Question

Why do dogs have that reflective glow in their eyes?

Answer 1

it's how the light is reflecting from the back of the eye

Answer 2

i think it has something to do with how they see differently from us and how different their eyes are from ours. like how they are supposed to see in black and white. i think. :)  

Answer 3

It is the retina reflecting the light back at you. The eyes don't actually glow. You know how your or anybodies eyes look when photographed caught by a flash camera? That is the same thing.

Answer 4

Dogs have a layer of reflective cells in the back of the eyeball called the tapetum.  It's usually green/silver in color, and it reflects green/silver when strong light hits it.  In dogs with blue eyes the tapetum  may not have any pigment and it just reflects red, the color of the capillaries in the eye.   The tapetum allows dogs to see in much lower light than we can.  It bounces what light is available and concentrates it for the rods to see.  Cats have tapetums also!  Theirs is usually more of a yellowish color.

Answer 5

It's to mess with our minds to give in to their begging...lol

Answer 6

Doesn't it have something to do with helping them see better at night?

Here, maybe this article will help, I haven't read it but it sounds informational.

Answer 7

In my dog, he was taken off of his mother's milk at 5 weeks old (she had an infection) and I was told that the blueish/silverish glaze over his eyes is a result of the lack of milk during the important first 8 weeks. However, a glaze in the eyes of older dogs is usually an indicator of Glaucoma and should be checked by the vet.
