These four things get filmed and sent to veterinary practices constantly, because from a few feet away they can sound similar and one of them is frightening to watch. Telling them apart is mostly about the direction of the air and what the dog is like immediately afterwards.
The four patterns
| What | Sounds like | Direction | Afterwards |
|---|---|---|---|
| Reverse sneeze | Rapid snorting, honking inward, elbows braced, neck extended | Air rushing in | Completely normal within a minute |
| Cough | A single or repeated push, sometimes ending in a gag or swallow | Air pushed out | Usually normal, may repeat through the day |
| Honking airway noise | A goose like honk, often on excitement, drinking or collar pressure | Out, on exertion | Settles when the dog settles, recurs predictably |
| Breathing difficulty | Often quiet. Effort is visible rather than audible | Both, with effort | Does not resolve. Worsens. |
The last row is the one that matters and the one least likely to make a dramatic noise. Look at the belly and the elbows rather than listening. Abdominal effort, elbows held away from the chest, an extended neck, reluctance to lie down, or gums that are blue, gray or very pale mean going now.
What to film, and what to write down
- A short video from the side, showing the whole dog rather than the face, so the chest and abdomen are visible
- How long the episode lasted
- What was happening immediately before: excitement, drinking, eating, exercise, waking up, lead pressure
- How the dog was thirty seconds afterwards
- How often it happens and whether that is increasing
That video is genuinely useful. Practices see these described far more often than observed, and thirty seconds of footage frequently settles the question in the consultation.
When a reverse sneeze stops being reassuring
Occasional reverse sneezing in an otherwise well dog is not usually a concern. It is worth an appointment if the episodes are becoming more frequent or longer, if they started recently in an older dog, if there is nasal discharge or bleeding, if the dog is losing weight, or if anything about the pattern has changed.
A honking noise associated with collar pressure is worth raising too, and switching to a harness in the meantime is sensible regardless of the eventual answer.
