Small Nostrils (stenotic Nares) in Newfoundlands
Quick answer
Does stenotic nares apply to this breed?
No. It is a brachycephalic condition that does not occur in this long-muzzled breed.
A short nose and a long nose fail in genuinely different ways, and this breed's real nasal risks are almost the mirror image of the ones the search term you started with describes.
For owners who noticed nasal discharge, sneezing, nosebleeds or a change in breathing sound, searched for narrowed nostrils, and found a condition clearly built for a different kind of face, and now want to know what to actually watch for instead.

What this problem looks like
Stenotic nares, congenitally narrowed nostrils, is a brachycephalic condition that does not apply to the Newfoundland's long, proportionate muzzle and has not been documented in this breed. The nasal risks genuinely relevant here run in nearly the opposite direction: comparative research links longer nasal passages with a higher relative risk of nasal tumours, and this breed's outdoor, vegetation-and-water-heavy lifestyle creates real exposure to inhaled foreign bodies, alongside the general possibility of chronic rhinitis from infection or dental disease.
Common triggers
- A long nasal passage with more lining exposed to inhaled irritants over a dog's lifetime
- Outdoor activity through vegetation, undergrowth or water increasing exposure to inhaled foreign material
- Dental disease affecting a tooth root close to the nasal cavity
- Fungal or bacterial infection of the nasal lining
- Age, since nasal tumours and chronic nasal disease both become more likely in older dogs
Stenotic nares itself does not occur in this breed and is not a relevant risk. Nasal tumours and nasal foreign bodies are not among the five conditions most consistently documented for the Newfoundland, which are hip dysplasia, subaortic stenosis, dilated cardiomyopathy, cystinuria and bloat, but comparative research consistently finds long-nosed breeds at higher relative risk of nasal tumours than short-nosed breeds, and this breed's lifestyle creates genuine, regular exposure to inhaled foreign material.
Why this happens
Breed factors
This breed's long, mesocephalic muzzle rules out the anatomical crowding behind stenotic nares, so that specific mechanism is simply not relevant here. What the breed's long nasal passage does contribute is more total lining exposed to whatever the dog breathes in across its lifetime, which comparative veterinary research associates with a higher relative risk of nasal tumours than in short-muzzled breeds. This breed's enthusiastic, exploratory relationship with water, mud, undergrowth and leaf litter also means its nose spends more time in direct contact with the kind of debris that becomes a lodged foreign body than a more sedentary or indoor-living breed's would.
Environment factors
Environment is the dominant factor behind foreign-body risk specifically: dense vegetation, leaf litter, silty water and digging all put material directly in the path of an inquisitive nose. Dental disease left unaddressed can eventually affect nearby nasal structures, making regular dental care an indirect but genuine protective factor. Long-term exposure to environmental irritants, though not something an individual household can fully control, is part of the general backdrop against which nasal tumour risk in long-nosed breeds is discussed in veterinary literature.
What you can do at home (once it is not an emergency)
When to talk to your vet
Book a same-day appointment for sudden intense sneezing with one-sided nasal discharge, especially following outdoor activity, since a lodged foreign body causes ongoing irritation the longer it remains in place. Book promptly for discharge lasting more than a week, discharge that becomes blood-tinged, any facial swelling or asymmetry, or an unexplained nosebleed. General discharge from both nostrils alongside overall unwellness also warrants a veterinary visit rather than home monitoring alone.
At home, alongside your vet's plan
- Watch for sudden, intense sneezing with one-sided discharge after outdoor activity, which is the classic pattern of a freshly lodged foreign body.
- Note whether nasal discharge is from one side or both, and whether it is clear, thick, or blood-tinged, since this pattern is genuinely useful diagnostic information.
- Keep up with regular dental care, since untreated dental disease can eventually involve nearby nasal structures.
- Photograph the face from directly in front if you notice any swelling or asymmetry, so a vet can judge change over time.
- Do not attempt to remove a suspected foreign body from deep in the nasal passage yourself, since this risks pushing it further in or causing injury.
- Treat any unexplained nosebleed as worth a veterinary visit rather than assuming it is minor, particularly in an older dog.

What to expect, and how you know it is working
A nasal foreign body, once identified and removed, typically resolves within days, with sneezing and discharge settling quickly afterward. Chronic rhinitis from infection generally responds to treatment over several weeks, though some cases require ongoing management. A confirmed nasal tumour carries a more serious and individually variable outlook depending on the specific type and how early it was found, and is a conversation best had directly with a veterinary oncologist once imaging and biopsy results are available.
Success is a nose that breathes and drains normally, free of persistent one-sided discharge, sneezing fits or unexplained bleeding, and an owner who has learned to read the pattern of nasal signs well enough to know which ones warrant same-day attention. It is not the elimination of ordinary snoring, which is a normal feature of this breed's thick neck and soft tissue rather than a sign of nasal disease.
The Risks That Actually Come With a Long Nose
A long nasal passage has more surface area lining it than a short one, and that lining is what filters and processes every breath of air a dog takes over its lifetime. Comparative veterinary research into nasal disease has repeatedly found that longer-nosed, dolichocephalic and mesocephalic breeds carry a higher relative risk of nasal tumours than short-muzzled breeds, essentially the opposite pattern from the airway obstruction risk that dominates brachycephalic conversations. More lining exposed to inhaled particles and irritants over more years appears to translate into more opportunity for abnormal cell growth to take hold somewhere along that passage.
Foreign material is the second major nasal risk, and it is almost entirely a lifestyle issue rather than an anatomical one. A dog that swims, digs, noses through leaf litter and pushes its face into undergrowth, which describes most Newfoundlands most weeks of the year, has real opportunities to inhale a grass awn, a splinter of wood, or a piece of plant material up into the nasal passage. Once lodged, these are notoriously irritating and can cause a sudden bout of intense sneezing, one-sided discharge, and pawing at the nose that looks alarming and usually is worth same-day attention.
Chronic nasal discharge and inflammation, sometimes grouped as rhinitis, is the third category, and it can stem from a lingering foreign body, a fungal infection acquired from environmental exposure, dental disease affecting a tooth root near the nasal cavity, or an underlying growth. None of these are the same problem, and distinguishing between them, usually through imaging and sometimes a scope passed into the nasal passage under anaesthesia, is what actually determines the treatment path, which is a very different diagnostic process from anything involved in stenotic nares.
Sorting the Warning Signs by What They Usually Mean
Nasal signs in dogs are genuinely diagnostic when read carefully, and the pattern matters more than any single symptom in isolation.
- Sudden, intense sneezing fits with discharge from one nostril only, especially after a walk through vegetation or a swim: strongly suggests a lodged foreign body and warrants same-day veterinary attention.
- Gradual, one-sided discharge that has gone on for weeks, especially if it becomes blood-tinged or the face over that side of the nose looks subtly swollen: raises the question of a growth and deserves imaging sooner rather than later.
- Discharge from both nostrils, sneezing, and general unwellness: points more toward an infectious or inflammatory cause rather than a growth or foreign body, though it still needs proper veterinary assessment.
- Nosebleeds without an obvious cause such as trauma: should never be dismissed as trivial in an older dog and are one of the more concerning signs on this list.
- Snoring or noisy breathing during sleep with no other signs at all: usually reflects normal soft tissue bulk in a heavy-headed, thick-necked breed rather than a nasal disease process, and is generally not a cause for alarm on its own.
- Noisy or laboured breathing specifically while the dog is awake and active, rather than only while sleeping, is a different concern involving the throat rather than the nose, and is covered separately from this page.
- Any nasal sign accompanied by facial asymmetry, one eye looking different from the other, or reduced appetite deserves prompt imaging rather than a wait-and-see approach.
The Sneezing Fit That Was Never About the Nostrils
Fable came home from a lakeside walk through tall reeds and, within the hour, launched into a violent sneezing fit unlike anything her owner, Ines, had seen from her before, pawing repeatedly at one side of her face with clear discharge running from that same nostril. Ines had, months earlier, read about narrowed nostrils in flat-faced breeds after noticing Fable snored loudly some nights, and had filed the information away as not quite relevant to her long-nosed dog. Faced with this new, dramatically different symptom, she called her vet the same afternoon rather than waiting to see if it settled. Under light sedation, the vet located and removed a grass seed lodged well up into Fable's nasal passage, almost certainly picked up while she pushed her nose through the reeds. The sneezing and discharge stopped within a day of the seed's removal. It was, Ines later realised, a completely different problem from the snoring she had once worried about, and had nothing at all to do with the nostril anatomy she had originally researched.
Key takeaway: Sudden, one-sided sneezing and discharge after time outdoors is a foreign-body pattern worth same-day attention, and it has nothing to do with nostril width. Timing and which side is affected tell you far more than the search term you start with.
Frequently asked questions
Do Newfoundlands get stenotic nares?
No. This is a congenital nostril narrowing specific to brachycephalic, short-muzzled breeds, and it has not been documented in Newfoundlands, whose long muzzle does not produce the anatomical crowding behind the condition.
Why would a long-nosed breed have a higher nasal tumour risk than a short-nosed one?
Comparative research suggests more nasal lining exposed to inhaled irritants over a longer passage may translate into more opportunity for abnormal cell growth over a dog's lifetime, the opposite pattern from the airway crowding problems that dominate in short-muzzled breeds.
How can I tell a foreign body from something more serious?
Timing is the best clue. A sudden, dramatic onset of sneezing and one-sided discharge right after outdoor activity strongly suggests a foreign body. A slower, weeks-long build-up, especially with blood-tinged discharge or facial swelling, points more toward a growth and needs prompt imaging rather than assuming it will pass.
Is snoring in this breed something to worry about?
Generally not on its own. This breed's thick neck and generous soft tissue commonly produce snoring during sleep without any underlying disease. Noisy breathing while awake and active is a different and more relevant concern, related to the throat rather than the nose.
How is a suspected nasal foreign body or tumour actually diagnosed?
Usually through imaging such as a CT scan, sometimes combined with a scope passed into the nasal passage to directly visualise and, where possible, retrieve a foreign body or take a biopsy. This typically requires general anaesthesia, which raises the usual cardiac screening conversation in this breed beforehand.
Are nosebleeds ever normal?
Not without an obvious cause such as a recent minor injury. An unexplained nosebleed, particularly in an older dog, should always be investigated rather than assumed to be trivial, since it can be an early sign of several serious underlying conditions.
