but they can't see red, green, or orange.
* Shades of Gray: Dogs can see shades of gray, but they won't see the full spectrum of colors we do.
* Motion: Dogs have excellent motion detection, allowing them to see things moving even in low light.
* Light Sensitivity: Dogs are more sensitive to light than humans, which is why they often seem to see better in the dark.
Why dogs see the world differently:
Dogs have fewer cones (light-sensitive cells) in their eyes than humans. These cones are responsible for color perception. Humans have three types of cones, while dogs only have two. This limited number of cones is why dogs can't see the full spectrum of colors.
Interesting fact:
While dogs can't see red, they are more sensitive to certain shades of yellow than humans. This is why many dog toys are bright yellow!
