Why Does My Dog Whimper in His Sleep

You may have seen your dog move, twitch, or shake in their sleep, but have you ever heard your pup whimper in their sleep? As a pet parent, you will naturally do anything to help when it sounds like they are in distress. So, is there something you can help when your dog whimpers in their sleep? You could try to address the cause. Some examples include stress, pain, and discomfort.

Providing a comforting sleeping environment with a good dog bed can help. It goes a long way in ensuring your pup is physically comfortable. That, in turn, can help ease their anxiety and provide them with a peaceful night’s rest. However, comfort may only be part of the problem.

To answer your questions about why your pup whimpers in their sleep, we are going to take a deep dive into Canine Behavior Insights by Dr. Bonnie V.G. Beaver, DVM. So, let’s take a closer look at why your pup whimpers in their sleep.

So let’s take a closer look at why dogs whimper in their sleep.

The Top 6 Reasons a Dog May Whimper in Their Sleep

Is It Normal for a Dog to Whimper in Their Sleep? Understanding why your dog is whimpering in their sleep can help you act appropriately. The main reason that dogs twitch, yelp, bark, whimper, kick their feet in their sleep is today with something called REM. 

So when we discuss dogs whimpering or crying in their sleep, we will focus mostly on the concept of dreams and the sleep cycle. 

1. Dreaming and REM Sleep When Dogs Whimper

Dogs, like humans, probably have vivid dreams while they sleep. Although we can’t prove that they dream, their brain waves during REM sleep suggest that they dream just like we do. Dogs, just like us, have different sleep stages, and one of them is called REM sleep, which stands for Rapid Eye Movement.

During REM sleep, dogs experience intense brain activity, and their eyes move rapidly under their adorable eyelids. And yes, it is possible that your dog is whimpering because they are having a nightmare.

Now, here’s the scoop on sleep cycles. Dogs go through different stages of sleep, including light sleep, deep sleep, and REM sleep. They cycle through these stages multiple times during their slumber. It’s important to note that REM sleep is when dogs are most likely to show movement, like wagging their tails, twitching their paws, or even whimpering.

So, are those sweet whimpers a sign that our furry buddies are dreaming? Well, it’s highly possible! Dogs tend to dream during REM sleep, just like we do. So, when you see your pup whimpering or making those adorable noises, it’s like they’re acting out their dreams. 

Should I Wake My Dog When They are Whimpering in Their Sleep?

If your dog is dreaming and whimpering, it’s usually better not to wake them unless they sound extremely distressed. This is because dreaming is a normal and healthy cognitive process and part of the sleep cycle we will discuss more below.

Dreaming in dogs has a purpose that scientists are still studying and trying to understand. We believe that dreaming helps dogs consolidate memories, learn new things, and process emotions. When dogs dream, they may replay experiences they’ve had, which can help them strengthen their memory and problem-solving skills.

Dreaming may also help dogs regulate their emotions, allowing them to work through and cope with stressful or challenging situations. While we may not know exactly what dogs dream about, it is clear that dreaming plays an important role in their mental well-being and cognitive development. So if your dog is whimpering while sleeping, it’s best to let them sleep and their brain complete its natural function.

Remember, it’s all part of their normal sleep behavior, and there’s no need to worry. If your dog seems comfortable and isn’t showing any signs of distress while sleeping, then sit back, relax, and enjoy the adorable show.

Is Whimpering While Sleeping in Dogs Normal? What We Need to Know About the Dog Sleep Cycle

Dogs have a sleep pattern that consists of different sleep-wake episodes. On average, they have around 23 of these episodes per hour during an 8-hour period of sleep. Each episode involves a period of sleep lasting 5 to 16 minutes, followed by a 5-minute period of wakefulness.

One interesting stage of sleep for dogs is active sleep, which is believed to be their equivalent of REM sleep. During this stage, dogs may exhibit behaviors like paddling with all four limbs and vocalizing, as air is pushed through their larynx. It’s just like our own REM sleep, where dreaming occurs in humans. 

While it’s impossible to prove definitively whether dogs dream, the presence of REM sleep suggests that they might experience dream-like activities. In a span of 24 hours, the average dog spends approximately 9.7 hours in quiet sleep, which includes both light and deep slow-wave sleep. 

They typically spend between 2.3 and 3.3 hours in active REM sleep. It’s important to note that dogs in REM sleep can be easily awakened by external stimuli, which might explain why they seem alert and responsive even during their dream-filled slumber. This is one reason dogs like to bark at night and you may wonder if they ever get tired of barking.

2. Physical Discomfort

Another possible cause dogs may whimper while resting is physical discomfort. Just like humans, dogs can experience muscle twitches, cramps, or other forms of pain that lead to whimpering during sleep. Dogs with chronic pain may grunt from a problem like arthritis may grunt or cry at times. 

Other problems like acid reflux in dogs can be a problem when they sleep, as lying down can push stomach acid up along their esophagus, causing discomfort. Similarly, dogs with congestive heart failure, CHF, can have trouble sleeping because the fluid build-up disrupts their ability to breathe.

If you hear your dog whimpering while lying down, make sure they are really asleep, and the whimpering is not happen from pain or other issues while the dog is actually awake.

Be aware of sudden behavioral changes like a dog seeming to grow distant if you suspect your dog’s whimpering when lay down has a medical cause. 

3. Emotional Responses like Anxiety and Stress

It is possible that the emotions or stress dogs feel when awake can continue into their dreams, or even cause nightmares just as it does for humans. One reason for whimpering in sleep may be anxiety, including separation anxiety

4. Sleep Talking

Whimpering can be a form of sleep-talking for dogs. These vocalizations can range from soft whimpers to more audible sounds. 

5. Advanced Age

Old age can lead to changes in a dog’s body and brain, possibly contributing to whimpering during sleep. As dogs age, they may experience arthritis, joint pain, or general discomfort. In addition, cognitive dysfunction disorder, or CDD, affects their perception. 

6. Healthy Conditions

Scientists don’t know for sure yet, but it would seem that preexisting conditions that cause seizures can contribute to whimpering in dogs during sleep. That may be down due to the impact on their neurological system. 

Health conditions like brachycephalic airway syndrome in short-nosed breeds, heart, or respiratory conditions can all affect a dog’s ability to sleep and sometimes leads noises when they rest.

When to Be Concerned About Dog Whimpering in Sleep

Whimpering in their sleep is generally harmless to dogs. However, there are situations where it’s essential to respond and contact a vet. If visible signs of distress accompany the whimpering, it may indicate a more serious problem. Concerning symptoms include intense shaking, excessive drooling, or abnormal breathing patterns. 

How to Help Your Dog Stop Whimpering in Their Sleep

Create a Cozy Sleeping Space

Ensure your dog has a comfortable bed or crate with soft bedding. A familiar and cozy environment can promote better sleep and reduce the likelihood of whimpering.

Establish a Bedtime Routine

Dogs thrive on routine, so establishing a consistent bedtime routine can help them feel more secure and relaxed.

Address Underlying Anxiety

If your dog has anxiety issues, consult a professional dog trainer or behaviorist to develop a plan for managing their anxiety. 

Increase Exercise and Activity

Tired dogs are deep sleepers. The more activity your dog gets in their day, the deeper they should sleep, and the less restlessness they should have at night. See our articles on how to workout with your dog.

Check for Underlying Health Problems

Dogs who have problems sleeping at night because they have sleep apnea, chronic pain, heart conditions, or neurological issues, may need veterinary treatment.

Identifying the Cause of Dog Whimpering in Sleep

To effectively address the matter, it’s essential to identify the underlying cause. Pay attention to any patterns or triggers that may distress your dog. Keep a journal to note the frequency and duration of whimpering episodes. You can then see if the whimpers match up with changes in their environment or routine.

Solutions & Preventing Your Dog from Whimpering in Their Sleep

  • Stick to a consistent sleep schedule: Maintain a consistent sleep schedule for your pup. It can help regulate their sleep cycle and reduce potential disruptions during the night.
  • Provide regular exercise: Ensure your dog gets enough exercise during the day. That can help them burn off excess energy and promote better sleep at night. Physical activity can also contribute to reduced anxiety.
