So the dog can detect even faint light.
In darkness may both dogs and humans see nothing, but at dusk or in dim light is the dog with a reflective layer on the back of the eye wall superior to us again. This is also the reason why dogs eyes when illuminated by headlights in the dark so reflect. Due to the not so strong ausgepräkten muscles of dog eyes to the human eye, hence the sight of the dog's eye is weaker. The dogs eyes are farther apart like us humans, resulting in the dogs to a peripheral generally, far from improving eyesight. The differences of the peripheral vision also depends on the breed. This peripheral vision may e.g. lie with a Pekingnesen to 5-10 times and in a typical Terrier around the 20-30 fold.
