Small Nostrils (stenotic Nares) in Chow Chows
Quick answer
What does a healthy nostril look like on a Chow Chow?
A reasonably round opening that visibly widens during exertion rather than staying pinched into a narrow slit.
Two nostrils can look similar at a glance and behave very differently the moment a dog starts breathing hard. Pinched nares that barely flare during exertion are doing far less work than they should.
Owners trying to work out whether their Chow's noisy breathing comes from the nose, the throat, or somewhere else, and anyone told that surgery might help but unsure what part of the airway it would actually address.

What this problem looks like
Stenotic nares is a narrowed nostril opening caused by soft, collapsible cartilage at the front of the nose, distinct from throat-based airway restriction. It is one specific, visually identifiable contributor to breathing limitation reported in the breed's moderately shortened, broad head, and it can often be assessed by direct observation before any vet visit.
Common triggers
- Individual variation in nostril cartilage firmness and opening size, which varies considerably even within the breed
- Exertion or excitement, which reveals how well the nostrils actually flare open under demand
- Warm weather, which raises the airflow the dog needs at exactly the moment the restriction matters most
- Weight gain, which adds general respiratory demand on top of an already narrowed opening
- Excitement-driven panting, which further reveals whether the nostrils can open fully or not
Nostril width is reported to vary considerably between individual Chow Chows and breed lines. Not every dog with a moderately shortened muzzle has clinically narrow nares, but it is a frequently checked and sometimes surgically addressed feature within the breed's broader airway conversation.
Why this happens
Breed factors
The Chow's moderately broad, shortened skull compresses the soft tissue and cartilage structures of the face into less space than a longer-muzzled dog has, and the cartilage supporting the nostril opening can be soft and prone to collapsing inward rather than flaring open properly under airflow demand. This is a structural, mechanical issue at the front of the nose, separate from soft tissue further back in the throat.
Environment factors
Heat, humidity, excitement and exertion all increase how much air the dog needs to move through the nose, and it is precisely under those conditions that a narrowed opening becomes a genuine limitation rather than a cosmetic detail.
What you can do at home (once it is not an emergency)
When to talk to your vet
Get a vet evaluation if the nostrils consistently stay pinched during exertion, if breathing sounds notably labored or noisy at rest, or if your dog struggles to cool down normally after mild activity, since these suggest a restriction significant enough to warrant discussing correction.
At home, alongside your vet's plan
- Watch the nostrils at rest and during mild exertion, noting whether they flare open or stay pinched
- Keep a note of any snorting or noisy breathing that seems to originate at the front of the nose specifically
- Avoid intense exercise or hot conditions until a suspected restriction has been evaluated by a vet
- Keep your dog at a lean weight, since extra weight adds respiratory demand on top of any existing restriction
- Photograph or video the nostrils during exertion to show your vet a clear before-and-after reference

What to expect, and how you know it is working
Recovery from alarplasty surgery typically takes one to two weeks before a dog is back to full normal activity, with breathing improvement often noticeable soon after the initial swelling resolves.
Success is nostrils that visibly widen appropriately during exertion and breathing that sounds clearer during activity, not necessarily complete silence, since some individual variation in breathing sound is normal even after correction.
A Simple Way to Check This Yourself
This is not a substitute for a vet exam, but it gives you a concrete before-and-after to describe, and it separates a front-of-nose problem from a back-of-throat one, which matters for figuring out what, if anything, needs fixing.
- Watch the nostrils at rest first, noting whether the openings look like small slits or reasonably round holes
- Then watch during or right after mild exertion, such as a short trot, and see whether the nostrils flare open wider or stay collapsed
- A nostril that stays pinched shut during effort, rather than opening to pull in more air, is the visual sign of true stenotic nares
- Compare side to side, since one nostril can be more affected than the other
- Note any snorting, sneezing or reverse-sneezing episodes that seem to originate right at the front of the nose rather than deeper in the throat
Why the Surgical Fix Here Is Narrower Than People Expect
Correcting stenotic nares alone is a relatively contained procedure called an alarplasty, which removes a small wedge of the collapsible cartilage to widen the permanent opening. It is not the same operation as soft palate resection, and a dog whose main issue is genuinely at the nostril, rather than further back in the throat, can sometimes see a real improvement in breathing effort from this one procedure without needing the larger combined airway surgery some Chows eventually require.
The practical value of identifying stenotic nares specifically, rather than lumping every noisy-breathing symptom together, is that it lets a vet target the actual restriction rather than assuming the whole airway needs to be addressed at once.
The Nostril Test That Settled the Question
Loki's owner Tobias had read conflicting advice about whether his snoring, broad-headed Chow needed airway surgery, and two vets had given him slightly different impressions during routine visits. On a friend's suggestion, Tobias filmed Loki's nose during a short trot in the yard and noticed the nostrils barely moved at all, staying pinched into thin slits even as Loki's breathing audibly picked up. He brought the video to a veterinary specialist, who confirmed significant stenotic nares as the primary restriction, with the rest of Loki's airway looking reasonably proportioned for the breed. Rather than the full combined airway surgery Tobias had been bracing for, Loki had a standalone alarplasty. Within two weeks of recovery, Tobias noticed Loki's nostrils flaring properly during play for what he realized was the first time he had actually looked closely enough to notice.
Key takeaway: Not every noisy-breathing Chow needs the largest possible surgery. Watching specifically how the nostrils behave under exertion can identify a narrower, more targeted problem and a narrower fix.
Frequently asked questions
How do I know if my Chow Chow has stenotic nares specifically?
Watch the nostrils during mild exertion. If they stay pinched and narrow rather than flaring open to pull in more air, that is the visual hallmark of stenotic nares as opposed to a throat-based airway problem.
Is stenotic nares the same thing as an elongated soft palate?
No. Stenotic nares is a narrowed opening at the front of the nose caused by collapsible cartilage. An elongated soft palate is excess tissue further back in the throat. Both can contribute to airway restriction, but they are separate structures with separate fixes.
Can stenotic nares be fixed without a bigger airway surgery?
In some dogs yes, if the nostril opening is the primary restriction rather than one part of a larger combined problem. An alarplasty addressing the nostril alone can meaningfully improve breathing in that case.
At what age is alarplasty usually performed?
It is often done while a dog is young, sometimes at the same time as a spay or neuter, though it can be performed at any age once the restriction is confirmed to be significant.
Will my Chow Chow definitely need this surgery?
Not necessarily. Nostril width varies between individual Chows, and a dog with reasonably open nares at rest and during exertion may never need surgical correction.
Does snoring mean my Chow Chow has stenotic nares?
Not specifically. Snoring more often points toward soft palate or throat tissue rather than the nostril opening itself, so it is one clue among several rather than a direct sign of this particular problem.
How much does alarplasty typically cost?
As a standalone procedure it commonly runs several hundred to around a thousand dollars, though cost rises if it is combined with soft palate surgery in the same anaesthetic.
What are the signs of small nostrils (stenotic nares) in Chows?
The early signs are set out in the sections above, and they are the reason to book a veterinary appointment rather than wait. Small Nostrils (stenotic Nares) in Chows is diagnosed by a vet, not from a symptom list, and the sooner it is on record the more options remain open.

Is stenotic nares surgery painful for the dog?
Recovery involves some swelling and discomfort managed with pain control, and most dogs are back to normal activity within one to two weeks.
Living
Can I check for this at home before a vet visit?
Yes, watching nostril movement at rest and during light exertion gives useful information to describe to your vet.
Health
Does this condition get worse with age?
The cartilage restriction itself is typically present from a young age rather than progressive, though secondary airway strain can build over time if left unaddressed.
Training
Should I avoid intense exercise if my Chow Chow has narrow nostrils?
Yes, until it is evaluated, since a dog with limited nostril airflow can tire and overheat faster than expected on exertion.
