Reverse sneezing (also called backwards sneezing) or inspiratory paroxysmal respiration is a phenomenon observed in dogs, particularly in those with brachycephalic skulls. Its exact cause is unknown but may be due to nasal, pharyngeal, or sinus irriation (such as an allergy) or the dog's attempt to remove mucus. It is characterized by rapid and repeated forced inhalation through the nose, accompanied by snorting or gagging sounds. It is alarming to the owner and may be distressing to the dog, but is not known to be harmful to the animal. Most dogs are completely normal before and after episodes. In addition most dogs will have repeat episodes of it during their lives.

According to Dr. Holly Frisby, DVM, "During a reverse sneeze, the dog will make rapid and long inspirations, stand still, and extend his head (and neck). A loud snorting sound is produced...."

Reverse sneezing also commonly occurs while the dog is asleep, and also immediately following a long nap. [1]. Other dogs may experience it following play, exercise, or meals, but most of the time episodes are completely random. Smaller dogs seem slightly more susceptible to it; however any dog can develop it regardless of size.

Differential diagnoses include tracheal collapse [2].

A common remedy is to pinch the dog's nose and scratch its throat. Lightly blowing in its face may also help. The dog will swallow a couple of times and then stop the reverse sneezing. Additionally, calming the dog down by rubbing its sides or back also helps to end the episode more quickly. While most dogs do not require medication, antihistamines and steroids may help if the problem is serious, chronic, and allergy-related.
