Yes, some dogs can sleep with their eyes open, or at least partially open. This behavior might look unsettling, but it’s not necessarily a sign of a problem. Many dogs do this occasionally, and for most, it’s completely normal.

3. Why Do Dogs Sleep With Their Eyes Open?

There are a few reasons dogs might sleep with their eyes open or partially open:

  • Protective Instincts: In the wild, sleeping with eyes slightly open may help dogs stay alert to danger.

5. Should You Be Concerned?

While sleeping with open eyes is generally harmless, you should watch for signs of potential problems, including:

  • Dry, red, or irritated eyes
  • Excessive tearing or discharge
  • Cloudy or dull-looking eyes
  • Sudden behavioral changes or lethargy

If you notice these symptoms, consult your veterinarian to rule out any underlying issues.

6. Medical Conditions That May Cause Dogs to Sleep With Their Eyes Open

Although rare, some medical conditions can cause or contribute to this behavior:

  • Lagophthalmos: A condition where dogs can’t fully close their eyelids
  • Seizures or Neurological Disorders: Can affect muscle control during sleep
  • Injuries: Trauma or scarring around the eyes can limit eyelid movement

Always monitor your pet for unusual behaviors and consult your vet if anything seems off.

7. How to Tell If Your Dog Is Really Asleep

Even if your dog’s eyes appear open, look for these signs of actual sleep:

  • Regular breathing and body stillness
  • Ear twitching or paw movement (dreaming)
  • Unresponsiveness to quiet noises
  • Snoring or soft vocalizations

If these signs are present, chances are your dog is simply sleeping—with eyes partly open.

8. What You Can Do If You’re Worried

If your dog frequently sleeps with their eyes open and you’re concerned, here are a few steps you can take:

  • Use a humidifier: Helps prevent dry eyes, especially in winter
  • Limit exposure to bright lights while sleeping
  • Keep a sleep log: Track patterns and any changes in behavior
  • Visit your vet: Especially if you see signs of eye discomfort
