What a cutie! We get "red-eye" from the reflection off of our blood vessels in the retina. Dogs have a special layer of cells at the back of the eye, though, that reflect light back to the retina in order to help them see in low light, so that's the reflection you're seeing. I think it must be the same effect when my cats' eyes glow green when you shine a bit of light at them in a dark room. http://europuppyblog.com/item/2008/01/why-do-dog-s-eyes-glow-in-the-dark
