Dogs Snorting: Common Causes, Normal vs Abnormal Signs
Snorting is a sound many dogs make from time to time, and while it is often harmless, it can sometimes point to a nasal or respiratory issue that deserves attention.

Quick Answer
Dogs snort for many reasons, including clearing the nasal passages, reverse sneezing, breed-related airway structure, allergies, or inhaled foreign objects. Snorting that is occasional and occurs in otherwise healthy dogs is often normal. However, snorting that is new, constant, or accompanied by discharge, labored breathing, or distress may indicate a problem that requires veterinary evaluation.

Normal vs. Abnormal Snorting
Not all snorting in dogs is a cause for concern. Understanding the difference between typical and atypical snorting can help you decide whether a veterinary visit is appropriate.
Normal Snorting
Snorting may be considered normal in the following situations:
- Occasional snorts after sniffing the ground, especially in dusty or grassy environments
- Brief snorting during excitement or play
- Snorting that resolves quickly and does not recur frequently
- Breeds with flat faces (brachycephalic breeds) that regularly produce audible breathing sounds
Abnormal Snorting
Snorting is more likely to be a concern if you notice:
- Snorting that is new or has changed in character
- Persistent or constant snorting that does not resolve
- Snorting accompanied by nasal discharge, blood, or swelling
- Increased effort or visible difficulty with each breath
- Coughing, gagging, or choking sounds alongside snorting
- Lethargy, reduced appetite, or other behavioral changes
If any of these signs are present, a veterinary consultation is advisable.
Common Causes of Snorting in Dogs
Reverse Sneezing
Reverse sneezing is a reflex where a dog rapidly pulls air in through the nose, producing a snorting or honking sound. It is one of the most frequently reported causes of snorting in dogs. Episodes are usually brief and self-limiting. They can be triggered by irritants, excitement, or sometimes occur without an obvious trigger.
Brachycephalic Airway Structure
Dogs with shortened muzzles, such as Bulldogs, Pugs, Boxers, and Boston Terriers, have anatomically narrower nasal passages and elongated soft palates. This structure can lead to audible snorting and snoring as part of their normal breathing pattern. While some noise is expected in these breeds, any worsening or new breathing changes should be evaluated.
Allergies and Nasal Irritation
Environmental allergens like pollen, mold, dust mites, and household chemicals can irritate the nasal lining and cause snorting. Allergic dogs may also show signs such as clear nasal discharge, itchy skin, red eyes, or ear infections.
Foreign Objects
Grass awns, seeds, or small debris inhaled during outdoor exploration can become lodged in the nasal passages. This typically causes sudden, forceful snorting or sneezing, sometimes from only one nostril. The dog may also paw at the nose or rub the face.
Infections
Viral or bacterial upper respiratory infections may cause snorting, congestion, and nasal discharge. In some cases, dental disease affecting the roots of the upper teeth can lead to nasal inflammation and snorting due to the close proximity of the tooth roots to the nasal cavity.
What to Observe
Monitoring a few details can be helpful when deciding whether veterinary attention is needed:
- Frequency: How often does the snorting occur?
- Duration: How long does each episode last?
- Triggers: Does the snorting happen after activity, during rest, or in specific locations?
- Accompanying signs: Is there discharge, pawing at the nose, coughing, or breathing difficulty?
- One or both nostrils: One-sided signs can sometimes point to a foreign body or local issue.
Recording a short video of the snorting can also be useful to share with your veterinarian during a consultation.
When to Contact a Veterinarian
Seek veterinary care if you notice:
- Snorting that is persistent or worsening
- Any nasal discharge, particularly if colored or bloody
- Visible difficulty breathing, open-mouth breathing, or extended neck posture
- Swelling, deformity, or pain around the nose or face
- Blue or pale gums
- Coughing, wheezing, or exercise intolerance alongside snorting
Signs such as difficulty breathing or discolored gums may require urgent veterinary attention.
Frequently Asked Questions
Should I be worried if my dog snores and snorts?
Mild snoring and snorting are common in many dogs, especially brachycephalic breeds. If the sounds have been present for a long time and the dog is otherwise healthy and active, they may be within normal limits. Sudden changes, increased effort, or new accompanying signs should be discussed with a veterinarian.
Can a dog snort because of something stuck in the nose?
Yes. A foreign body in the nasal passage is a common cause of sudden, persistent snorting. The dog may also sneeze, paw at the nose, or have discharge from one nostril. Veterinary removal is typically needed to resolve the issue safely.
Is snorting in puppies different from snorting in adult dogs?
Puppies may snort due to playful exploration, minor nasal irritation, or developing immune responses to new environments. However, persistent or severe snorting in a puppy, especially if accompanied by lethargy or poor feeding, should be evaluated by a veterinarian to rule out congenital airway abnormalities or infection.
