You may have heard this old-wives tale: dogs only see in black-and-white.
In fact, scientists say dogs can see some colors, namely shades of yellow, brown, gray and blue.
If you think this is basically “color-blind” by human standards, remember dogs have excellent vision and can out-see people in the dark.
It all comes down to differences between human and dog eyes. Human eyes have three “cones” (needed to see during the daytime and perceive colors) while dog eyes only have two. Human eyes have fewer “rods” (needed to see well at night) than dog eyes. So dogs can out-spy us in the dark.
Score one for people, one for pooches.
Which is “better”? That depends.
You want to paint a brilliant sunset? Human eyes. You want to see what is lurking in the forest at midnight? Stick with dog eyes.
Perhaps the best way to look at it is one isn’t superior than the other. Human eyes and dog eyes are just different ways to see the world.
Until next time,
Hugs and pug kisses,
Candy
