Reverse Sneezing in Dogs: Causes and Treatment
What Is Reverse Sneezing in Dogs?
Reverse sneezing, also known as backwards sneezing, inspiratory paroxysmal respiration, mechanosensitive aspiration reflex, or the pharyngeal gag reflex, is something dog owners witness fairly often. Those of us who are not familiar with the sound of a reverse sneeze may find it to be alarming, and some owners may think that their dog is choking or in some form of respiratory distress. Luckily, most sneezing events are short-lived and owners learn to accept them as odd and innocuous. You may still be wondering what triggers this form of sneezing in dogs and when it is something to worry about.
What Does a Dog Reverse Sneeze Look and Sound Like?
The noise can be quite strong and startling initially. At the veterinary hospital that I used to work at, we occasionally had worried clients bring their dogs in after witnessing this respiratory event. After some reassurance and owner education, these clients learned to accept the sneezing as benign.
A reverse sneeze consists of loud snorting as the air is forced through the nose. Unlike a normal sneeze where the air is pushed out of the nose, the opposite happens, and the air is pulled in through the nose. The dog's head and neck may be extended as it takes in rapid and long inspirations. Sometimes, dogs will stand still with their elbows tensed and spread apart. When coupled with the appearance of bulging or strained eyes, this characteristic stance may be visually worrisome for dog owners. Several videos are provided to demonstrate this respiratory event which is simply best understood by actually witnessing it.

What Causes Reverse Sneezing in Dogs?
While the exact cause of reverse sneezing remains unknown, it's believed to stem from some sort of irritation occurring in the nose, throat, or sinuses—the dog may be trying to clear its airway or remove mucus. When a dog reverse sneezes, a physiological spasm of the throat and soft palate occurs. Episodes may be triggered by excitement, a tight collar, exposure to allergens, and abrupt changes in environmental temperatures in some dogs. Reverse sneezing shouldn't be confused with the coughing seen in dogs with a collapsed trachea, which is considered a high-risk condition.
Reverse sneezing happens more often in small dogs. It's believed that a smaller throat and windpipe may be the predisposing factor, however, medium and large dogs are not immune to this condition. Brachycephalic dog breeds (those with shortened muzzles) are also more likely to reverse sneeze. The brachycephalic breed anatomy causes their elongated soft palates to be sucked into the throat on occasion, thus triggering a respiratory event.

How to Stop Reverse Sneezing in Dogs
Fortunately, episodes are generally short-lived. Most dogs don't appear to be bothered by them and act bright and alert after they subside. Reverse sneezing is merely annoying rather than dangerous, especially if the event happens several times in a row. There are a few methods you can use to try to stop an episode:
- Closing the nostrils and massaging the throat: Dr. Karen Becker suggests briefly closing the dog's nostrils and massaging the throat. This encourages the dog to swallow which will reverse the reverse sneezing chain.
- Blowing into the nose and offering water: Dr. Mark Hiebert alternatively suggests blowing into the dog's nose or offering a drink of water, which also elicits the dog to swallow. This technique requires caution as many dogs dislike it when humans blow air into the face, and some can even defensively bite!
- Leaving the dog alone: Most of the time, it's best to just let the dog be. However, always consult with a veterinarian for a proper diagnosis of your dog's symptoms before "ignoring" a respiratory event.
When to Seek Veterinary Advice for Reverse Sneezing
If the condition suddenly becomes chronic and increases in frequency, it is best to seek the advice of a veterinarian. Reverse sneezing may be triggered by a foreign object stuck in the airway. If you live in an area where foxtails grow, one might be stuck in your dog's respiratory tract. Respiratory events may even be caused by mites or nasal tumors. It's also important to differentiate reverse sneezing from other conditions such as a collapsed trachea or kennel cough. A recording of your dog's episodes may be of tremendous help for your veterinarian's differential diagnosis.
