what causes a backward sneeze in dogs
During a reverse sneeze, the dog will make rapid and long inspirations, stand still, and extend his head. A loud snorting sound is produced, which may make you think the dog has something caught in his nose. The most common cause of a reverse sneeze is irritation of the soft palate, which results in a spasm. This spasm narrows the airway and makes it temporarily more difficult for the dog to take in air.
