Do they need darkness to sleep? Do they sleep better in dark or light rooms? This article covers everything about how dogs sleep and how darkness affects their sleep. Let’s see how dogs like to sleep and the effect that darkness has on them.
While darkness is not technically necessary for dogs to sleep, they do have a much better quality of sleep in a dark room, just as we do. Dogs are generally comfortable in the dark.
Do Dogs Need Darkness to Sleep?
This question has two parts, whether or not it’s possible, and then whether they will receive better or worse sleep, depending on the light. Let’s go through both of them below
Does your dog need the dark to sleep? The technical answer is no, dogs do not NEED darkness to sleep, and it’s more than likely you have seen your dog fast asleep during the day many times. Dogs can sleep whenever they feel like it, day or night.
One other thing to remember is that dogs sleep much more than we do. The average amount of time we sleep is around 6-9 hours, but for our dogs, it can be 16 hours or more every day. This suggests they will inevitably sleep during the daytime.
Do Dogs Sleep Better in The Dark
Now we know that dogs don’t necessarily need darkness to sleep, the next question is if dogs sleep better with darkness, compared to when it’s light.
This question is a little harder to answer, and that’s because dogs come from wolves which are nocturnal animals, meaning they sleep in the day and are awake at night.
However, dogs have since come away from their wolf heritage and have been used by humans for thousands of years. From the earliest point that humans used dogs, they would have followed our schedule, and we sleep at night.
So this suggests that dogs do in fact now sleep better at night time when it’s dark. Here are some reasons to support this:
- There is less noise and stimuli at night time when it’s dark, meaning their brain can relax and their sleep will be deeper and typically longer. This is the same for us.
- Darkness and lack of light often produce a response that is calming and relaxing. It generally signals to the brain that it’s time to rest.
- Despite sleeping for many hours of the entire day, most of them will be at night. By spending a lot more time being awake, active, and expelling energy throughout the daytime, being asleep during the night time when it’s quiet and dark will be significantly easier
- Our dogs are usually in sync with us and our schedules, by now your dog will know that when it’s dark, we go to sleep, and they will naturally do the same.
With that being said, it is typical to see our dogs completely flat out on the floor midday, with their paws and face twitching, barking, growling, or even wagging their tails! It’s still possible they’re having a great sleep even when it’s not dark.

Are Dogs Afraid of The Dark?
It’s a question that many dog owners often wonder about, and it’s also what triggers us to feel guilty if our dog doesn’t have a light on. Are dogs afraid of the dark? it’s certainly common with humans, so is it possible for our fluffy friends too?
So can dogs actually be scared of the dark? Well it certainly can appear that they are, but this fear can usually be explained quite easily
1) Separation Anxiety
A lot of dogs suffer from separation anxiety, especially Huskies! This happens when their owner leaves them, and sometimes the anxiety can happen instantly, or gradually over the course of hours.
It just so happens that when it’s dark, it usually means we are going to bed and leaving our dogs downstairs or in a different part of the house. It can also mean we are leaving the house for the evening or night.
Due to this, dogs will often link darkness to being left alone, which can trigger separation anxiety, which may result in them crying, howling, and becoming nervous.
So technically, it’s not because of the darkness itself, it’s because they associate the dark with being left alone (usually).
2) Lack of vision
As it happens, dogs have a much better vision than us when it’s dark. The back of the eyes in your dog is structured differently from ours, and they are designed to let more light into the retina in low-light situations.
So, while you may think it’s pretty dark, if it’s not completely pitch black, your dog will be able to see a lot more than you think.
However, in pitch black situations, their vision is like ours, next to nothing. So in times like this, your dog could become anxious due to not being able to see. Being scared of the unknown is a natural feeling and we can certainly relate to that. Our dogs too!
Without vision, dogs feel less able to protect themselves and will naturally feel more vulnerable. If they can’t see, they will feel at higher risk of external threats, and while we aren’t often worried about this, our dogs are much closer to their “survival instincts” than we are.

Other signs that your dog is afraid of the dark
So how do I know if my dog is actually afraid of the dark?
The two points I mentioned above can explain a lot and most of the time, it’s down to those reasons. However, there are certain behaviors you can look for which will suggest that your dog is afraid of the dark, at any moment.
- When the lights dim down, or you turn off a light in another room, your dog comes to you or to where there is more light.
- When you are walking your dog in the evening and approach a darker road or alley, your dog will be hesitant to go there or they’ll try to turn back. They could even completely stop and wait for you to go in front.
- In areas of darkness, your dog has its tail between there legs with their ears back.
- You find your dog hiding in random parts of the room if the light is turned off. This indicates they are trying to seek protection to feel more secure.
Should You Leave Your Dog in The Dark?
Perhaps your dog isn’t particularly afraid of the dark, but does that mean you can leave them in the dark at night or when you leave the house?
This depends on your dog, and what they seem to be comfortable with. You should carefully observe your dog around the times you go to bed or leave the house, watch their behavior and see if they are acting relaxed or anxious.
Unless you watch your dog closely, you may assume they’re ok in the dark, when actually they’re demonstrating discreet behavior which says otherwise. Body language will be your best friend when the lights go down or off.
If your dog gives a negative response to darkness, it would be best to leave at least a dim light on. Of course, always think of safety first, make sure this will not be a fire hazard, and never leave a lamp or light in the reach of your dog.
If your dog is afraid of the dark, leaving a light on will help in some ways, and this is better than none! At least they have their vision and won’t feel completely isolated.
Understanding Separation Anxiety
Separation anxiety is really common in dogs and it can be extremely stressful for them, even to the point of causing depression.
This is a serious condition that you will need to address, and being left alone at night time could be one of the triggers.
As it gets dark in the evening or nighttime, your dog will know that this means you will be going to bed, and they start to become more anxious or nervous as the hour’s pass.
If your dog whines or cries when you leave them to go to sleep, don’t assume this is because it’s dark, it could be because they’re dealing with separation anxiety.
This is quite hard to overcome and is typically caused when dogs are left alone too much and too often.
Ways to Help Your Anxious Dog at Night
If your dog is anxious at night time or when you turn the lights off here are a few things you can do to make them feel more at ease.
1) Separation Training
Your dog’s ability to remain calm and feel secure when they are alone is undervalued. Separation training is a great place to start if your dog suffers from this kind of anxiety.
During the daytime, preferably when your dog is already in a calm moment, leave the room and shut the door, go to another room and wait a few minutes before returning to the room. Do this multiple times per day, eventually increasing the time you are gone. Keep doing this until you work up to 1 hour gone. This may take 4 or 5 weeks.
Why does this work? This works because you are very gradually building your dog’s confidence when they’re alone, without leaving them too much each time.
2) Exercise In The Evening
Different breeds require different amounts of exercise, but it’s a good idea to make their daily physical activity in the evening, this will at least burn some extra energy nearer to bedtime.
It will certainly help your dog sleep if they’re physically tired, this will in most cases push past a lot of the nerves, and they’ll fall asleep even if they typically get anxious around bedtime.
3) Give Them a Comforter
This works wonders, but I don’t mean to give your dog one of their normal teddy toys
In this case, it’s something from you, an old jumper or t-shirt that you’ve been wearing, and have not washed. This will keep the smell of you next to them at all times. This has been shown to significantly reduce the nerves of anxious puppies and dogs in many different test experiments.
So next time you go to bed, sacrifice one of your old unwashed t-shirts and tuck it up next to where your dog is laying. Make sure it’s not a valuable t-shirt, in case they decide to chew it!

Can Dogs See in Total Darkness?
It’s estimated that dogs can see up to 5 times better than we can in the dark. But what about complete darkness? well, no. Dogs will not be able to see if it’s pitch black, with absolutely no light source.
If there is a light source from somewhere, it’s likely they will be able to see to some extent.
Not only are dogs pupils bigger than ours, which means their eyes let in more light, they also have more light-sensitive cells, called rods. These rods work extremely well in low-light situations.
Dogs also have their lens located closer to their retina, which results in the “image” being brighter on the retina. This enables their vision to remain bright and clear even when it’s low light.
Should You Leave a Light on For a Puppy?
We haven’t mentioned puppies during this article yet, so let’s see how puppies deal with darkness, and whether or not you should leave a light on for a puppy.
Puppies are small and vulnerable, we always try to be careful with them and ensure they are feeling happy and safe, so when we go to sleep, will they get scared if we turn the light off? like the kids?
The first thing you can do is ask your breeder, they will be able to tell you the sleeping arrangements before you got your puppy home.
Remember that puppies will take time to adjust to the new environment and it’s natural for them to show some level of separation anxiety. So try to replicate how the breeder would have had the puppies sleep (minus the siblings and the mother!). You can try to create a similar environment. If the breeder kept the light on, you can do that too.
There’s not really a right or wrong answer and it depends on your puppy. Try having them sleep with a light on and then with it off. Whatever works best, is what you should do until they grow older.
If you move the puppy crate into your bedroom and place one of your old used t-shirts inside their crate. This may provide them enough comfort and security, that they are happy to sleep with the light off. It’s worth a try!
So now you know all about dogs and the dark. Hopefully, this helps you, help your fluffy friend at night.
Remember that it all comes down to your dog, and all dogs are different. It starts with careful observation of your dog’s behavior as night time approaches. Some dogs will make it obvious they’re getting nervous, and for others, it may be more tricky to identify.
It is ok to leave a dim night light on if it helps your dog. Just always remember safety and the potential for electrical or fire hazards.
