BOTH THE CILIARY AND IRIDIAL PORTIONS OF THE INSENSITIVE RETINA HAVE TWO LAYERS OF CELLS. THE CILIARY PORTION HAS ONE PIGMENTED LAYER (THE outerLAYER) AND ONE NON PIGMENTED LAYER (THE inner LAYER). The innerLAYER OF CELLS ARE PIGMENTED IN THE IRIDIAL PART OF THE INSENSITIVE RETINA.

Pigmented layer of epithelial cells: with pigment without pigment
Tapetum lucidum = non-pigmented CCT under pigmented epithelium layer
Little to No Tapetum lucidum Choroid
Tapetum lucidum = reflects image from back of the eye in animals that can see better in the dark that can humans
Tapetum lucidum is located at the back of the eye, but not on the sides
Given the tapetum lucidum is located at the back of the eye, the dog (animal) must be looking directly at you for you to see the reflection.
