Can Dogs See in the Dark? 

Do you ever wonder if your dog can see in the dark? No need to worry! Healthy dogs can see in the dark better than humans. In fact, the secret to dog night vision if all in the sight receptors that distinguish between daylight and dark.

You may be wondering how dog night vision works. Dogs do not have night vision in the sense that they can see when it’s very dark and there is no light. The cornea, pupil, leans, and retina help construct a dog’s eye. The secret of a dog’s night vision that allows them to see better in the dark compared to humans is the large amount of light-sensitive rods found in the retina that collect light. The dog’s rod-dominant retina collects this light and using a thin tissue behind the retina called the tapetum lucidum amplifies the light back to the lens which focuses on what the dog is looking at.

Dogs rely on the following features for night vision:

  • Visual acuity
  • Motion detection
  • Light sensitivity
  • Visual perspective
  • Depth perception
  • Color perception
  • Visual field of view

One of the most interesting facts about dog eyesight is that their eyes glow green in the dark when light shines on them because it’s reflecting off the tapetum lucidum, which humans do not have. The good thing about the position of the eyes on a dog’s head is that it gives them a wider peripheral field of vision, which ranges between 240 to 270 degrees, depending on the breed! So, yes, dogs can see in the dark – much better than humans can!
