What makes diff dogs eye glow a certain color?

[Harley'sMom]

I found this article on the net and thought I would share it with you, pretty well explains why dogs eyes glow different colors.


Why does your dog's eyes shine in such a creepy way in photos? The answer is, for the same reasons our eyes come out red – because of the way the flash is reflected off the back of our eyes. The difference in color of the reflection is due to the structure of the eye. In a person, flash photography makes our eyes appear devilish red. This is because the flash reflects off the a blood vessel rich layer behind the retina.

In dogs (and many other animals), the retina has a reflective layer behind it called the tapetum lucidum. This layer acts like a mirror, reflecting light at the back of their eyes. The reflective layer is what helps dogs and cats see better at night. Light is reflected outward, giving the dog's retina a second chance to absorb to absorb the rays .

Light that is not absorbed exits the eye, appearing as the "eyeshine" seen in photos, from headlights, flashlights, etc. This ability comes at a price, as dogs cannot see detail as well as humans (they are more attuned to seeing motion).

Note: Some dogs lack pigment in their tapetum lucidum. In these individuals their “eyeshine” is red, as it is in humans.

I also wondered about this because some pictures of tilly are always green and she is a silky but sami's eyes are sometimes red then green? so maybe his coat would be silky cotton or is it because of the time of day you take the picture? lighting? anybody? I know he is not a mix! he is 100% mamma's Boy akc
