Do Dogs have Color Vision?

Veterinarians used to believe that dogs saw only in black and white, but recent studies suggest that they actually do have some color vision—but it’s not as bright as a human’s. As it turns out, dogs have only 20% of their ability to see color that humans do.

Dogs , as of yet cannot read an eye chart, behavioral tests suggest that dogs see in shades of yellow and blue and lack the ability to see the range of colors from green to red. In other words, dogs see the colors of the world as basically yellow, blue, and gray.

One amusing fact is that the most popular colors for dog toys today are red or safety orange. The problem, of course, is that red is difficult for dogs to see and may appear to them as a very dark brownish gray or even black. So if your dog runs right past the toy that you tossed, he may not be stubborn. He’s probably just having a hard time discriminating it from the green grass of your lawn.  Schedule An Appointment! http://www.genbook.com/bookings/slot/reservation/30150274
