Do I Need To Be Concerned About My Cavalier King Charles Snoring?

If you’re a proud owner of a Cavalier King Charles Spaniel, their comfort and well-being are likely a top priority for you. 

So, when you hear your furry friend snoring, it’s natural to be concerned.

Snoring can sometimes be just a harmless, temporary issue, but it can also be a sign of an underlying health problem. 

How Do I Know if My Cavalier King Charles Snoring is a Serious Issue?

Is it normal for a Cavalier King Charles to snore?

It’s essential to be mindful of your Cavalier King Charles Spaniel’s snoring and understand when it might indicate a more serious issue. 

Here are some signs that you should be concerned:

  • Loud or persistent snoring 
  • Other symptoms – If your pet has other symptoms like coughing, difficulty breathing, or a change in appetite, this could be a red flag.
  • Interrupted breathing 
  • Snoring worsens over time 

To ensure your pet is healthy and comfortable, it’s always best to consult a vet. 

They can assess your Cavy’s snoring, help determine the root cause, and provide personalized advice and treatment options if necessary.

Why Does My Cavalier King Charles Spaniel Snore?

Let’s take a look at some of the possible causes of your cavalier’s snoring habits.

Brachycephalic Airway Obstruction Syndrome (Baos)

Brachycephalic airway obstruction syndrome (BAOS) is the leading cause of snoring and respiratory difficulties in Cavalier King Charles Spaniels and other flat-faced breeds such as pugs and bulldogs.

These dogs are prone to breathing problems due to their unique anatomy, with features such as a long soft palate that extends past the epiglottis, making it difficult for air to pass through. 

Narrow nares that can collapse during inhalation also contribute to difficulty breathing through the nose resulting in snoring.

Fungal Infections

Fungal infections or Aspergillosis is a sneaky enemy, creeping into your pup’s body through the nasal passages after they’ve taken in moldy air during a walk outside. 

This infection can cause snoring in dogs by causing nasal swelling and discharge in the nasal cavity.

But don’t worry; with the right meds, you can banish this infection and the snoring (hopefully) in no time!


Like humans, our furry friends can also be sensitive to their environment. 

Suppose you’ve noticed your pup’s snoring increases during specific times of the year, like spring or autumn. In that case, allergies could be the culprit.

Allergens in the air, such as dust, mold, mites, smoke, and pollen, can lead to a range of symptoms in dogs that can contribute to snoring, including: 

  • Sneezing 
  • Congestion
  • Runny noses
  • Difficulty breathing

Additionally, with their long, thick fur, your pet dog can be particularly susceptible to allergies.

These allergens can easily get trapped in their fur and irritate their airways, leading to persistent snoring issues or it might leave your Cavalier possibly not sleeping at night too.


Although it sounds daunting, these growths can cause blockages and obstruct normal breathing, leading to snoring. 

It’s important to take your dog to a vet for a proper evaluation to determine the location and extent of the tumors, as prompt treatment is essential for their well-being and comfort. 

And if your snuggly companion doesn’t have tumors, then you know they are healthy!

Sleep Apnea

Sleep apnea is a condition that can cause snoring in King Charles Cavaliers because the pauses in breathing can narrow or close their airway, leading to loud snoring. 

Additionally, frequent waking and loss of deep sleep can leave the dog tired and lethargic during the day, leading to more severe health problems if left untreated.

Sleeping Position

Have you ever caught your furry friend snoring away on their back? Well, this position can undoubtedly lead to some sounds during sleep time.

While tummy sleeping is the norm for these lively pups, they may sometimes roll onto their backs, causing gravity to work its magic and loosen the mucous membrane in the throat, putting pressure on the airway. 

And with obstacles in the way, the air can’t flow freely, leading to those telltale snoring vibrations. 

So, the next time you hear your pup snoring, think about their comfy sleeping position!


Winter is not a favored season for Cavalier King Charles Spaniels, who struggle to withstand the low temperatures and are prone to respiratory infections during the colder days. 

Their short muzzles and respiratory tracts make them particularly vulnerable to illness. 

Puppies, senior dogs, and those with underlying health conditions that weaken their immune system are at a higher risk of catching a cold. 

If your Cavy is under the weather, you may notice a runny nose and sneezing, leading to irritation, swelling, and difficulty breathing. 

During the day, your pup may breathe loudly and snort, whereas snoring is likely due to their cold at night.

Poor Teeth Alignment

Poor teeth alignment or Cavaliers with an underbite can cause snoring as it can obstruct the airway, making airflow difficult. 

If the airway is blocked or partially obstructed, it can lead to snoring during sleep. 

Additionally, when teeth are not aligned properly, it can cause a change in the shape of the jaw and soft palate, further restricting the airway and leading to snoring.


Cavalier King Charles Spaniels are known for their energetic nature but tend to become overweight, particularly as they age. 

Excess weight can put them at risk for various health problems, including snoring. 

Fat deposits that accumulate around their neck are particularly problematic and can directly impact their breathing.

The buildup of fat under their skin and around their organs can squeeze their airways, leading to snoring. 

This narrowing creates an annoying sound and can lead to severe breathing problems and sleep apnea.


As Cavalier King Charles Spaniels grow older, snoring is often a concern among owners. This may be due to weight gain, decreased activity, or an altered sleeping position. 

With age, the tissues in their throat become more relaxed, causing vibrations during breathing and resulting in snoring.

How Do I Stop My Cavalier King Charles From Snoring 

Nobody enjoys listening to the melodies of a snoring pooch at 3 am, so here are some possible solutions to stop your dog from snoring.

Give It A Comfortable Bed

Making sure your pup has a designated sleeping spot is vital to a peaceful sleep for you and your pooch. 

And if you’re looking to combat snoring, you must invest in a quality bed.

I’ve found that a memory foam orthopedic bed with raised edges is a game-changer for my pooch.

It offers them a comfortable place to rest their heads and helps clear their airways. 

Plus, adding a pillow for extra coziness is always a good idea. Just remember to keep the bed clean and clutter-free by using a washable cover. 

And steer clear of letting your pup stash their toys in their bed, as that’s where dust, mites, and allergens can accumulate.

Key Benefits

  • Pressure-relieving memory foam and durable support foam to create a bed that loves Fido back.
  • Excess material on top for dogs that like to dig and scratch to make the perfect sleeping spot
  • Supportive foam bolsters on the mattress create a safe space for dogs to lay their heads
  • Microfiber blended material designed to be durable and rip-resistant
  • Removable and machine washable cover that’s impenetrable to fur slobber-resistant.

Buy A Humidifier 

If your Cavalier is a snorer, dry air might be the culprit. 

A dry throat is just as uncomfortable for dogs as it is for us. If the air in your home is lacking in humidity, it could contribute to your furry friend’s snoring.

Here is a list of the best humidifiers for dogs I compiled. You should check it out too!

Another thing to remember is that indoor smoking can irritate a dog’s sensitive airways and make snoring worse.

Investing in an air purifier and humidifier can help end your Cavalier King Charles’ snoring issues. 

Not only does it increase the moisture in the air, but it also removes allergens and tobacco smoke, which may be contributing to your Cavvy’s symphony of snores.

Give It Plenty Of Exercise

Exercise helps reduce snoring in Cavalier King Charles Spaniels by promoting weight loss, strengthening respiratory muscles, and reducing airway obstruction. 

It also helps regulate breathing patterns and ensures that your pet remains in good physical shape, reducing the likelihood of snoring. 

Regular exercise can also be a great way to keep your Cavy active and healthy, further enhancing their overall well-being.

Reduce Allergens And Irritants

Reducing allergens and irritants in your dog’s environment can help decrease the likelihood of snoring. 

Allergens such as dust mites, tobacco smoke, and certain household chemicals can cause inflammation in your dog’s airways, making it difficult for them to breathe and leading to snoring. 

Removing these irritants and maintaining a clean environment can help keep your dog’s airways clear and reduce the likelihood of snoring. 

This can be accomplished through regularly cleaning your home, using air purifiers, and avoiding smoking indoors.

Ensure A Healthy Diet

Suppose you find yourself falling for those irresistible, pleading puppy eyes whenever your Cavalier begs for food.

In that case, it’s time to realize that you might not be doing them a favor. 

Overfeeding and indulging in too many treats and snacks can lead to weight gain and, as a result, snoring. 

And it’s not just the snoring that’s a problem; it can also cause a host of more serious health issues.

It’s up to you to help your Cavy shed pounds by ensuring they follow a balanced diet rich in fiber and protein, with high-quality food that keeps them healthy and slim.

Adjust Their Sleeping Position

Take a closer look at your pup’s nap time habits. 

If they’re sleeping on their back with their head or neck lower than their body, this posture can interfere with normal breathing and result in snoring. 

The solution is easy – switch up their sleep position! Have your Cavy snooze on their side to reduce pressure on their throat. 

If they keep flipping onto their back, place a pillow or rolled blanket behind them to prevent it.

Seek Treatment 

A trip to the vet can shed light on many questions, especially if your Cavalier King Charles Spaniel’s snoring seems unusual or accompanied by other symptoms. 

Your vet will ask you questions and examine your pet to determine the root cause of the snoring.

To aid in the diagnosis, it can also be helpful to record your dog while they sleep. This will give your vet valuable information to make a more accurate diagnosis. 

If an illness or condition causes your Cavy’s snoring, you must follow your vet’s recommendations for at-home care and medication regimen.
