Reverse Sneezing in Dogs: Causes and What to Do

One moment your dog is fine, and the next, they’re making strange snorting or honking noises, stretching their neck, and seeming like they’re gasping for air. If you've witnessed this and felt alarmed, you're not alone. It’s called reverse sneezing, and while it sounds dramatic, it’s usually harmless.

Reverse sneezing, medically known as paroxysmal respiration, is a common reflex in dogs that occurs when something irritates the back of their throat or nasal passages. Unlike a regular sneeze that pushes air out, reverse sneezing pulls air in, causing that distinctive snorting or wheezing sound.

While it might look or sound scary, especially if you’re a first-time pet parent, reverse sneezing episodes typically resolve on their own in under a minute and don’t cause any long-term harm.

In this article, we’ll cover:

• What reverse sneezing looks and sounds like
• What causes it
• How to help your dog during an episode
• When it’s time to see your vet
• How your dog’s diet might play a role in reducing triggers

What Does Reverse Sneezing in Dogs Look and Sound Like?

If you’ve never seen it before, a reverse sneeze can feel like a red-alert emergency. Your dog might:

• Suddenly stop in their tracks
• Extend their neck and stiffen their posture
• Begin snorting rapidly, almost like a goose honking
• Gasp or wheeze inward in a series of rapid inhalations
• Appear panicked—but often recover quickly

Many pet parents describe it as sounding like a “snorting fit” or “inhaled sneeze.” It’s different from a cough, which is usually deeper, or a choke, which may involve gagging and pawing at the mouth.

Most episodes last 15 to 30 seconds, though they can feel much longer when you’re watching your dog struggle.

Pro Tip: Try recording an episode on your phone if you’re unsure. This can help your vet rule out other conditions like coughing, choking, or a collapsing trachea.

Why Do Dogs Reverse Sneeze? (Common Causes)

Reverse sneezing is triggered when the soft palate (the area at the back of the mouth) becomes irritated or inflamed. This causes a spasm that results in that signature snort.

Here are the most common triggers of reverse sneezing:

Environmental Irritants:

• Dust, pollen, or mold
• Household cleaners, perfumes, or aerosol sprays
• Cigarette smoke or fireplace smoke

Physical Triggers:

• Excitement or sudden exertion
• Pulling on the leash (especially with collar pressure)
• Eating or drinking too quickly
• Foreign particles like grass blades or food crumbs

Breed Predispositions:

Certain dogs are simply more prone to reverse sneezing. These include:

• Brachycephalic breeds like Pugs, Bulldogs, and Shih Tzus (due to shorter nasal passages)
• Small breeds such as Yorkies, Chihuahuas, and Toy Poodles

Some dogs may experience reverse sneezing more frequently during allergy season, or in dry, dusty environments.

Important note: While reverse sneezing is usually benign, frequent or severe episodes can be a sign of something more serious, like nasal mites or an upper respiratory infection.

Is Reverse Sneezing Dangerous for Dogs?

For most dogs, reverse sneezing is not dangerous. It may look dramatic, and understandably scary, but it’s usually painless, temporary, and doesn’t interfere with your dog’s breathing long-term.

That said, reverse sneezing should still be monitored, especially if it becomes frequent or is accompanied by other symptoms. Here’s how to know when it’s normal vs. cause for concern:

Usually Normal:

• Occasional episodes that resolve in under a minute
• No change in appetite, energy, or behavior
• Happens during allergy season, after excitement, or after drinking/eating

Possible Cause for Vet Visit:

• Reverse sneezing becomes frequent or prolonged
• Your dog seems anxious or distressed after episodes
• You notice nasal discharge, coughing, wheezing, or eye goop
• Episodes are triggered by minimal activity
• Your dog has never reverse sneezed before and suddenly starts doing it often

While rare, conditions like nasal mites, polyps, foreign objects, tracheal collapse, or even infections can mimic or worsen reverse sneezing.

When in doubt, your veterinarian can perform an exam and nasal swab to rule out underlying issues.

How to Help Your Dog During a Reverse Sneezing Episode

When your dog starts reverse sneezing, the best thing you can do is stay calm. Dogs often feed off our energy, and if you panic, they may become more anxious, which can actually make the episode last longer.

Here are a few ways to help your pup during an episode:

Stay Calm & Reassure Them

Use a calm voice and gentle touch. Your presence is soothing.

Gently Massage the Throat

A light massage can help relax the soft palate and stop the spasm.

Lightly Blow on Their Nose

This can trigger a swallow reflex, which may end the episode.

Offer Fresh Water Afterward

Once it’s over, giving them water can help clear irritants from the throat.

Avoid Tugging on the Collar

If your dog tends to reverse sneeze on walks, consider switching to a harness to avoid pressure on the throat.

Most dogs act completely normal before and after an episode. If your pup returns to wagging and playing like nothing happened—you’re probably in the clear.

Dog Reverse Sneeze Treatment & Prevention

In the vast majority of cases, no medical treatment is needed for reverse sneezing. But if your dog’s episodes are frequent or clearly triggered by something, there are several ways you can help reduce how often it happens.

Reduce Exposure to Irritants:

• Avoid smoking indoors
• Don’t use strong candles, air fresheners, or sprays around your dog
• Use a HEPA air purifier during allergy seasons
• Clean bedding and vacuum regularly to remove dust and dander

Use a Harness, Not a Collar:

Pressure on the throat can trigger episodes, especially in smaller breeds.

Feed Slowly:

If reverse sneezing happens around mealtimes, try a slow feeder bowl to prevent inhaling food particles too quickly.

Treat Underlying Allergies:

Talk to your vet about antihistamines if allergies are a suspected cause. Dietary improvements may also reduce inflammation.

Feed a High-Quality Diet:

Inflammation in the respiratory tract can be worsened by low-grade kibble filled with preservatives, by-products, and additives. A clean, whole-food diet can improve your dog’s overall immune response and make them less sensitive to environmental triggers.

Chronic reverse sneezing can sometimes be reduced just by cleaning up your dog’s environment and their diet, two things you have full control over.

Breeds Prone to Reverse Sneezing

While reverse sneezing can affect dogs of any size or breed, some dogs are more prone due to their anatomy or respiratory sensitivities.

Commonly Affected Breeds:

Brachycephalic Breeds (flat-faced dogs):

• Pugs
• French Bulldogs
• Boston Terriers
• Shih Tzus
• Boxers

These breeds have shorter nasal passages and elongated soft palates, making them more likely to experience reverse sneezing, especially when overexcited or exposed to irritants.

Toy & Small Breeds:

• Chihuahuas
• Yorkshire Terriers
• Maltese
• Pomeranians

Smaller breeds have narrower tracheas and nasal cavities, which makes even mild irritants more likely to cause a reverse sneeze response.

If you share your home with one of these breeds, don’t be surprised if reverse sneezing becomes a regular, though harmless, part of life.

When to Contact Your Vet

Reverse sneezing is usually nothing to worry about—but there are times when it’s worth making a vet appointment. Here’s when to call:

Call Your Vet If:

• Episodes last longer than 1–2 minutes
• They happen daily or multiple times a week
• Your dog has trouble breathing, even outside episodes
• There’s nasal discharge, sneezing fits, or coughing
• Your dog seems lethargic, anxious, or has a change in appetite
• You notice bleeding from the nose or mouth

If your dog has never reverse sneezed before and suddenly starts, it’s always smart to get a professional opinion to rule out infections, allergies, or a foreign object lodged in the nasal cavity.

Don’t be afraid to bring a video clip to your vet—it can help immensely with diagnosis.
