# [Dog Reverse Sneezing](/knowledge/veterinary-medicine/clinical-methods/dog-reverse-sneezing) And Coughing


## Key Takeaways

- Reverse sneezing, or paroxysmal respiration, is a reflex characterized by rapid, forceful nasal inhalation, producing snorting or honking sounds, typically lasting seconds to a minute and often triggered by excitement or eating.
- Coughing is a forceful exhalation from the lungs, often described as hacking or gagging, and can be indicative of various underlying conditions including infectious tracheobronchitis (kennel cough), allergies, collapsing trachea, or cardiac disease.
- Differentiating between the two involves observing the sound (inhalation vs. exhalation), posture (neck extended vs. hunched), and duration of the episode, with video recording recommended for veterinary consultation.
- While most reverse sneezing episodes are benign, persistent coughing, difficulty breathing, cyanotic gums, lethargy, fever, or appetite loss necessitate immediate veterinary evaluation for potential serious conditions.
- Home care for reverse sneezing may involve gentle throat massage or briefly covering nostrils to encourage swallowing, whereas mild coughing can be managed with harnesses, humidification, and allergen avoidance, but human over-the-counter medications are strictly contraindicated.
- Veterinary diagnostics for coughing may include blood tests (e.g., for heartworm antigen/antibody), thoracic radiography, and potentially tracheal washes or bronchoscopy, with treatment tailored to the etiology, such as antimicrobials for bacterial infections or diuretics for congestive heart failure.

If your dog has ever made a sudden, dramatic snorting or honking sound, you may have wondered whether they are coughing, sneezing, or something else entirely. These episodes can be startling, but they are often harmless. Understanding the difference between reverse sneezing and coughing will help you know when to stay calm and when to call the vet.

## Quick Q&A: Common Questions

**Question:** How can I tell if my dog is reverse sneezing versus coughing?

**Answer:** Reverse sneezing sounds like a forceful, rapid inhalation through the nose, creating a snorting or honking noise. Coughing is a forceful exhalation from the lungs, often producing a hacking or gagging sound. Reverse sneezing episodes usually last a few seconds to a minute, while coughing tends to be repetitive and may be accompanied by phlegm.

## What Is Reverse Sneezing?

Reverse sneezing, medically known as paroxysmal respiration, is a common reflex in dogs. It occurs when the soft palate and throat become irritated, causing the dog to rapidly and forcefully inhale air through the nose. The result is a series of loud snorts or honks that can sound alarming. Most dogs remain conscious and normal between episodes.

## What Causes Coughing in Dogs?

Coughing is a different mechanism. It is a protective reflex that expels irritants, mucus, or foreign material from the airway. Common causes include:

- **Kennel cough** (infectious tracheobronchitis) – a highly contagious respiratory infection.
- **Allergies** to pollen, dust, or mold.
- **Collapsing trachea** – common in small breeds like Yorkies and Pomeranians.
- **Heart disease** – especially in older dogs, where fluid builds up in the lungs.
- **Lungworms, heartworms, or fungal infections.**

Unlike reverse sneezing, coughing often occurs in fits and may be productive (bringing up fluid) or dry.

## Differentiating Between the Two

| Feature | Reverse Sneezing | Coughing |
|-----|---------|-----|
| Sound | Snorting, honking, repeated inhalation | Hacking, gagging, or moist sounds on exhalation |
| Posture | Standing still, neck extended, elbows out | Often hunched, head low, mouth open |
| Duration | Seconds to one minute | Can last minutes or occur in fits |
| Triggers | Excitement, eating, drinking, pulling on leash | Exercise, breathing in irritants, lying down |

If you are unsure, record a video to show your veterinarian.

## Should You Worry?

Most reverse sneezing episodes are harmless. However, coughing can signal a more serious problem. Seek veterinary care if your dog:

- Coughs persistently for more than 24 hours
- Has difficulty breathing, blue gums, or collapses
- Produces blood or foam when coughing
- Shows lethargy, fever, or loss of appetite
- Is a puppy, senior, or has a known heart condition

## Home Care for Reverse Sneezing

When your dog reverse sneezes, stay calm. You can try:

- Gently massaging the throat
- Briefly covering the nostrils to encourage swallowing
- Offering a small drink of water

Once the episode stops, your dog will likely return to normal. If episodes become frequent (more than once a day) or are accompanied by discharge or sneezing, consult your vet.

## Home Care for Mild Coughing

For a mild, non-worrisome cough (e.g., after pulling on leash or from mild allergies):

- Use a harness instead of a collar to reduce pressure on the trachea.
- Run a humidifier or bring your dog into a steamy bathroom for 10 minutes.
- Keep your dog away from dust, smoke, and strong fragrances.

NEVER give over-the-counter human cough medicines to your dog. Many contain ingredients like acetaminophen or xylitol that are toxic to pets.

## What to Expect at the Vet

Your veterinarian will take a history and perform a physical exam. They may recommend:

- **Blood tests** to check for infection or heartworm.
- **X-rays** of the chest and throat.
- **Tracheal wash or bronchoscopy** to collect samples.
- **Echocardiogram** if heart disease is suspected.

Treatment depends on the cause: antibiotics for bacterial infection, cough suppressants for persistent dry cough, or surgery for severe tracheal collapse.

## Prevention Tips

- Keep your dog at a healthy weight to reduce pressure on the airway.
- Avoid exposure to sick dogs and keep vaccinations current.
- Use a harness rather than a collar.
- Limit exposure to known allergens.
- Practice good dental hygiene (dental disease can trigger throat irritation).

## When to Act

Reverse sneezing is rarely an emergency. Coughing, especially when persistent or accompanied by other symptoms, requires prompt veterinary attention. By learning the difference between [dog reverse sneezing](/knowledge/veterinary-medicine/clinical-methods/dog-reverse-sneezing) and coughing, you can respond appropriately and keep your furry friend comfortable.
