I am assuming that you mean that your dog's eyes are of a pale colour.
Normally a dog's eyes glow back green due to the presence of a reflective layer behind the retina called the tapetum. This layer is often absent in pale coloured eyes, so that light reflects back red through the blood vessels in the retina.

Hi stvkfmn,

There's nothing wrong, so relax! The light is reflecting off the back of the retina, that's all. No harm, no foul.
