If you’ve ever heard your dog make a sudden snorting or honking sound that seems alarming but ends quickly, you’ve likely witnessed a reverse sneeze. Unlike a regular sneeze that pushes air out, reverse sneezing is a rapid inhalation that can sound intense—but it's usually harmless. It often happens due to throat irritation, allergies, excitement, or even pulling on a leash. Most episodes last less than a minute and don’t require treatment. However, if reverse sneezing becomes frequent or is accompanied by other symptoms, it's worth checking in with a veterinarian.
