Should You Leave Your Dog In the Dark?

By Tamara McRill

Know that feeling when pulling into the driveway at night, flush with shopping success, only to be slammed with guilt because you didn’t leave any lights on for your dog? Yeah, me too. After I run inside to pet the dogs, I always wonder: Are dogs okay with being left in the dark?

Not just that, but is it also safe for dogs to be in the dark? Can they see?

Generally Better Night Vision

Obviously, that can depend on your dog, but it turns out it may also depend on just how dark it is in the house. Dogs do have better night vision than people in very low light situations. This is because they have a special structure in the back of their eyes that reflects more light to the retina.

So your furry housemate is going to make out more looking out the window at night than you will, but that is due to their eyes being able to better utilize the small quantities of light available. Say, from other lit up windows, streetlights or the moon.

Pitch Dark Navigation

When it comes to pitch black darkness, though, dogs can see about as well as we can. Which is pretty much nothing. Wait, but your dog can navigate the living room with absolutely no light? I believe you, but chances are it is because of his ability to quickly memorize the layout of the room.

For example: We had a town-wide blackout for five nighttime hours this summer. The dogs walked around just fine, until I moved some pop boxes in the kitchen. Dusty tripped over them on his way through, because he couldn’t see them and they weren’t there the last time he was in the kitchen.

So your dog can probably navigate your home in the dark, just from memory. It’s even easier for them if a streetlight or other light source is shining in the window. Same goes for them being outside at night.
