Your other friend isn’t a pet, but a member of the family.
Research shows that 76% of 20-38 year olds own a pet, and about of that, nearly half treat their pets like their own baby and spoil naturally for their own pleasure. Or to put it another way, this generation loves their pets more than ever. As a pet owner, ensuring your pet is safe is a top priority. So, do you leave lights on for your dog?

Should I Leave a light on for my Dog when I go out?

Some owners also leave lights on for their dogs to see in the dark, but dogs have much better low-light vision than humans. That's because they have a section of their eye known as the "tapetum" that causes them to reflect light more. It provides the retina with one more opportunity to absorb light.
But being able to see really well now in the low light doesn’t mean they will stargaze successfully through the pitch black. Your dog may have bad eye vision if there are no lights in your house at night. They do have a very keen sense of smell and hearing, so they won’t be as helpless as we humans are when there’s no light. They might still be able to navigate the home, even if they don’t see well.

Do dogs need a light on at night?
There’s no hard-and-fast answer to this question, and it depends a lot on your own pet. For instance, some dogs may want the reassurance of night or dim lights, particularly if they are in a compound of stress or foreignness; some elderly dogs need a night light to help recognize their surroundings in the dark. Other things to note are the advantages of lights at night for additional safety. You know your pet best so experiment with different lighting conditions to see which one you think he reacts best to.
But most people do not care to leave lights lit, as it is dangerous and consumes a lot of electricity. A great solution is to place a light with a photocell feature so it can shine again when it's dark, keeping your pup happy, while also saving your money
