![]() ![]() ![]() In most dog breeds dark eyes are preferred and selected for and lighter eyes are tolerated if not avoidable. In many cases, their eyes instead look whitish or icy blue.Ī specific eye color is a characteristic trait of many dog breeds and is often part of the breed standard. ![]() Since blue light is scattered back outside into the open air more easily than other wavelengths this gives the impression of the eye being blue.Ī partial or complete lack of pigment creates eye colors like blue, pale green or yellowish-green hazel eyes. Even dogs with absolutely no pigment in their iris (yes, even albinos) rarely have a completely translucent membrane. When there is no pigment to absorb some of the light entering the iris all the light gets randomly and diffusely scattered by different fibers and particles. Structural color is caused by light interacting with eye tissue instead of pigment molecules. So if the color of the iris is not caused by eumelanin pigment color but instead due to a lack of pigmentation we call this a structural color. You see, there is no green or blue pigment type in dogs since eumelanin can only be (diluted) black or brown. And of course, there are many possible combinations in between. This creates many different nuances and a huge spectrum of dog eye colors.ĭogs with black pigment and a high pigment density have very dark eyes while dogs with lighter pigment (brown, blue, lilac) and a very low pigment density will have very pale eye colors. The more eumelanin there is and the denser it is packed the darker the eye will look. Yellow eyes can have the color of honey or amber or be very pale with a greenish hue. Brown eyes can be light brown, orangey-brown, dark brown or almost black. Btw, a dog’s pupil just like ours always has a round shape.īut not only the color but also the color intensity varies from dog to dog. Behind the pupil we find the lens that directs light to the retina at the back of the eye. The iris reacts to different amounts of light and can contract or dilate to control the diameter of the pupil, a hole located in the center of the iris. The iris tissue contains not only pigment granules but also a mesh of fibers, blood vessels, nerves. The iris is the colored membrane surrounding the pupil of the eye. When we talk about all the naturally occurring dog eye colors we usually refer to the color of a dog’s iris. ![]()
