Is It True That Dogs Only See In Black And White?

It's a bit of a misconception that dogs can only see in black and white. In fact research suggests that they do have some colour vision similar to red/green colour blind people. Dogs only have two of the three types of colour sensing cells in their retina. There are three types of these cells; blue, green and yellow (often referred to as red). Dogs only have blue and yellow and it is the yellow cells that detect both yellow and red. This means that a dog can't detect between something that is green and something that is red.

However, don't feel too sorry for your little canine friend. Although he cannot distinguish between green and red, and his focus vision is poorer than that of a humans, his night time vision is far superior to ours. Thanks to a reflective system at the back of the eye, dogs see objects in the dark illuminated far better than we ever could.

Dogs can't go to the eye doctor and read the chart so a lot of what we are told about what dogs see is speculation. Dog trainers swear that dogs can be trained to pick up things by color. So who really knows. I do know that dogs have other senses that are more developed than ours such as smell, hearing and ESP. Yes, ESP. Try thinking about feeding your dog and visually imaging it in your mind and see if your dog will go to his bowl.
