Dog Reverse Sneezing A Lot And Coughing

Watching your dog suddenly make a snorting, gasping sound can be alarming. When that sound is combined with a cough, it is easy to worry about a serious health problem. However, reverse sneezing and coughing are two distinct reflexes that can occur together or separately. This guide explains what each means, why your dog might be doing both, and how to respond.

Reverse sneezing (also called paroxysmal respiration) is a rapid, forceful inhalation through the nose. It sounds like a honking or snorting gasp, often with the dog standing still with elbows out and neck extended. Coughing, on the other hand, is an expulsive exhalation meant to clear the airways. If your dog is reverse sneezing a lot and also coughing, it could indicate irritation or inflammation in the upper respiratory tract.

Quick Q&A: Common Questions

Question: Why is my dog reverse sneezing a lot and also coughing?

Answer: The combination often points to post-nasal drip, allergies, or infections like kennel cough. Reverse sneezing clears nasal irritation, while coughing protects the lower airways. When both appear frequently, the underlying cause is likely inflammation affecting the nose, throat, and trachea. Less commonly, it can signal a collapsing trachea or a foreign body.

What Is Reverse Sneezing? A Quick Refresher

Reverse sneezing is a normal reflex in dogs, especially in brachycephalic (flat-faced) breeds like Bulldogs, Pugs, and Shih Tzus. The dog rapidly pulls air in through the nose, making a snorting noise. It usually lasts a few seconds to a minute and resolves on its own. Episodes can be triggered by excitement, eating, drinking, or sudden temperature changes.

Coughing, by contrast, is a forceful expulsion of air from the lungs through the mouth. It can be dry (honking) or productive (wet). When you hear both snapping and coughing, think of the respiratory tract as a continuous tube: irritation at one end can trigger reflexes at the other.

Common Causes of Frequent Reverse Sneezing with Coughing

Allergies and Irritants

Inhaled allergens (pollen, dust mites, mold) cause nasal inflammation and post-nasal drip. The drip triggers reverse sneezing to clear the nose, and the irritation in the throat leads to coughing. Household irritants like cigarette smoke, perfume, or cleaning products can produce the same pattern.

Respiratory Infections

Kennel cough (Bordetella bronchiseptica) is a classic cause of a honking cough. Many dogs also develop a post-nasal drip, which brings on reverse sneezing. Other viral or bacterial infections such as canine influenza or distemper may present similarly.

Collapsing Trachea

Small breed dogs (Yorkshire Terriers, Pomeranians, Chihuahuas) are predisposed to a weakened trachea that collapses during breathing. This produces a classic goose-honk cough. When the trachea collapses during inspiration, it can also trigger a reverse sneeze reflex.

Foreign Bodies

Grass awns, foxtails, or small seeds can lodge in the nasal passages or pharynx. The body attempts to expel them through reverse sneezing. If the object moves to the larynx or trachea, coughing begins. This is more common in outdoor or hunting dogs.

Dental Disease

Advanced dental infections, especially in the upper back teeth, can erode into the nasal cavity. The resulting inflammation and discharge trigger both sneezing and reverse sneezing, and sometimes coughing from post-nasal drip.

Other Less Common Causes

Nasal tumors (more common in older, long-nosed breeds), elongated soft palate (brachycephalic syndrome), or sinusitis. These often produce additional signs like nasal discharge (sometimes bloody), noisy breathing, or exercise intolerance.

Home Care and Management

For mild, isolated episodes, you do not need to do anything. The episode will end on its own. If attacks are frequent or paired with coughing, you can:

  • Stay calm. Stroking your dog’s throat gently can sometimes help stop a reverse sneeze reflex.
  • Remove triggers. Use an air purifier, avoid smoke and strong scents, and wash bedding to remove allergens.
  • Humidify the air. A cool-mist humidifier or taking your dog into a steamy bathroom can soothe irritated airways.
  • Change drinking habits. Elevate food and water bowls to reduce neck flexion, which can trigger reverse sneezing.
  • Monitor for patterns. Keep a diary of episodes: time of day, environment, activity. This helps your vet identify the cause.

Do not give over-the-counter cough or cold medications intended for humans. Many are toxic to dogs. Also, do not attempt to clear a suspected foreign body yourself you could push it deeper.

When to See a Veterinarian

Schedule a vet visit if:

  • Reverse sneezing and coughing occur many times per day or last longer than a minute.
  • Your dog seems distressed, has trouble breathing, or collapses after an episode.
  • You notice nasal discharge (especially green, yellow, or bloody), fever, lethargy, or loss of appetite.
  • The cough is productive (wet) or sounds like a goose honk.
  • Your dog is a brachycephalic breed and also has noisy breathing at rest.
  • The problem started after a known exposure (boarding, dog park, ingestion of grass).

What to Expect at the Vet

Your veterinarian will start with a physical exam, carefully listening to the trachea and lungs. They may palpate the trachea to see if it triggers coughing. Common diagnostics include:

  • X-rays (radiographs) of the neck and chest to check for tracheal collapse, pneumonia, or fluid.
  • Blood tests to identify infection or inflammation.
  • Fluoroscopy (real-time X-ray video) for dynamic tracheal collapse.
  • Rhinoscopy (a tiny camera in the nose) if a foreign body or tumor is suspected.
  • Culture or PCR of a nasal or throat swab if infection is a concern.

Treatment depends on the cause. Allergies may be managed with antihistamines or a change in diet. Bacterial infections may require antibiotics. Collapsing trachea can be controlled with weight management, cough suppressants, and sometimes surgery or a stent. A foreign body will be removed under sedation or anesthesia.

Preventing Future Episodes

  • Keep vaccinations current (especially Bordetella and distemper).
  • Avoid exposure to sick dogs. Use caution at boarding facilities, dog parks, or grooming salons.
  • Maintain a healthy weight. Obesity worsens tracheal collapse and brachycephalic syndrome.
  • Use a harness instead of a collar to reduce pressure on the neck and trachea.
  • Limit outdoor time during high pollen seasons, or wipe your dog’s face and paws after walks.
  • Provide a low-stress environment. Stress can trigger reverse sneezing in predisposed dogs.

The Bottom Line

Frequent reverse sneezing paired with coughing is usually a sign of an irritated upper airway. In many cases the cause is benign and manageable at home. However, if episodes are intense, persistent, or accompanied by other symptoms, a veterinary checkup is essential. With proper diagnosis and care, your dog can return to comfortable, quiet breathing.
