Reverse Sneezing in Dogs: Causes & How to Help

What Causes Reverse Sneezing in Dogs?

Reverse sneezing occurs when the muscles of the larynx spasm temporarily, causing a loud snorting or honking sound as the dog tries to inhale. This condition is believed to be triggered by a drop of mucus falling from the soft palate onto the vocal cords. It is commonly seen in small and brachycephalic breeds such as Shih Tzus, Corgis, and Beagles. Episodes are often set off by excitement, eating quickly, or greeting others. The dog may stand still, extend their head, and make repeated snorting noises, but they usually return to normal immediately after the episode.

How to Help Your Dog During a Reverse Sneezing Episode

When your dog experiences reverse sneezing, remain calm—this helps reduce their stress. You can gently massage the front of their neck just below the jaw to encourage swallowing, which often ends the spasm. Another effective method is to briefly cover their nostrils with your hand to force them to breathe through their mouth, which can help reset their breathing. Lightly blowing air into their face may also relieve the episode. Avoid panicking or restraining them too tightly, as this can increase anxiety.

When to Seek Veterinary Help

While reverse sneezing is usually harmless and resolves on its own, seek veterinary attention if your dog collapses during an episode or if the attacks become frequent and severe. These signs may indicate a foreign object in the airway or a more serious condition like laryngeal paralysis. Persistent or worsening symptoms, such as noisy breathing at rest, a weak or croaky bark, or fainting, require professional evaluation. In rare cases, surgical intervention may be needed to correct structural issues in the airway.

Breeds Most Prone to Reverse Sneezing

Reverse sneezing is most common in short-faced (brachycephalic) breeds, including Shih Tzus, Pugs, Boston Terriers, Bulldogs, and Pekingese. These dogs often have anatomical features like collapsed nostrils (stenotic nares) and soft palates that contribute to breathing difficulties. While not all dogs in these breeds experience reverse sneezing, many will show some degree of respiratory irregularity, including snorting, gagging, or honking sounds. The condition is often intermittent and does not typically affect the dog’s overall health.

Preventing Triggers and Managing Symptoms

To reduce the frequency of reverse sneezing episodes, avoid sudden excitement or rapid eating. Feed your dog slowly using a special bowl or toy to prevent gulping. Keep the environment free from irritants like perfumes, smoke, scented candles, and strong cleaning agents, which can trigger nasal irritation and sneezing. If your dog has a history of breathing issues, avoid exercising in hot weather, as overheating can worsen airway swelling and breathing problems.
