Puppies require a lot of sleep to grow and develop properly. They tend to fall asleep when it gets dark, due to their circadian rhythms, which act as an inner clock. While puppies can sleep during the day, their deep sleep cycles kick in when it's pitch black outside. A dark sleeping environment is one of the most important factors in getting a good night's sleep, as light can disrupt melatonin production and negatively impact sleep quality. However, puppies may refuse to enter a completely dark room, and some older dogs with poorer vision may become nervous or tense in the dark. In such cases, leaving a dim night light on can help them feel more secure.

What You'll Learn
Puppies sleep better in the dark as their bodies produce more melatonin
Puppies, like most animals, tend to fall asleep when it gets dark. This is due to their circadian rhythms, which act as an "inner clock" that controls their sleep/wake cycle. Deep sleep cycles kick in when it's pitch black outside, allowing for better sleep with fewer disturbances.
The darkness signals the puppy's brain to start producing melatonin, a hormone that promotes healthy sleep. Studies have shown that artificial light exposure before bedtime delays melatonin production and decreases its levels during sleep. Blue light, in particular, from screens such as TVs, smartphones, tablets, and computers, disrupts melatonin production the most. Thus, it is recommended to minimize screen time before bed and use red or low light to reduce melatonin disruption.
While dogs have better low-light vision than humans, they cannot see in complete darkness. However, leaving a light on at night for puppies may not be necessary. Turning off the lights can help signal to puppies that it is bedtime and aid in establishing a sleep routine.
As dogs age, their vision may deteriorate, and they may have increased difficulty seeing in the dark. In such cases, leaving a low light on can help older dogs feel more comfortable and navigate their surroundings without hurting themselves.

Older dogs may need a night light due to blurry vision
While puppies tend to fall asleep when it gets dark, this is not necessarily the case for older dogs. As dogs age, their vision deteriorates, and they may have increased difficulty seeing in the dark. This blurry vision can make them nervous or tense, and they may pace or sleep in unusual places that make them feel safer.
Older dogs may benefit from a night light due to their blurry vision. A low light may help them settle and feel more comfortable and protected. This is especially true if they have an eye condition, which can be more easily detected if noticed early. A dim light won't harm your dog and can make them feel more secure.
However, it is important to note that light can affect sleep for dogs, just as it does for people. A dark sleeping environment is one of the most essential factors in a good night's sleep. Bright light during the day and darkness at night are best to maintain natural melatonin levels. Studies have found that artificial light negatively affects learning and memory in multiple animal species, including dogs. Exposure to light during sleep cycles can decrease melatonin levels, which is associated with an increased risk of cancer.
Therefore, it is recommended to provide a dark sleeping environment for your dog at night. If your older dog struggles with blurry vision, a low light or night light may be beneficial, but it is not necessary to keep the light on all night. You can turn it off once they are asleep.

Turning off the lights can signal bedtime for puppies
Puppies require plenty of sleep to grow. Without it, they won't be able to develop properly. They need a safe, soft, and cozy bed where they can rest and gather much-needed strength.
Establishing a nightly routine can help train puppies to associate turning off the lights with bedtime. This routine could include a command that means it's the last time to go potty, followed by a biscuit and then bed.
Deep, restorative sleep in a dark environment for 7 to 8 continuous hours allows a puppy's body to produce normal melatonin levels. Lights at night can decrease melatonin levels and disrupt natural deep sleep. Studies have found that artificial light exposure right before bedtime negatively affects sleep and delays melatonin production.
However, it's important to note that puppies may refuse to enter a completely dark room. In such cases, leaving a night light on or using blackout curtains to create a dim light environment can help. Additionally, some high-energy breeds may benefit from putting a blanket or sheet over their crate to eliminate outside stimuli that may keep them awake.

Puppies sleep better in the dark as it reduces disturbances
Puppies, like most animals, tend to fall asleep when it gets dark. This is due to their circadian rhythms, which act as an "inner clock" that controls their sleep/wake cycle and is essential for many bodily functions. When it is dark, the dog's brain starts producing melatonin, a crucial hormone for healthy sleep. Deep restorative sleep in a dark environment for 7 to 8 continuous hours allows the body to produce normal melatonin levels.
Lights at night can decrease melatonin levels and disrupt natural deep sleep. Studies have shown that artificial light exposure right before bedtime decreased melatonin in humans by 99% and delayed it by about 90 minutes. Another study showed that light during a dog's sleep negatively affected its quality of sleep. Thus, a dark sleeping environment is one of the most essential factors in good sleep.
Puppies require plenty of sleep to grow, and without it, they won't be able to develop properly. Turning the lights off may help them get into the routine of "bedtime." It is a signal for them to sleep, and they will eventually become trained to associate the lights-off with bedtime.
However, it is important to note that puppies can sleep during the day, and sleeping during the day should be done in a light environment to maintain their circadian rhythm.

A night light may help puppies afraid of the dark
While puppies tend to fall asleep when it gets dark, they can't see in complete darkness and may refuse to enter a dark room. In such cases, it is recommended to leave a night light on.
Puppies require plenty of sleep to grow, and without it, they won't develop properly. They need a safe, soft, and cozy bed to catch up on their sleep. While puppies can sleep during the day, deep sleep cycles kick in when it's pitch black outside. As puppies grow into adults, their bodies develop adequate sleeping habits.
Leaving a light on for puppies may not be necessary, but it may be beneficial for older dogs. This is because, as dogs age, their vision deteriorates, and they may have difficulty seeing and navigating in the dark. A low light may help older dogs feel more comfortable and protected.
Additionally, some anxious or high-energy dogs may benefit from having a dark, quiet, and safe place. Consult your veterinarian to determine if this is suitable for your dog.
It is important to note that light exposure before bedtime can negatively impact sleep quality in both dogs and humans. Blue light, in particular, disrupts melatonin production, which is essential for healthy sleep. Therefore, it is recommended to minimize light exposure before bedtime and provide a dark sleeping environment for your puppy to ensure optimal sleep quality.
