Reverse sneezing
Picture this: You’re curled up on the sofa late at night, watching a tense horror movie. You’re already on edge—jumping at every creak of the floorboards. Suddenly, a loud, guttural, repetitive snorting sound erupts from right behind your sofa. It’s so jarring you nearly spill your popcorn. You look over, and it’s your dog: standing rigidly with their neck extended, chest heaving, making a gruesome, almost demonic noise.
Are they possessed? Choking? Having an asthma attack?
Take a deep breath. Your dog is likely just experiencing a perfectly normal, albeit terrifying-sounding, episode of reverse sneezing.
What is Reverse Sneezing?
Clinically known as paroxysmal respiration, a reverse sneeze occurs when a dog rapidly pulls air into their nose, rather than pushing it out like a normal sneeze. This involuntary reflex is triggered by irritation or inflammation in the nasal cavity, the sinuses, or the soft palate.
When the upper respiratory tract becomes inflamed, it swells and creates a tickling or restricting sensation. This triggers a spasm, causing the dog to extend their neck and forcefully inhale to try and clear the irritant. This rapid inhalation through a narrowed airway is what produces that loud, alarming snort.
The Brachycephalic Factor vs. Tracheal Collapse
While any dog can experience a reverse sneeze, it is incredibly common in small breeds and brachycephalic (flat-faced) dogs like Pugs, French Bulldogs, and Boston Terriers. Their compact facial anatomy means their soft palates are often elongated, making them highly prone to airway spasms.
However, because small dogs are also prone to a much more serious condition called Tracheal Collapse, it is vital to know the difference between the two:
| Feature | Reverse Sneezing | Tracheal Collapse |
| The Sound | Rapid, sharp inhalations; sounds like a violent snort, snarf, or rapid sniffing. | A dry, harsh, persistent noise that sounds exactly like a goose honking. |
| The Trigger | Environmental irritants, excitement, or eating/drinking too fast. | Exercise, pulling on a collar/leash, hot weather, or simply being picked up. |
| Severity | Harmless. The episode passes within a minute or two with no lasting physical effects. | A chronic, progressive, and dangerous narrowing of the windpipe requiring veterinary care. |
What Triggers the Spasms?
If reverse sneezing is harmless, what sets it off? The most common culprits are environmental irritants that tickle the back of the throat or nasal passages:
-
Allergens: Pollen, dust mites, or mold spores.
-
Household Irritants: Strong perfumes, air fresheners, smoke, or harsh cleaning products.
-
Physical Triggers: Pulling too hard on a leash, sudden bursts of excitement, or eating and drinking too rapidly.
How to Stop an Episode
Watching your dog struggle through an episode can be stressful, but the best thing you can do is stay calm. The spasm will almost always resolve itself within 30 to 60 seconds. However, if you want to help shorten the episode, you can force your dog to swallow, which physically clears the spasm in the throat.
When Is It Time to See the Vet?
For the vast majority of dogs, a reverse sneeze is a rare, isolated event—the equivalent of you getting a tickle in your throat.
However, if your dog begins having multiple, prolonged episodes every day, it’s time to book a vet appointment. Chronic reverse sneezing is usually a sign of severe underlying allergies, which can be easily managed with canine-safe antihistamines. Your veterinarian will also want to rule out other potential causes, such as a viral or bacterial respiratory infection (like Kennel Cough), nasal mites, or a foreign object (like a blade of grass or a foxtail) lodged in the nasal passage.
The next time your dog decides to do their best demon impression in the middle of a movie, you don’t need to panic. Give them a gentle throat rub, wait it out, and you can both go right back to your relaxing evening.
