Small Nostrils (stenotic Nares) in Chinese Shar-Peis
Quick answer
What causes narrow nostrils in this breed?
Softer or differently positioned cartilage allows the nostril walls to collapse inward during breathing, physically restricting the opening.
Sometimes the whole airway system downstream is perfectly fine, and the actual bottleneck is sitting right at the tip of the nose.
Owners of Shar-Pei puppies with visibly pinched or slit-like nostrils, and anyone noticing loud snorting, snoring, or open-mouth breathing at rest rather than only during exercise.

What this problem looks like
Stenotic nares is a structural narrowing of the nostril openings themselves, where softer or differently positioned cartilage causes the nostril walls to collapse inward during inhalation. It's a distinct, specific component of the Chinese Shar-Pei's broader airway restriction, and while mild cases may need no intervention, dogs with real functional breathing distress often benefit meaningfully from a straightforward surgical correction.
Common triggers
- Softer or differently structured nostril cartilage from birth
- The breed's characteristic facial wrinkling around the muzzle
- Exertion or excitement increasing breathing demand
- Hot or humid weather compounding airflow restriction
- Excess weight adding further strain to an already limited airway
Stenotic nares is a recognized structural trait within this breed's broader airway profile, occurring in a meaningful subset of individual dogs rather than being universal, making visual and auditory screening for it a reasonable part of routine puppy exams.
Why this happens
Breed factors
The Chinese Shar-Pei's characteristic facial wrinkling and moderately shortened muzzle physically affect nostril cartilage support and positioning in some individual dogs, creating the structural narrowing that defines stenotic nares as distinct from the breed's broader airway restriction.
Environment factors
Hot weather, humidity, exertion, and excitement all increase breathing demand, and in a dog with structurally narrowed nostrils, that increased demand is exactly what exposes the restriction as a functional problem rather than a purely cosmetic one.
What you can do at home (once it is not an emergency)
When to talk to your vet
Schedule an evaluation for visibly pinched nostrils accompanied by snoring while awake, open-mouth breathing at rest, or noticeable breathing effort during normal activity. Sudden severe breathing distress, bluish gums, or collapse requires emergency care immediately.
At home, alongside your vet's plan
- Examine your Shar-Pei's nostrils at rest, looking for narrow vertical slits rather than open, oval-shaped openings.
- Listen for snorting, snoring while awake, or a honking sound during exertion and note how often it occurs.
- Keep exercise moderate during hot weather, since heat compounds any existing airflow restriction.
- Maintain a lean body weight to avoid adding further strain to an already limited breathing capacity.
- Discuss any concerning nostril shape or breathing sound with your vet at a routine visit rather than waiting for a crisis.

What to expect, and how you know it is working
Diagnosis is usually straightforward through visual exam at a routine puppy or adult visit. If surgery is recommended, it's typically a same-day outpatient procedure with a short recovery period of about one to two weeks.
Success looks like noticeably easier, quieter breathing at rest and during exercise following surgical correction, or, for milder cases managed without surgery, stable breathing that doesn't progress to significant functional distress over time.
What Narrow Nostrils Actually Look and Sound Like
A dog with normal nostril structure has openings that stay reasonably wide even during a deep inhale. With stenotic nares, the cartilage supporting the nostril walls is softer or positioned differently than it should be, and each inward breath actually pulls the nostril walls further inward instead of holding them open, functionally narrowing the passage right when the dog needs air most. Visually, this often looks like nostrils that appear as thin vertical slits rather than open ovals, sometimes with visible flaring or effort around the nose during normal breathing. The sounds that go with it, snorting, snoring even while fully awake, or a soft honking noise during exertion, are frequently loud enough that owners notice the sound well before they think to examine the actual shape of the nostrils causing it.
Deciding Whether Surgical Widening Is Worth It
A relatively minor outpatient procedure can widen the nostril openings by removing a small wedge of tissue from each side, immediately increasing how much air can pass through with each breath. This isn't automatically recommended for every Shar-Pei with mildly narrow-looking nostrils, since some dogs compensate well enough that surgery isn't worth the anesthesia risk for a cosmetic-adjacent improvement. The clearer case for surgery is a dog showing real functional signs, audible distress breathing at rest, exercise intolerance clearly tied to breathing rather than joints or heart, or open-mouth breathing that persists even in a calm, cool room. Because this breed also carries its own separate list of anesthesia considerations, any recommended nares surgery is worth discussing specifically in terms of anesthetic protocol with a vet familiar with this breed's broader airway and skin profile, not treated as a routine, one-size-fits-all outpatient procedure.
Ollie's Noisy Naps
Ollie, a Shar-Pei puppy in Spokane, snored loudly enough during naps that his owner initially found it endearing, until she noticed he was making similar sounds while fully awake and resting quietly on the couch. A vet exam revealed distinctly narrow, slit-like nostrils, and Ollie was also showing mild open-mouth breathing even in a cool, calm room. Given these functional signs rather than just an unusual look, his vet recommended surgical widening. The outpatient procedure went smoothly, and within two weeks of recovery, Ollie's breathing at rest was noticeably quieter, and his naps stopped sounding like a workout.
Key takeaway: The detail that tipped things toward surgery wasn't how Ollie's nostrils looked, it was that he was working to breathe even at complete rest, the functional distress that separates a cosmetic quirk from a genuine airway bottleneck.
Frequently asked questions
What exactly are stenotic nares?
It's a structural narrowing of the nostril openings themselves, where softer or differently positioned cartilage allows the nostril walls to collapse inward during inhalation, physically restricting airflow right at the entry point.
How can I tell if my Shar-Pei has this condition?
Look for nostrils that appear as narrow vertical slits rather than open ovals, along with snorting, snoring while awake, or visible effort and flaring around the nose during normal breathing.
Is this the same as being brachycephalic?
It's related but more specific, this breed has some brachycephalic-adjacent traits overall, and stenotic nares is one particular structural component of that broader picture, focused specifically on the nostril openings themselves.
Does every Shar-Pei with narrow-looking nostrils need surgery?
No, some dogs compensate well and don't show real functional breathing distress, in which case surgery may not be worth the anesthesia exposure. Dogs with audible distress at rest or clear exercise intolerance are stronger surgical candidates.
What does the surgical correction involve?
It's a relatively minor outpatient procedure removing a small wedge of tissue from each nostril to widen the opening, typically improving airflow immediately once healed.
Is anesthesia riskier for this specific procedure in this breed?
This breed has its own broader anesthesia considerations tied to its skin and airway traits, so any nares surgery should involve a vet familiar with those specifics rather than being treated as a routine, low-risk anesthetic case.
Can stenotic nares get worse over time if untreated?
The structural narrowing itself doesn't necessarily worsen, but compensating for restricted airflow puts ongoing extra strain on the rest of the respiratory system, which can contribute to broader breathing difficulty over time if left uncorrected in a significantly affected dog.

What does this condition sound like?
Snorting, snoring while fully awake, or a soft honking noise during exertion are common, often noticed before the nostril shape itself is examined.
Health
Is surgery always needed?
No, only dogs showing real functional distress, like breathing effort at rest or exercise intolerance, are typically strong surgical candidates.
Costs
How much does nares surgery cost?
It's a relatively minor outpatient procedure, generally a moderate expense including anesthesia and the surgery itself.
Training
Should I mention this to my vet before any anesthesia?
Yes, this breed's airway and skin traits are relevant anesthesia considerations worth discussing specifically before any sedation, not just for nares surgery.
