Dogs have only two types of cones, compared with the three types in human eyes. Dogs do have significantly fewer cones than humans, though, so scientists estimate that they only see colors about 1/7th as vibrant as humans do. In humans, the central retina (macula) is 100% cones. We know this because humans have three types of photoreceptors in our eyes that transmit signals in the brain over color, while our furry friends have only two types of photoreceptors, which allow them to see differences in a certain range of colors. How dogs see. However, some animals see colors we cannot. In the Russian study, scientists trained dogs to get a treat when shown four different colored pieces of paper – dark and light yellow, and dark and light blue.

So if they showed colors that the dogs could not distinguish, they would fail at the task, but if they chose colors that the dogs could tell apart, the dogs would perform consistently well. In fact, color camouflage, one of nature's favorite survival mechanisms, depends on the ability of the predator to distinguish colors. As a result, dogs don’t distinguish as many colors as do people. For some time, many believed that canine vision was limited and that dogs were completely colorblind; however, a 1995 study published in the Journal of the American Veterinary Medical Association revealed that dog retinas possess many color-sensitive cones, and that dogs therefore can see in color.

Elsewhere, we’ve dealt with the myth that dogs age seven years for every human year, but there’s another popular misconception floating around. But because dogs only have two cones, their ability to see color is limited and comparable to a human with a red-green colorblindness, which is a result of being born with only two cones as well.

Dogs even have a reflective membrane on their eyes that help them to see better at night or in the dark. Or is there some other way they see. The colors they percieve are not at rich or as many as humans can see. Dogs, whose eyes are closer to the sides of their heads, can see a field of vision of about 240 degrees, depending on the breed.
