Dog Reverse Sneezing: What It Is & When to Worry

Your dog suddenly starts making a rapid, loud snorting sound — like they're inhaling a sneeze over and over. It sounds terrifying, like the dog can't breathe. This is reverse sneezing, and it's almost always harmless.

What Is Reverse Sneezing?

Technically called paroxysmal respiration — a spasm of the soft palate and throat. During a normal sneeze, air is forced OUT through the nose. During a reverse sneeze, the dog rapidly pulls air IN through the nose, producing a distinctive honking, snorting sound. The dog extends their neck, stands still, and makes a repetitive "snork" noise that lasts 10-30 seconds. It looks much scarier than it is.

What Causes It?

Irritation of the nasal passages or throat: allergies (pollen, dust), excitement or exercise, pulling on a collar/leash (pressure on the throat), eating or drinking too fast, nasal mites (rare), nasal foreign body (grass awn), and post-nasal drip from dental disease.

Small and brachycephalic breeds (Pugs, Bulldogs, Boston Terriers) are more prone due to their elongated soft palate.

How to Stop an Episode

Gently massage the dog's throat to relax the spasm. Briefly cover the nostrils — this forces the dog to swallow, which stops the spasm. Offer water. Stay calm — your anxiety makes the dog more anxious. The episode usually resolves on its own within 30 seconds.

When to See a Vet

Episodes lasting more than 1-2 minutes, episodes happening multiple times daily, nasal discharge (especially yellow/green or bloody), sneezing (regular or reverse) that started suddenly (possible foreign body), dog seems distressed or can't breathe between episodes, or accompanying coughing, gagging, or retching.

When It's NOT Reverse Sneezing

Tracheal collapse — honking goose cough, older small breeds, triggered by excitement. Kennel cough — productive cough, retching, white foam. Respiratory distress — open-mouth breathing, blue gums, unable to catch breath. These are emergencies.

Reverse sneezing videos on YouTube look dramatic but the dog is breathing normally the whole time. If your dog acts fine before and after the episode, it's almost certainly reverse sneezing.
