Dogs have several anatomical advantages that allow them to see better in low light conditions than humans. These include:

  • A tapetum lucidum: This is a layer of tissue at the back of the eye that reflects light back through the retina, giving the cells there a second chance to absorb it. This helps dogs see better in low light conditions.
  • More rods: Rods are cells in the retina that are sensitive to light. Dogs have more rods than humans, which gives them better night vision.
  • Wider field of view: Dogs have a wider field of view than humans, which helps them see more of their surroundings.

However, dogs do have some disadvantages in terms of vision compared to humans. These include:

  • Less color vision: Dogs can see some colors, but not as many as humans. They are most sensitive to blue and yellow, and they have difficulty seeing red and green.
  • Less depth perception: Dogs have less depth perception than humans. This is because their eyes are set farther apart, which gives them a wider field of view, but it also makes it harder for them to judge distances.
  • Less visual acuity: Dogs have less visual acuity than humans. This means that they can’t see fine details as well as humans.

Overall, dogs have better night vision than humans, but they have some disadvantages in terms of color vision, depth perception, and visual acuity.

How Can You Help Your Dog See Better at Night?

There are a few things you can do to help your dog see better at night. These include:

  • Make sure your dog has plenty of light: If you’re going to be walking your dog at night, make sure there is plenty of light around. You can use a flashlight or headlamp to help your dog see.
  • Avoid walking your dog in unfamiliar areas: If you’re going to be walking your dog in an unfamiliar area, try to do it during the day so your dog can get a good look around. This will help them to learn their surroundings and be more comfortable walking there at night.
