TL;DR: Reverse sneezing is a common, harmless respiratory spasm triggered by throat irritation that typically resolves within a minute and does not require emergency care. Recording a video of the episode is the best way to help your veterinarian confirm it is not a more serious respiratory issue.
What causes my dog to make a sudden snorting or honking sound?
When your dog makes a sudden, rhythmic snorting or honking sound while excited, they are likely experiencing a common phenomenon known as reverse sneezing. Technically called paroxysmal respiration, this happens when the soft palate or throat becomes irritated. This irritation triggers a spasm that causes the dog to rapidly and forcefully pull air in through their nose instead of pushing it out like a normal sneeze.
Is reverse sneezing an emergency or a sign of a serious problem?
The urgency level for snorting related to excitement is generally Low. While the sound can be quite alarming—often sounding like the dog is choking or gasping for air—reverse sneezing is typically harmless. Most episodes last less than a minute, and your dog will behave perfectly normally once the spasm stops. It is not a painful condition, though your dog may look a little confused or startled by the sensation.
How does taking a video help a veterinarian triage my dog's respiratory issues?
- Record a clear video of the episode to help a veterinarian triage the situation, as these events rarely happen during a clinic visit.
- A video allows the professional to observe specific respiratory sounds and body language.
- Visual documentation helps distinguish harmless reverse sneezing from serious conditions like a collapsing trachea or a nasal foreign object.
Clinical Context (Merck Veterinary Manual)
Aspiration reflex, commonly known as "reverse sneeze," is a short, paroxysmal episode of inspiratory effort intended to clear the nasopharynx of obstructing material and is frequently seen in dogs. Mild excitement can elicit snorting, which may occur several times a day and can be accompanied by lip smacking and nasal discharge. *Pneumonyssoides caninum* infection in dogs can also cause reverse sneezing, along with other nonspecific upper respiratory signs such as sneezing, rhinitis, impaired scenting ability, and pawing at the muzzle.
