If you’re wondering whether your furry friend prefers to catch some z’s in a dark or bright room, you’re not alone. Many dog owners have this same question as they try to make their pups as comfortable as possible.
If you’re short on time, here’s a quick answer to your question: Most dogs do seem to prefer sleeping in darker areas. This likely traces back to their early evolution when darker dens and caves provided safety and security while sleeping.
The Origin of Dogs’ Preference for Darkness
Instincts from Wild Wolf Ancestors
Dogs inherited many behaviors from their distant ancestors, the wolves. As pack animals, wolves feel most secure when surrounded by their family group. They often sleep together in dens or other sheltered areas to stay safe from predators.
This preference for snuggling up with loved ones in dark, cozy spaces seems to be wired into dogs’ genetics (an ancestral instinct that still influences their behavior).
In the wild, darkness also provides camouflage and protection for wolves. Under cover of night, wolf packs can move about freely without being spotted by rivals or attacked. So resting in dimly lit areas helps wild canines avoid harmful threats.
Our domestic dogs retain these ancient wolf-like tendencies. Though comfy snoozing on the living room rug, they subconsciously associate the dark with safety thanks to countless generations of wilderness-forging forebears.
For today’s pampered pups, the dangers faced by primeval wolves may be a distant memory. But the instinct to seek refuge in the shadows remains deeply ingrained.
Feeling Protected and Secure
Most dogs sleep more soundly when shrouded in darkness. The coziness of a den-like environment makes insecure pups feel more protected and relaxed. Some easily spooked dogs may even bark or growl when lights are on at bedtime.
Turning off bright overhead bulbs and using a soft nightlight instead can help timid dogs wind down. The enveloping gloom allows them to sleep without worrying about any unexpected scary sights. It taps into their natural preference for dim, sheltered spots that set ancient wolf minds at ease.
Heavy-duty light blockers like blackout curtains also reinforce the den-like safety of a snoozing dog’s surroundings. By making bedrooms extra dark and womb-like, total light blockage promotes supreme snuggler comfort.
Scientists found that in nearly total darkness, dogs slept over 2 hours more per day than those exposed to dim light (reference). So for champion canine catnappers, pitch black rooms are the ultimate sleep-inducing sanctuary!
Signs Your Dog Wants to Sleep in the Dark
Seeking Out Dark Corners and Closets
If your furry friend starts nosing around dark, enclosed spaces like corners, crates, or closets, it likely means they are seeking a nice dim area to catch some Zzz’s. According to the American Kennel Club, dogs feel more relaxed and comfortable when they have a den-like environment to sleep in.
So if Rover is suddenly way more interested than usual in exploring those shadowy nooks around your home, it’s a clear sign they want some shuteye in a darkened hiding spot.
Restlessness in Bright Rooms
Can’t seem to get your pooch to settle down for a nap lately? Take a look at where you’ve situated their dog bed. Well-lit rooms can prevent a dog from getting proper daytime rest. If your home is flooded with bright natural light or you have all the lamps on, try dimming the lights and see if your pup conks out.
Light sensitivity is common in many dog breeds. Excess light exposure can overstimulate their sharp vision and make it challenging to fall and stay asleep. So if your four-legged friend seems antsy, agitated, or keeps repositioning themselves in a bright space, it likely means lights out would be their preference.
Relaxation in Dimmer Areas
Pay attention to where your dog chooses to plop down when it’s time for their midday or evening snooze. More often than not, it will be in a darker part of the room away from any glaring light sources.
In fact, a 2015 study revealed over three-quarters of surveyed dogs elected to sleep in dim locations. So if you notice your pup relaxing in shadier spots in the house, it’s a clear indicator they favor dozing off in darkness.
Making their preferred sleeping area a bit darker may lead to longer, better quality sleep for your fur baby.
Making a Comfortable Dark Sleep Area
Location Considerations
When selecting a location for your dog’s bed in a dark room, consider choosing a quiet spot away from drafts and high traffic areas. Dogs tend to prefer sleeping in areas that make them feel safe and free from disturbances. An out-of-the way corner, or next to a wall, are often good choices.
Additionally, be mindful of temperature. Avoid places near heating/cooling vents, windows, or doors leading outside. Fluctuations in temperature can disrupt sleep. Ideally, identify a place with stable comfortable room temperature if possible.
Here are some ideal location options to consider:
- A corner of the bedroom
- Next to a wall in a hallway
- In a closet or small enclosed room
- Under furniture like tables or desks
Bedding Considerations
Proper bedding can further enhance your dog’s comfort and sleep quality in a dark environment. Pay special attention to material, cushioning, and containment.
Material: Avoid crinkly plastic beds. Instead choose soft, textured fabrics like flannel, fleece, or microsuede. These materials hold heat, feel good on paws and bodies, and absorb sound for undisturbed rest.Cushioning: Prioritize beds with thick cushioning and memory foam bases. This prevents pressure points and distributes weight evenly for dogs sleeping in the same position for hours.Containment: Raised sides create a cozy, den-like enclosure which dogs naturally seek. Products like donut cuddler beds or covered caves supply this security.
By pairing a secluded, peaceful location with the right bedding materials, you can create an comforting oasis perfect for your dog to sleep in the dark.
When to Provide Some Light
Puppies Learning the Ropes
Puppies are still getting used to the world around them, so a bit of light can provide reassurance and help them learn the layout of their environment. According to the ASPCA, puppies feel most secure sleeping near littermates initially.
As they grow more independent, a night light lets them explore and find their way without bumping into furniture or getting disoriented in the dark. It also helps with housetraining, allowing them to see their way to the right spot.
So it’s perfectly normal for puppies under 6 months old to prefer a little light at bedtime.
Senior Dogs With Changing Needs
As dogs enter their golden years, their needs change. Senior dogs often experience cognitive decline, disrupted sleep patterns, and anxiety. So a low nightlight can help make them more relaxed and comfortable.
According to SeniorTailWaggers.com, exposure to light and dark helps regulate circadian rhythms. Disrupted circadian rhythms in elderly dogs can lead to restlessness at night. A dim light provides visual cues to help senior dogs orient themselves and settle down.
Leaving a hall or bathroom light on or placing a nightlight in their sleeping area gives aging dogs the comfort of being able to see while still allowing darkness for sounder sleep.
Anxious Dogs Who Need Reassurance
Some dogs are naturally prone to anxiety and fear, especially at night. A University of Helsinki study found that noise phobias and separation anxiety are common causes of nighttime restlessness in dogs. Sudden noises or being left alone can trigger panic.
The study showed that providing a quiet, reassuring presence helped dogs relax and sleep better. For anxious dogs scared of the dark, a calm night light delivers that soothing presence. It also allows them to scan for threats and see that all is well.
While not a cure for anxiety disorders, a low-level light source can make these sensitive dogs feel safe enough to settle in for the night.
Signs Your Dog Prefers Some Light
When it comes to their sleeping environment, some dogs prefer a dark and quiet space while others feel more relaxed with a little bit of light. Certain breeds tend to be more prone to anxiety in the dark.
Additionally, nervous behaviors when the lights go out or vision issues in elderly dogs are hints that your pup would sleep better with some illumination.
Breeds Prone to Anxiety
Anxious behaviors like panting, pacing, whining and even destructive chewing often start when the lights go off. Breeds genetically inclined toward neurotic disorders like separation anxiety are more likely to demonstrate these behaviors at night according to the American Kennel Club.
These include herding breeds like Border Collies and Australian Shepherds. Terriers also tend to be high strung without proper stimulation. Leaving a dim night light on or curtains cracked can prevent an anxious outburst after you turn the lights out.
Nervous Behaviors in the Dark
Dogs that display nervous body language such as lip licking, yawning, shaking and restless movements when the room goes dark often feel more at ease with some light. Crack open the closet door to emit some illumination from the hallway.
Use a low wattage bulb nightlight to provide a glow instead of total darkness. Notice if your pooch relaxes and falls asleep more easily with this simple accommodation.
Older Dogs With Failing Vision
As dogs get up there in age, their vision starts to decline much like it does in humans. Limited eyesight makes total darkness even more challenging for senior pups. Leaving a hall light on outside the room or using motion sensor plug-in night lights that automatically turn on when your dog gets up and moves around can be tremendously helpful.
That little bit of light helps old dogs see well enough to get around safely and confidently.
| Age | Vision Signs |
| 7 years + | Developing cataracts, corneal changes, some vision loss |
| 10 years + | Often detached retinas, significantly decreased vision |
As the chart shows, senior dogs undergo major vision deterioration. Illuminating their way with night lights provides confidence and safety.
Conclusion
While most canines will seek out darkened sleeping quarters if given the choice, every dog has unique preferences you’ll want to pay attention to. By understanding your pup’s personality and needs, you can make small tweaks to their sleeping space that will keep them cozy all night long.
A happy dog snoozing nearby is every owner’s dream!
