German Shepherds are known for their exceptional night vision. Their eyes contain a reflective layer called the tapetum lucidum, which helps them see better in low light conditions.
This layer reflects any available light back onto the retina, allowing the dog to see more clearly. It's like having a built-in flashlight that helps them navigate in the dark.
German Shepherds' eyes are also more sensitive to light than humans, with a higher concentration of rod cells. Rod cells are responsible for detecting movement and changes in light levels.

Understanding Dog Vision
Dogs have a unique visual system that allows them to see in the dark. Their eyes are designed to function well in low-light conditions, thanks to a higher number of light-sensitive rods in the retina.
In fact, dogs have 20/75 vision, which is significantly different from humans who have 20/20 vision. This means that dogs can see objects clearly at a distance of 20 feet, but with a limited sharpness compared to humans.
Dogs are crepuscular, meaning they are active primarily at twilight, and their eyes have adapted to function in this environment. They can spot movement in the dim light, which helps them track and catch their dinner or breakfast.
Here are the key factors that determine a dog's vision:
- Visual perspective
- Field of view
- Depth perception
- Sharpness of vision (Dogs typically have 20/75 vision.)
- Perception of color and form
- Ability to perceive light and motion
Their ability to see in the dark is also enhanced by the tapetum lucidum, a reflective layer behind the retina that acts as a mirror, reflecting light and giving the retina another chance to register it. This is a unique feature of the canine eye that humans don't have.
Why Do Dogs' Eyes Glow in the Dark?
Dogs' eyes can glow in the dark due to the tapetum lucidum, a reflective layer in the back of the eye that acts as a mirror, reflecting light and giving the retina another chance to register it. This is why you might see a greenish-yellow glow when light hits a dog's eyes at night.
A fresh viewpoint: Do German Shepherds Have Blue Eyes
The tapetum can reflect a range of colors, including green, blue, orange, and yellow, and its color can change over the first three months of life. Some dogs, especially those with blue eyes, don't have a tapetum, so their eyes might appear red in photos instead.
Dogs' eyes often glow more brightly when light hits the tapetum, making them appear eerie in low-light conditions. This is especially noticeable in photos taken at night or with a flash.

What German Shepherds See at Night
German Shepherds, like their wild ancestors, have an advantage when it comes to seeing in the dark. They can spot movement in dim light, thanks to their crepuscular nature.
Their visual perspective allows them to see in low light conditions, and their field of view is likely similar to that of humans. In fact, dogs typically have a wider field of view than humans, which helps them detect movement from the sides.
Their depth perception is also important for navigating in the dark, allowing them to judge distances and avoid obstacles. Dogs typically have 20/75 vision, which means they can see objects clearly at 20 feet that a human with normal vision can see at 75 feet.
In terms of light and motion detection, German Shepherds are well-equipped to handle the dark. Their ability to perceive light and motion helps them track and catch prey, even in low light conditions.
