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.
