| What makes diff dogs eye glow a certain color? My friends new chihuahua's eye glow firey red in all photographs no matter what angle( I call them satan eyes ). CHloes eyes glow green in some photos. Pennys eyes just completely reflect back light. And I dont get much of a glare with Tink. So what scientifically or medically makes them reflect different colors? I am so curious now. I know its not just based on the breed either because my chihuahua doesnt have "satan eyes" like my friends chi.

| I read on here a little while ago that the color that reflects in pictures can tell you what the yorkies coat colors will be when full grown. I don't know what exactly causes the different colors but I remember the thread was pretty interesting. |

| I don't know the scientific reason for the color the eyes glow. I do know that in yorkies, the red glow usually indicates a cottony coat and the green eyes indicate a silky coat. It would be interesting to find out why this is. |

| The only breed I know about is the Yorkie green glow which reflects their coat type. Regarding the other breeds I don't really know. Possibly a lot of it is the camera flash, but who knows??? It is indeed a mystery though isn't it??

| I want to know too. I know that green in a yorkie indicates silk coat, but other breeds??? I'd really like to know. Here's my mom's maltese Tucker, his eyes are always red, even if you take him outside at night, they flash red at you and he is very silky coated for a maltese. My golden is always green in pictures. |

| So far I think the eye indicating the coat type is just a myth. Chloe eyes are always green in photos and she is not a silky coat so she defies that myth. And as a lover of science I think there has to be a fascinating reason why dog eyes reflect different colors. I plan to get to the bottom of this

| . Why Do Animal Eyes Glow at Night? FAQ From Marilyn Haddrill, Your Guide to Vision. FREE Newsletter. Sign Up Now! A. Most of us have seen that eerie green, white, or orange glow of animal eyes caught in headlights on a dark night. But what causes that glow? And why don’t human eyes have it? If you’ve ever wondered why you never seem able to obtain a decent flash photo of your cat without that same annoying glow captured on film, you can blame it all on an extra reflective structure found within the eyes of certain animals. “Bright Carpet” Tapetum lucidum, Latin for “bright carpet,” is an extra layer of mirror-like, reflective tissue found behind the animal eye’s inner back area ( retina) where light-sensitive cells are found and images are processed. The tapetum lucidum makes the very best use of even the dimmest of light sources by reflecting unabsorbed light back into the retina. This enhances the animal’s ability to see in the dark. Nocturnal Vision This reflective layer of the eye is more common in nocturnal animals adapted for night hunting, or who need to depend on keen night vision for survival. Certain underwater creatures such as dolphins also have the eye structure, enabling them to see in low lighting of deep water. What Causes Different Glowing Colors in Animal Eyes? Depending on the different types of pigment found in the animal eye, you might see different colors shining back at you. The green glow is typical of deer, dogs, and cats, whereas a crocodile has a chilling red “eye shine.” But Don’t Human Eyes Glow Red, Too? We’ve probably all experienced the dreaded “red eye” of flash photography, when images of our loved ones (especially those with larger pupils) end up looking like apparitions from a horror flick. “Red eye” in humans caused by the camera’s flash originates from reflections from blood vessels and red tissue in the retina, and not from the tapetum lucidum found in the far more reflective animal eyes. A cat needs only one-sixth the light that a human would require to see, according to Cornell University. FAQ Index |

| Ok this is what I found out about the eye color thing. From ask a scientist at Cornell University. Tapetum causes dogs' eyes to reflect in different colors Why do some dogs eyes reflect red instead of yellow and does this have anything to do with their coat type? Ask your own question! The colored reflection from the eyes of dogs comes from a layer of tissue at the back of the eye (the choroid) that contains blood vessels, brown pigment cells, and, in most dogs, a shiny cell layer (the tapetum) covering mostly the upper half. This tapetum probably improves animals’ vision at night. It may be yellow, green, blue, orange, or variations in between those colors. So the tapetum is the usual source of a dog’s eye reflection. Some dogs, though, have very small tapeta or none at all and they show a very dull reflection or none at all. In other dogs, especially dogs with certain hair coat colors (liver, orange-brown) or with blue eyes (irises), very little pigment is present in the back of the eye and the blood vessels that are normally hidden by this pigment are visible and make the reflection bright red.
