We love them and pet them but when we try to take pictures, their eyes become tiny torch-lights and our well known pets look very fierce and alien to us. Dogs, just like cats and horses, have the ability to see in the dark and when a light is flashed on their eyes in the dark it starts to glow bright. The gleam in the eyes of the dogs is a natural phenomenon. They are natural hunters and hunt at night. It might seem eerie or even scary to you but the burning eyes of your dogs are just normal. Science explains the glowing dog-eyes perfectly.
