What Is Reverse Sneezing in Dogs? A Complete Guide for Concerned Pet Parents
If your dog suddenly begins making loud snorting or honking sounds, it can be alarming — especially the first time it happens. Many owners worry their dog is choking or struggling to breathe. But in most cases, this strange behavior is something far less dangerous: reverse sneezing. It’s more common than you might think, and once you understand what’s happening, the episodes become much less frightening.

What Is Reverse Sneezing?
Reverse sneezing is a reflex where your dog rapidly pulls air in through their nose, creating a snorting or gasping sound. During an episode, your dog may:
-
stand still with elbows apart
-
stretch their neck
-
inhale repeatedly with a rhythmic, loud snort
-
appear momentarily tense
Despite looking dramatic, reverse sneezing is usually short, harmless, and painless. It happens when the soft palate or throat becomes irritated, causing a brief spasm. Think of it as the opposite of a regular sneeze — instead of pushing air out, your dog pulls air in.
Why Does Your Dog Reverse Sneeze?
Reverse sneezing can look dramatic, but the reasons behind it are usually simple and harmless. Understanding what triggers these episodes can help you stay calm and better support your dog when it happens. Here are the most common causes:
-
Irritants such as dust, pollen, or perfume Small particles in the air can tickle the throat or nasal passages, leading to a sudden episode. Many dogs are especially sensitive during seasonal changes, which makes this a frequent trigger.
-
Excitement or overstimulation Some dogs reverse sneeze when they get overly excited, greeting you at the door or during play. High-energy moments can temporarily disrupt their breathing rhythm, making an episode more likely.
-
Temperature or humidity changes Going from warm indoors to chilly outside (or the reverse) can irritate the airway. Sudden environmental shifts can cause brief swelling in the soft palate that leads to reverse sneezing.

Pulling on the leash Pressure on the throat can trigger a spasm, especially in small or flat-faced breeds. Switching to a harness often reduces these episodes by protecting the neck area.
-
Breed tendencies Breeds like Shih Tzus, Pugs, Yorkies, Beagles, and other small dogs experience it more often due to their anatomy. Their smaller airways and longer soft palates make them naturally more prone to these reflexes.
Reverse sneezing rarely indicates a serious health issue, but knowing the triggers helps you stay attentive and respond with confidence. With a little awareness, you can support your dog through episodes without worry.
How to Stop Reverse Sneezing
Most episodes end quickly, but if your dog seems uncomfortable, a few gentle techniques can help them recover more easily. Here’s how to support them during an episode:
-
Stay calm Your reaction reassures your dog, helping them relax instead of becoming anxious. Dogs often mirror your emotions, so speaking softly or offering gentle touch can ease their tension.
-
Gently stroke or massage the throat This movement encourages your dog to swallow, which often helps reset their breathing and stop the reflex. Slow, soothing motions work best, especially for nervous or small breeds.
-
Briefly cover the nostrils Covering the nose for just a second or two prompts a swallow that interrupts the spasm. Be gentle and quick — this should never feel forceful or uncomfortable for your dog.

Move your dog away from irritants Smoke, perfume, cleaning sprays, or dusty areas may trigger an episode. Creating a clean, irritant-free environment — and keeping your dog in soft, protective clothing during windy or dusty days — reduces exposure and helps prevent recurrences.
-
Use a harness instead of a collar Reducing neck pressure helps prevent throat irritation during walks, especially in small or flat-faced breeds prone to reverse sneezing. A well-fitted harness paired with comfortable dog clothes can make outings gentler on their airway.
These small steps make episodes shorter and help your dog recover calmly, giving you both more confidence when reverse sneezing occurs.
When to See a Vet
Reverse sneezing is usually harmless, but there are times when veterinary guidance is important. You should contact your vet if episodes last longer than a minute, become more frequent or intense, or if your dog shows additional symptoms such as nasal discharge, coughing, or difficulty breathing. It’s also worth reaching out if your dog appears distressed during an episode, struggles to recover normally, or if the behavior begins suddenly in an older dog. Any suspicion of allergies, infection, or a foreign object in the nose should also be checked. A veterinarian can rule out uncommon but possible conditions — such as nasal mites, infections, tracheal issues, or an elongated soft palate — and help ensure your dog stays comfortable and healthy.
What to Remember About Reverse Sneezing
Reverse sneezing may look dramatic, but it’s usually just a harmless reflex that many dogs experience throughout their lives. Once you know what’s happening, it becomes easier to stay calm, help your dog through the moment, and recognize when something more serious might be going on. With gentle support, awareness of triggers, and routine veterinary care, you can keep your dog comfortable and confident — even during those noisy, unexpected snorts.
