Why is my dog snoring all of a sudden?

Your dog is snoring all of a sudden due to their change in sleeping position. It can also be from allergies, rhinitis, foreign objects on their nose, or obesity. Sometimes, it can be from medical issues. Examples are nasal tumors, infections, laryngeal paralysis, or tracheal collapse.

7 reasons why your dog is snoring all of a sudden?

#1: It’s due to their position

For some reason, your dog enjoys sleeping on your bed with you…

And this time, you’re saying yes to their request.

Now, it’s been going peacefully as Fido’s fast asleep beside you.

Not until they begin to snore loudly…

What’s up with that?

It might be due to your dog’s change in sleeping position.

Say that one moment they’re lying on their side. During that, your fur baby doesn’t make any noise.

But when your pooch rolled a little, it made them snore suddenly.

That’s because they’re sleeping on their back.

And when they’re lying like that, their tongue is partially blocking their throat.

With that, their airways are somewhat blocked. And that causes them to breathe noisily and snore while they’re asleep.

#2: Allergies

Your Dog Is Snoring All Of A Sudden Because He Has Allergies

Imagine this:

You’ve been busy all day as you’re cleaning around the house.

It’s a habit where you clean every room and every corner.

So, you move a few pieces of furniture here and there. Then, you also dust everything around.

Now, it’s time for you to get your night’s rest.

But that seems to be impossible…


Because your fur baby is snoring so loudly.

Aside from your sleep, you’re also concerned with your dog.

They’ve never snored before.

So what could it be?

Let me tell you that it might have something to do with today’s activities.

Hear me out…

When you cleaned around, more dust came flying around in your place.

With that, your pupper’s having an allergic reaction to the dust.

Moreover, that’s not the only situation that dogs can get inhalant allergies.

VCA Hospitals say pollens, grass, or molds can bring the same condition.

Plus, here are other signs of allergies in dogs:

Moreover, there’s another kind of allergy that might cause your pooch to snore suddenly.

Vets call it seasonal allergies

That type shows during specific times of the year.

For example, it can be in the summer. That type of season is when most flowers bloom, and the grass is greener…

With that, your pooch develops a sudden allergy. Thus resulting in unexpected snoring.

#3: Rhinitis

Sometimes, the cause looks like it’s allergies…

But it’s not…

Instead, it can be rhinitis.

What’s that?

Let me break it down.

The “rhin” refers to the nose. Then, “-itis” means it has something to do with inflammation.

Put that together, and you have inflammation of the nose.

Note: This condition is often mixed up with sinusitis. However, sinusitis refers to the inflammation of the sinus.

That aside, the MSDVM says that the causes of rhinitis vary.

But for the sudden show of this condition, a viral infection might be behind it. Those are:

  • Canine distemper.
  • Canine parainfluenza.
  • Canine adenovirus (type 1 and 2).

Moreover, the signs of rhinitis are:

  • Sneezing.
  • Pawing the face.
  • Nasal discharge.
  • Shortage of breath.
  • Open-mouth breathing.

And, of course, snoring is a tell-tale sign of rhinitis.

As for the treatment…

Mild cases won’t need much. You’d only have to focus on relieving the signs of this condition.

But if it’s severe, vets will prescribe medications depending on the specific cause.

#4: Foreign objects


Foreign Objects

Something might be stuck on your dog’s nasal passages.

And that’s why they’re snoring all of a sudden.

So, go and see it for yourself…

Point a flashlight on your dog’s nose and see what’s lodged in there.

Some examples of what you may find are:

  • Grass.
  • Cotton balls.
  • Wood sticks or twigs.
  • Stuffing from their toy.
  • Pieces of chewed plastic or fabric.

If those are present on your dog’s nose, then that’s it…

That’s the reason behind their sudden snoring.

Moreover, the MSD Vet Manual says that this can also cause rhinitis. And as I mentioned, that can also suddenly lead to your dog snoring.

Lastly, these are the signs that something’s stuck on your dog’s nose:

  • Taking noisy breaths.
  • Changes in breathing.
  • Discharging mucus to one nostril only.

Removal of the object

If it’s simple to see, then it might be easy to grab…

So, settle your dog down and make sure they’re calm.

Use a pair of tweezers in trying to remove the object.

Warning: Make sure that you don’t push the object any further. Doing so can make things worse.

So if you want what’s really best for Fido, I suggest having a vet do the removal.

According to this study, retrieval of the foreign body is done through rhinoscopy.

They also have data that shows the following:

Location of the foreign objectData among 42 dogs
Right nasal cavity52.4%
Left nasal cavity42.9%
Each nasal cavity4.8%

#5: Nasal tumors

Something’s still blocking your dog’s nasal passages…

That’s why they’re suddenly snoring…

But this time, you can’t just remove it using a tweezer.

That’s because it can be a nasal tumor.

“That sounds serious…”

This research says that it is.


It’s because the most common nasal tumor is nasal adenocarcinoma. And that’s just another term for nose cancer.

Moreover, the study shows that out of 112 dogs, 85 suffer from the condition.

Now, what happens when your canine has nasal tumors or nose cancer?

VCA Hospitals say that cell production is uncontrolled in the nasal lining. And that drives the growth of tumors.

Then, that growth creates an obstruction in your pup’s airways.

All in all, it leads to sudden snoring. 

And not only that, but this condition also leads to:

  • Lethargy.
  • Coughing.
  • Weight loss.
  • Noisy breathing.
  • Nasal discharge (with pus or blood).

To diagnose this, your pooch has to undergo many scans.

And as for its treatment, the best choice would be radiation therapy.

#6: Respiratory problems

Trying to trace the explanation behind your dog’s snoring problem, right?

Well, don’t just look at their nose…

That’s because the whole respiratory system might be involved with it.

So, here are the specifics…

Laryngeal paralysis

Have you noticed that bump on your dog’s throat? 

You might know it as their Adam’s apple

However, the real term to call it is their larynx or voice box.

And there might be a problem with it that causes your dog to snore all of a sudden.

The condition is called laryngeal paralysis.

According to the MSDVM, it happens when the larynx malfunctions. The cartilage in it doesn’t open and close normally anymore.

With that, your pooch struggles to breathe properly.

Moreover, it causes them to respirate loudly. Hence the sudden snoring and other signs like:

  • Vomiting.
  • Dry cough.
  • Regurgitation.
  • Voice changes.
  • Getting exhausted easily.

Tracheal collapse

Another body part to suspect is your dog’s trachea.

What’s that?

It’s the tube that brings air from the nose and mouth to the lungs.

Now, the damage of that body part can lead to tracheal collapse. 

According to PetMD, this is a common disease in dogs.

Moreover, the symptoms of it are:

  • Fainting.
  • Retching.
  • Chronic cough.
  • Rapid breathing.
  • Blue-tinged gums.
  • Exercise intolerance.
  • Struggling to breathe.

Then, it also causes the so-called goose-honk. It’s a type of cough that sounds like the name suggests.

Most of all, it can be the culprit for your dog’s unexpected snoring.

Bacterial pneumonia

The first 2 conditions I mentioned are part of the upper respiratory tract…

Now, this one that I’m gonna talk about belongs to the lower respiratory tract.

To be specific, the airways and lungs are affected.

By what?

None other than bacterial pneumonia…

What’s that?

VCA Hospital describes it as the inflammation in the lungs. And it’s a result of an injury, infection, or irritation in the said body part.

But they stated that bacterial infection causes most cases of pneumonia in dogs.

According to research, such is also called bacterial invasion. Plus, it mainly affects young dogs.

Now, what are the signs of this condition? They are:

  • Lethargy.
  • Anorexia.
  • Coughing.
  • High fever.
  • Weight loss.
  • Dehydration.
  • Difficulty breathing.
  • Getting tired easily (decreased tolerance).

Most of all, snoring all of a sudden can be a symptom of bacterial pneumonia.

So, let’s try to put it all together…

Your pooch used to be a healthy pupper. 

However, they start to snore all of a sudden…

And along with that are those signs. Like Fido doesn’t wanna play too much anymore.

They’d rather rest or do nothing…

With that, you must bring them to the vet immediately. Many of the medical conditions I mentioned might be the ones to blame.

#7: Obesity

Is this how your pooch looked like when you caught them snoring all of a sudden?

Are they as chubby as the dog in the video? Or they’re more chunky?

If you answered yes to one of those questions, then that might be the cause.

Yep, obesity can cause your dog to snore all of a sudden.


Overweight dogs have many excess fats in their body.

And when they sleep, those fats put pressure on their breathing.

Moreover, they struggle to breathe as fats might be pushing on their ribcage. With that, their respiratory system has a hard time in respiration.

Lastly, fats can also be present in their tissues. Such causes the narrowing of airways on the nasal cavity and palate.

Should I worry if my dog is snoring all of a sudden?

You should worry if your dog is snoring all of a sudden. It’s normal for some dogs to snore, especially brachycephalic dog breeds. But sudden snoring can be a sign of an underlying medical condition. Examples are respiratory issues, nasal tumors, rhinitis, or allergies.
