When taking pictures of people, you often get "red-eye" using a flash, as
this reflects the retinal wall's blood into the shot.

But why are doggy eyes green?

Can any of you vet techs research this one?

I asked my vet about this once. His explaination was there is a special
reflective layer in the back of many animals eyes called the tapetum
which enhances nocturnal vision.

Yep. When I became aware that Chloe, my late Old English Sheepdog,
was showing signs of difficulty seeing in low light conditions, I
took her to an opthalmologist. It turned out that she had almost
no tapetum in her right eye - he thought she was quite fascinating.
I asked him what might've caused it, and he told me there was no
way to know. It could've been genetic, but as she was spayed and
from unknown parentage there was no way to know for sure.

Anyway, once I became aware that this was the case, it was very
obvious to me that her right eye didn't glow and the left one did.
