What it is
A short muzzle does not come with a smaller set of airway parts. The nostrils can be narrow slits, the soft palate too long for the space, and the inside of the nose crowded, so every breath has to be pulled through a tight passage. Over time the constant effort can stretch and swell the soft tissues of the throat, narrowing it further.
The syndrome comes from the shape of the head, which is why it belongs to flat-faced dogs. For one dog it means noisy breathing; for another, a real struggle for air.
Heat is the big danger, because dogs cool themselves by panting and a narrow airway makes that hard. In daily life that means walks in the cool hours, shade and a calm pace rather than a long run in the afternoon sun. Excitement and extra weight also make breathing harder, so a relaxed, lean dog breathes easier.
Signs you may notice
- Loud snoring and snorting
- Tires quickly on walks
- Slow to recover on warm days
- Sleeps with chin propped up
- Gagging after eating or drinking
- Bluish tongue or gums
You may hear loud snorting or snoring even at rest, or notice that the dog tires quickly, struggles to catch their breath on a warm day, or sleeps with the chin propped up. If a dog is struggling for air, their tongue or gums turn bluish, or they collapse, see a vet immediately.
When to see a vet
If your dog is struggling to breathe, their tongue or gums look bluish, or they collapse, a vet is needed immediately. Noisy breathing or tiring easily in everyday life is worth a planned visit to talk through.
