Is It Normal For Dogs To Sleep With Their Eyes Open?
Do you often find your dog sleeping with their eyes open? Does the sight freak you out? While it is not that uncommon for dogs to sleep with their eyes partially open and it is not always worrisome or indicative of any medical problem in your beloved furry friend, this can occasionally be a symptom of an illness. So, why do dogs sleep with open eyes?
Here are some interesting facts about this condition in your canine:-
Reasons Why Dogs Sleep With Their Eyes Open
Survival Instinct
Dogs in the wild were built to stay alert all the time for any surrounding environmental threat. Domestic dog breeds carry this instinct due to which they can have their eyes partially open while sleeping.
Sleep Cycle
Dogs have shorter sleep cycles as compared to their human companions. There are chances that when you look at them thinking they are asleep with eyes open, they are partially awake and are just relaxing between the naps.The Third Eyelid
Dogs have an inner third eyelid called a nictitating membrane that keeps their eyes protected from dirt, dust and bacteria. This third eyelid protects your dog’s eyes and becomes more visible while they are resting. So, when you think that your dog is sleeping with their eyes open, it is actually this third eyelid that you are looking at.REM Sleep Disorder
If you see your dog twitching or growling while sleeping, or if you see abnormal eye movements, it could be because your dog is dreaming. This behavior can be the result of REM (Rapid Eye Movement) disorder, where the eyes of your dog are partially open during sleep.Medical Condition
Your dog may also be suffering from a medical condition due to which you observe them sleeping with their eyes open. In case of a medical condition, consulting a veterinarian to provide proper treatment to your dog is necessary.Cherry Eye
Common in dogs with squished faces like bulldogs or Boston terriers, cherry eye is a condition where the third eyelid of the dog gets swollen red, like a cherry. Because of the swelling, your dog is unable to close the eyes completely. This leads to having their eyes partially open while sleeping.Lagophthalmos
Pugs and shih tzus are more prone to this condition. In such a condition, your dog is unable to close their eyes completely because the globe of the eye is too big to get covered by the eyelids. Diseases like glaucoma or genetic disorders could be the reason behind it.When To Consult The Professional
Sleeping with eyes open is not always normal for dogs. There are chances that your dog may be suffering from an illness and will require medical intervention or a visit to a veterinarian.Narcolepsy
Mostly a hereditary condition seen commonly among poodles, dachshunds, and Labrador retrievers, narcolepsy is a condition in which your dog falls asleep suddenly between waking and sleeping states even while in active conditions like playing or running. This may look like seizures, but it is just the state of dreaming. Though not completely curable, medicines can help in reducing the frequency of narcolepsy attacks.Epilepsy (seizures)
When your dog experiences seizures, they will suddenly lie down with eyes wide open and show a blank expression, will be unresponsive to your voice and may look like they are sleeping with eyes open. Common in breeds like Labrador retrievers and golden retrievers, seizures need treatment and a visit to a veterinarian post-seizure attack is a must for keeping your dog safe.
