Respiratory Disease in Shetland Sheepdogs
Quick answer
Do Shelties have breathing problems?
Not the flat-faced kind. Their long muzzle protects them from that entirely. Their respiratory problems are throat irritation, nasal foreign bodies and infection.
A long nose brings its own problems, and two of them are shaped directly by how this breed lives: it barks constantly, and it puts its face into long grass.
Owners of a Sheltie with a persistent cough or noisy breathing who have found a great deal of information about bulldogs and pugs and none of it applies.

What this problem looks like
Respiratory problems in Shetland Sheepdogs have nothing to do with the flat-faced airway syndrome that dominates writing on the subject. This breed has a long muzzle and a full nasal chamber. Its actual issues are chronic upper airway irritation in a dog that barks constantly and pulls on a collar, inhaled grass seeds in a dog that hunts with its nose in long vegetation, and the ordinary infectious coughs any dog can catch.
Common triggers
- Flat collar pressure on the throat in a vocal dog that pulls toward what it is barking at
- Sustained barking itself, which loads the larynx and upper airway
- Grass awns and seed heads inhaled while quartering long vegetation
- Infectious respiratory disease picked up at classes, shows and boarding kennels
- Heat and humidity in a heavily coated dog, which increase respiratory effort
Collar-related cough is very common in this breed and very commonly misattributed. Grass awns are a seasonal problem concentrated in summer and autumn. Serious nasal disease is uncommon but is over-represented in long-muzzled breeds, and any one-sided nasal sign should be taken seriously rather than treated empirically.
Why this happens
Breed factors
Two breed traits drive almost everything on this page and neither is anatomical in the way owners expect. The first is vocalisation: the Shetland Sheepdog is exceptionally barky, and a dog that barks hard while straining against a flat collar irritates its own upper airway repeatedly. The second is the long, narrow muzzle, which spares the breed the compressed-airway problems of flat-faced dogs but leaves a long nasal chamber open to inhaled plant material and to the fungal and neoplastic conditions that favour dolichocephalic breeds. MDR1 drug sensitivity is the third consideration, because retrieving a nasal foreign body means sedation.
Environment factors
Equipment and terrain do most of the work. A flat collar on a pulling, barking dog is the single most modifiable factor. Long grass and stubble fields in summer are where awns are inhaled, and a dog that works with its nose down is far more exposed than one that trots on a path. Communal environments such as training classes, shows and kennels are where infectious coughs are acquired, which matters for a breed whose owners tend to be active in dog sports.
What you can do at home (once it is not an emergency)
When to talk to your vet
Go immediately, as an emergency: breathing that is laboured at rest, gums that look blue or grey, a dog standing with elbows out and neck extended, choking or collapse, or a cough so severe the dog cannot rest. Same day: a sudden violent sneezing fit that started outdoors, blood or discharge from one nostril, a face the dog is pawing at, or noisy breathing that has come on abruptly. Within a week: a persistent cough that has not improved after switching to a harness, a wet cough in an older dog, exercise intolerance with increased respiratory effort, or discharge from both nostrils that has lasted more than a few days. Mention MDR1 whenever sedation is likely.
At home, alongside your vet's plan
- Switch to a well-fitted harness for all walking, and keep the collar for identification only. This is the highest-yield change available.
- Work on reducing barking as a behaviour, which reduces airway load as well as household stress.
- Check the face, nostrils and between the toes after any walk through long grass in summer, since awns enter at multiple sites.
- Note whether nasal discharge is from one nostril or both, and tell your vet, because that distinction changes the whole investigation.
- Count sleeping breaths weekly in any dog over eight, so an airway cough and a cardiac cough can be separated with a number rather than an impression.
- Have the MDR1 result on file, since foreign body retrieval and nasal imaging both require sedation.

What to expect, and how you know it is working
Collar-related cough usually improves noticeably within two to four weeks of switching to a harness, and often disappears entirely. Barking reduction is a project of months rather than weeks. Grass awns are resolved in a single procedure once located, though a migrated awn can take longer to find. Infectious coughs typically run one to three weeks. Serious nasal disease requires imaging and referral and follows its own course.
Success for most Sheltie owners is a dog that has stopped honking after the doorbell, walks on a harness without straining, and gets through summer without a seed head up its nose. It is not a silent dog, which this breed will never be. Where a cough has been investigated and cleared, success also includes knowing what it is not, which is worth the appointment on its own.
The barking dog's throat
Shetland Sheepdogs are among the most vocal breeds alive. That is not a training failure; it is what the breed was developed to do, and it is written into its temperament as clearly as its coat is written into its appearance.
A dog that barks hard and often is working its larynx and upper airway constantly. Add a flat collar and a dog that pulls toward whatever it is barking at, and you have repeated compression of the trachea and larynx at exactly the moment those structures are already under load.
The result, over months and years, is a dog with a chronically irritated upper airway. It produces a dry, honking cough after excitement, after a doorbell, after a walk on which the dog pulled. Owners find it alarming, and it is regularly mistaken for a heart cough or for kennel cough.
The fix is straightforward and it is the highest-yield change in this section. Move the dog onto a well-fitted harness, which distributes pull across the chest rather than the throat, and work on the barking as a behaviour problem in its own right. Many Sheltie coughs simply resolve.
What this does not fix, and what should still be investigated, is a cough that continues on a harness, a cough that is wet rather than dry, or a cough that appears at night in an older dog with a known murmur.
Problems that belong to a long nose
Long-muzzled breeds are spared the flat-faced conditions and are more exposed to a different set.
- Grass awns and foreign bodies. A dog that quarters long grass with its nose down inhales seed heads. The signature is a sudden violent bout of sneezing that starts in a field, often with discharge or blood from one nostril only. It needs removing under sedation and it will not resolve on its own.
- Fungal infection of the nasal chamber, which occurs preferentially in long-nosed breeds and typically produces persistent one-sided discharge, nosebleeds and pain or ulceration around the nostril.
- Nasal tumours, which are also more common in dolichocephalic breeds and present similarly with progressive one-sided discharge in an older dog.
- Reverse sneezing: a dramatic snorting inward spasm that alarms owners and is generally harmless, usually resolving in under a minute. Frequent episodes are worth mentioning but a single one is not an emergency.
- Kennel cough and other infectious respiratory disease, which produce a harsh hacking cough, sometimes with a retch at the end, and are common in dogs that go to classes, shows and boarding.
- The rule that ties these together: anything one-sided is a red flag. A discharge from one nostril, or a nosebleed from one side, needs proper investigation rather than a course of antibiotics.
Six months of cough, fixed by a harness
Anwen's Sheltie, Bryn, developed a dry honking cough at four. It came after the postman, after visitors, and after every walk. She was convinced it was his heart, and two separate vets found nothing on auscultation. The third vet she saw asked what he walked on. Bryn wore a flat collar, and Anwen described him as pulling hard while barking at other dogs, which she had accepted as normal for the breed. She bought a Y-front harness that afternoon and started a barking programme with a local trainer the following week. The cough reduced within a fortnight and was gone within two months. Bryn still barks. He barks a great deal, because he is a Shetland Sheepdog. But he does it without his throat being compressed at the same time, and Anwen has not heard the honk in three years.
Key takeaway: In a breed that barks constantly and pulls toward what it barks at, a flat collar is a chronic airway insult. Try a harness for a month before assuming a cough is coming from the chest.
Frequently asked questions
Are Shetland Sheepdogs brachycephalic?
No, and it is the opposite. Shelties have a long, narrow, tapering muzzle. Brachycephalic airway syndrome, stenotic nares and elongated soft palate are conditions of flat-faced breeds and have nothing to do with this one. Information written for bulldogs and pugs does not apply here.
Why does my Sheltie make a honking cough?
In a heavily barking dog on a flat collar, chronic upper airway irritation is the commonest reason. It is typically dry, comes after excitement, and improves markedly within weeks of switching to a harness. If it persists on a harness, it needs investigating rather than accepting.
What is reverse sneezing and should I worry?
A spasm in which the dog pulls air rapidly inward through the nose, making a dramatic snorting noise. It looks frightening and is usually harmless, ending within a minute. Gently stroking the throat or briefly covering the nostrils often stops it. Frequent or prolonged episodes are worth mentioning to your vet.
My dog sneezed violently in a field and now has a bloody nose on one side.
That is a grass awn until proven otherwise and it needs a same-day appointment. Seed heads migrate and do not come out on their own. Retrieval usually requires sedation, which in a Shetland Sheepdog means the MDR1 genotype should be on file before you go.
How do I tell a heart cough from an airway cough?
Count sleeping breaths. A dog whose resting breathing rate while asleep is normal and stable is very unlikely to be coughing from fluid on the lungs. A dry honking cough after excitement in a barky dog points to the airway; a soft wet cough at night in an older dog with a murmur points to the heart.
Is kennel cough dangerous for a Sheltie?
In a healthy adult it is usually self-limiting but unpleasant and highly contagious. It matters more in puppies, elderly dogs and any dog with underlying heart or airway disease. Vaccination is worth discussing if your dog attends classes, shows or boarding kennels.
What are the signs of respiratory disease in Shetlands?
The early signs are set out in the sections above, and they are the reason to book a veterinary appointment rather than wait. Respiratory Disease in Shetlands is diagnosed by a vet, not from a symptom list, and the sooner it is on record the more options remain open.
Quick answers
View more answersLiving
Should a Sheltie wear a collar or a harness?
A harness for walking. In a breed that barks and pulls, a flat collar puts repeated pressure on the throat and is a common cause of chronic cough.
Health
Is a nosebleed from one nostril serious?
Yes. One-sided nasal discharge or bleeding warrants proper investigation rather than an antibiotic course, and needs a prompt appointment.
Costs
How much does removing a grass awn cost?
Sedation and retrieval typically runs a few hundred dollars, and considerably more if the awn has migrated and needs imaging to locate.
Training
Can barking be reduced?
Substantially, though not eliminated, since this breed is bred to be vocal. A trainer can reduce frequency, which also helps the throat.
