As a devoted dog owner, you’ve likely noticed your furry friend’s eyes rolling back into their head while they’re snoozing. This seemingly unusual behavior can sometimes raise concerns, making you wonder if your dog is okay. Understanding why dogs’ eyes roll back when sleeping is crucial for ensuring their well-being and alleviating any anxieties you might have.
Why Do Dogs’ Eyes Roll Back When Sleeping?
The rolling back of a dog’s eyes during sleep is a natural and common phenomenon. It’s not a cause for alarm and usually indicates that your dog is simply enjoying a deep, restful sleep.
Muscle Relaxation and Eye Position
During sleep, our muscles relax, and this includes the muscles that control our eyelids and eye movement. In dogs, the muscles that hold the eyelids open are particularly relaxed during deep sleep, allowing the eyes to naturally roll back slightly. This is a normal physiological response and doesn’t signify any underlying health issues.
Dreaming and Brain Activity
Just like humans, dogs dream. While they sleep, their brains are still active, processing information and creating vivid dream sequences. The rolling back of the eyes during sleep may be related to these dreams, as the brain sends signals to the muscles, causing them to twitch or move involuntarily.

Understanding Canine Sleep Cycles
Dogs, like humans, experience different stages of sleep. One of these stages is called rapid eye movement (REM) sleep. This is the stage where most dreaming occurs, and it’s characterized by rapid eye movements, twitching muscles, and increased brain activity.
REM Sleep and Eye Rolling
During REM sleep, a dog’s eyelids may partially close, but their eyes can still move rapidly beneath the lids. This movement can sometimes cause the eyes to appear to roll back into the head.
Other Possible Reasons
While REM sleep is the most common explanation for rolling eyes in sleeping dogs, there are a few other possibilities to consider:
- Muscle Relaxation: As dogs drift off to sleep, their muscles relax. This relaxation can extend to the muscles around the eyes, causing them to appear rolled back.
- Breed Predisposition: Some breeds, such as brachycephalic breeds (dogs with short noses), may be more prone to having their eyes roll back during sleep due to the shape of their skulls.
- Underlying Medical Conditions: In rare cases, eye rolling during sleep could be a sign of an underlying medical condition, such as neurological disorders. If you notice any other unusual symptoms alongside eye rolling, it’s important to consult with your veterinarian.
When to Worry
In most cases, rolling eyes during sleep are nothing to be concerned about. However, it’s important to pay attention to your dog’s overall behavior. If you notice any of the following, it’s best to consult with your veterinarian:
- Excessive Drooling
- Difficulty Waking Up
- Seizures or Tremors
- Changes in Appetite or Water Intake
Recap
Rolling eyes during sleep is a common and generally harmless behavior in dogs. It is most often associated with REM sleep, where rapid eye movements occur. While some breeds may be more prone to this, it’s important to consult with your veterinarian if you notice any other unusual symptoms alongside eye rolling.

Why Do My Dogs Eyes Roll Back When Sleeping?
Is it normal for dogs’ eyes to roll back when they sleep?
Yes, it’s perfectly normal for dogs’ eyes to roll back when they’re sleeping, especially during deep sleep stages. This is called “tonic immobility” and it’s a natural reflex that occurs in many animals, including humans.
What does it mean if my dog’s eyes roll back while sleeping?
When your dog’s eyes roll back, it usually means they’re in a deep, restful sleep. Their muscles are relaxed, and their eyelids may even partially close. This is a sign that your dog is comfortable and safe.
Is there anything I should worry about if my dog’s eyes roll back?
Generally, there’s no need to worry if your dog’s eyes roll back occasionally during sleep. However, if you notice any other unusual symptoms, such as excessive drooling, snoring, or difficulty waking, it’s best to consult with your veterinarian.
Why do some dogs roll their eyes back more than others?
The amount of eye rolling during sleep can vary from dog to dog. It depends on factors like breed, age, and individual sleep patterns. Some dogs are simply more prone to this reflex than others. (See Also: Where To Buy Valu Pak Dog Food)
How can I tell if my dog is dreaming when their eyes roll back?
It’s impossible to know for sure if your dog is dreaming just by observing their eyes. However, if you notice other signs like twitching paws, whimpering, or changes in breathing, they may be experiencing a dream.
