If you’ve ever watched your dog suddenly extend their neck, make a loud snorting sound, and seem to gasp for air, only to be perfectly fine seconds later, you’ve witnessed reverse sneezing. Reverse sneezing in dogs is more common than most pet owners realize, and while it looks alarming, it’s rarely dangerous. This guide breaks down everything you need to know about reverse dog sneezing: what causes it, what triggers an episode, and when it’s time to call your vet.
What Is Reverse Sneezing in Dogs?
Reverse sneezing, medically called paroxysmal respiration, is the opposite of a regular sneeze. In a normal sneeze, air is rapidly forced out through the nose. During a reverse sneeze, a dog rapidly and forcefully inhales air through the nose instead. The result is a distinctive, honking, snorting, or gagging sound that can last several seconds to a minute.
Despite how distressing it looks, most dogs are completely alert during a reverse sneezing episode and return to normal almost immediately after it ends. Their color stays normal, they don’t lose consciousness, and they’re typically unfazed by the whole thing, even if their owners are not.
What Does Reverse Sneezing Look Like?
During a reverse sneezing episode, a dog typically:
- Stands still and extends or cranes their neck forward
- Pulls their elbows out or widens their stance
- Makes a loud, repeated snorting, honking, or gasping sound
- Breathes in rapidly through the nose
- Returns to normal breathing within seconds to a minute
What Causes Reverse Sneezing in Dogs?
Reverse sneezing is caused by a spasm of the muscles in the throat and soft palate. These spasms are triggered by irritation in the nasal passages, throat, or pharynx, which is the shared space at the back of the nose and mouth. The dog’s reverse sneeze is essentially an attempt to clear that irritation.
Common Triggers of Reverse Sneezing
A wide range of things can set off a reverse sneezing episode. Some of the most frequently reported triggers include:
- Excitement or physical activity: Many dogs reverse sneeze when they get worked up during play or greetings
- Eating or drinking too fast: Rapid consumption can stimulate the back of the throat
- Allergens: Pollen, dust, mold, and household chemicals can irritate nasal passages
- Strong scents: Perfumes, candles, cleaning products, or smoke
- Pulling on a collar or leash: Pressure on the throat from a collar or leash can trigger an episode
- Post-nasal drip: Drainage from allergies or upper respiratory infections
- Foreign material in the nasal passages: Grass blades, seeds, or small debris
Which Dogs Are Most Prone to Reverse Sneezing?
While any dog can experience reverse sneezing, brachycephalic breeds, meaning those with short, flat faces, are particularly prone to it. This includes breeds like Bulldogs, Pugs, Boston Terriers, Shih Tzus, and Boxers. These dogs have elongated soft palates and narrowed airways that make them anatomically more susceptible to reverse sneezing episodes. Small breeds in general also tend to experience reverse sneezing more frequently than large breeds, though the condition can occur in any dog regardless of size or breed.
Is Reverse Sneezing in Dogs Dangerous?
For the vast majority of dogs, reverse sneezing is harmless. A typical episode is brief, the dog remains fully conscious and comfortable, and normal breathing resumes on its own. Most dogs who reverse sneeze do so occasionally throughout their lives without it ever causing a health problem.
That said, there are situations where reverse sneezing can signal something more serious, particularly if episodes are becoming more frequent, more severe, or are accompanied by other concerning symptoms.
When to See a Vet About Reverse Sneezing
Contact Chimacum Valley Veterinary Hospital if your dog’s reverse sneezing:
- Occurs multiple times daily or seems to be increasing in frequency
- Is accompanied by nasal discharge, nosebleeds, or facial swelling
- Doesn’t resolve on its own within a minute or two
- Is paired with coughing, difficulty breathing, or open-mouth breathing
- Develops suddenly in a dog that has never experienced it before
- Is accompanied by loss of appetite or lethargy
These signs may indicate an underlying issue such as nasal polyps, a respiratory infection, a foreign body in the nasal passages, or a collapsing trachea, all of which require veterinary evaluation.
How Is Reverse Sneezing in Dogs Diagnosed?
In most cases, your veterinarian can identify reverse sneezing based on a description of the episodes and a physical examination. A video of the episode taken on your phone is incredibly helpful and is one of the most useful things you can bring to your appointment. The presentation is fairly distinctive, and our experienced veterinarians at Chimacum Valley Veterinary Hospital are well-practiced in distinguishing reverse sneezing from other respiratory concerns.
If your veterinarian suspects an underlying cause, diagnostics may include:
- Rhinoscopy: A camera is used to examine the nasal passages for foreign material or polyps
- X-rays: To evaluate the nasal passages and sinuses for structural abnormalities
- Bloodwork: To assess for systemic illness or allergic response
- Allergy testing: If environmental allergens are suspected
Can Reverse Sneezing Be Treated?
Because reverse sneezing is usually harmless and self-resolving, treatment is not typically required. Episodes tend to stop on their own within seconds. However, if a specific underlying cause is identified such as allergies, a foreign body, or a structural abnormality addressing that cause can reduce or eliminate the episodes.
For dogs with allergy-related reverse sneezing, your veterinarian may recommend antihistamines or other allergy management strategies. Dogs with anatomical issues, like an elongated soft palate, may benefit from a surgical procedure to improve airflow. Your veterinarian at Chimacum Valley Veterinary Hospital will tailor their recommendations based on your dog’s individual needs.
