I just bought the book "How Dogs Think" by bestselling author, psychologist, and world-renowned expert on dog behavior and training, Dr. Stanley Coren. It gives an interesting look at the way dogs interpret their world and their owners, how they solve problems, learn, and take in new information. Dr. Coren lets you see through a dog's eyes, hear through his ears, and even sense the world through a dog's nose and more. I'm only on Chapter 3, but here's what I learned about a Dog's Vision. Take Note!
* Dogs typically have 20/75 vision. (It means people see something clearly at 75 feet, dogs only at 20 feet).
* Dogs sense motion better than people (i.e. spotting a squirrel a great distance)
* Dogs see better than people in dim lighting, due to larger pupils
* Dogs have better peripheral vision than people, 'cause their eyes are more toward the side of their heads... so they see the world in a Panoramic View
* Dogs see Colors! Mostly Blues and Yellows.
* Dogs can't see Red. They see it as Dark Grey.
* Dogs can't see the color difference between electric orange and green (so bright orange balls aren't easy for dogs to find in grass).
HOW PEOPLE SEE RAINBOW COLORS: Violet, Blue, Blue Green, Green, Yellow, Orange, Red
HOW DOGS SEE RAINBOW COLORS: Dark Blue, Light Blue, Grey, Light Yellow, Dark Yellow, Dark Grey.
WHY? People have 3 "cones" in their eyes that enable them to see Blues, Greens and Oranges. (color-blind people like me are missing one cone. I'm missing the green one). Dogs have 2 "cones" in their eyes for Blue and Yellow. (PHOTO: Dolly's pretty green eye)
