6 Surprising Reasons Why Your Dog Cries in His Sleep

Understanding Dog Behaviour
By Liam Hartwell

Hearing your dog whimper or cry while sleeping can be unsettling for any pet owner. Is he dreaming? Is something wrong? Dogs, like humans, experience a range of emotions and physical conditions that can cause them to vocalize during sleep.

Understanding why this happens is essential to ensuring your furry friend stays happy and healthy. Below are six eye-opening reasons why your dog might cry in his sleep and what you can do about it.


1. He’s Just Having a Nightmare

Dogs dream just like humans, and sometimes those dreams can turn into nightmares. During REM sleep—the stage where vivid dreams occur—your dog may cry, whimper, or even twitch in response to whatever’s happening in his dream.

While it can be distressing to watch, nightmares are usually harmless. Avoid waking him suddenly, as this can startle him.


2. He Hasn’t Been Trained to Stop

Crying or vocalizing during sleep may be an ingrained behavior if your dog hasn’t been trained otherwise. Puppies, in particular, may cry during naps because they are still learning to self-soothe. Over time, with patience and consistent routines, this behavior often fades.


3. It’s Separation Anxiety

Dogs suffering from separation anxiety may carry their stress into their sleep. If your dog spends the day worrying about being away from you, it can cause restless and emotional sleep patterns, resulting in crying or whimpering.

Signs include pacing before bedtime, clingy behavior, and excessive vocalization when you’re not around.


4. He’s Afraid of Something

Loud noises like thunderstorms, fireworks, or unfamiliar sounds can make dogs anxious, and that fear can continue into their sleep. Dogs who are sensitive to certain triggers may cry or whine during dreams when those fears manifest.

Creating a safe, cozy sleep environment can help your dog feel more secure.


5. He’s Having a Seizure

While it’s far less common, crying or vocalizing in sleep can sometimes indicate a seizure. Seizures during sleep often cause uncontrollable movements, stiff limbs, excessive drooling, or crying sounds.

If you suspect seizures, consult a veterinarian immediately to determine the cause and explore treatment options.


6. It’s Some Other Health Issue

Pain, discomfort, or an underlying health issue might also cause your dog to cry during sleep. Conditions like arthritis, injury, or digestive issues can make lying still uncomfortable, even when your dog is sleeping. If your dog’s whimpering is frequent or accompanied by lethargy or other symptoms, a vet visit is necessary.


How Can I Prevent My Dog from Crying in the Future?

Here are some tips to help your dog sleep peacefully:

  • Create a Comfortable Sleeping Space: Ensure your dog has a soft bed in a quiet, secure area.
  • Exercise Regularly: Tiring your dog out during the day helps promote deeper, more restful sleep.
  • Reduce Stress: If separation anxiety is an issue, try desensitization techniques or calming aids.
  • Regular Vet Visits: Rule out any medical issues that may be causing discomfort or pain.

Does Waking Him Up Work?

Waking your dog up may stop the crying temporarily, but it isn’t always the best approach. Startling your dog during a deep sleep can leave him disoriented or scared. Instead, gently call his name or softly pet him to bring him out of the dream without shocking him awake.


In Conclusion

Your dog’s nighttime whimpers might be as simple as a bad dream or a sign of something more significant, like anxiety or a health issue. By observing his behavior, creating a calm sleeping environment, and consulting your vet when needed, you can help ensure your pup sleeps peacefully through the night.

A little understanding and care go a long way in making sure your furry companion rests easy—dreams and all.
