Understanding Dog Vision
You may often find yourself wondering what the world looks like through your dog’s eyes. As a caregiver to your furry friend, it’s natural to want to understand their perceptions better. Contrary to popular belief, dogs do see in color, just not the same way we humans do.
Scientists believe that dogs see the world in a dichromatic color scheme, which is a fancy way of saying they see two primary colors: blue and yellow. This is quite different from human vision, which is trichromatic, allowing us to perceive three primary colors: red, blue, and green.
The Science Behind Dog Vision
To truly comprehend how your dog sees the world, you need to understand a little about the science of vision. The retina, a layer at the back of the eye, contains two types of cells responsible for detecting light: rods and cones.
- Rods are more sensitive to light and dark changes, shape and movement and tell us more about function.
- Cones are responsible for detecting color.
Humans have more cone cells than dogs, which is why we see a wider spectrum of colors.
Colors Dogs See Best
While dogs may not appreciate the entire rainbow as we do, they do have a certain color preference. Evidence suggests that dogs see best in shades of blue and yellow.
| Human Color | Dog Perception |
|---|---|
| Red | Dark Gray |
| Orange | Grayish Brown |
| Yellow | Light Yellow |
| Green | Gray |
| Blue | Blue |
| Violet | Light Blue |
