This is known as a reverse sneeze. It is common in small-breed dogs, especially when they get excited or are drinking water. Owners become concerned when their pet makes these noises; some even fear that their pet cannot breath. In general, it does not cause the dog any harm and does not lead to any significant breathing problems. Reverse sneezing usually goes away within a few seconds to minutes. It may be helpful to massage the neck and try to calm the animal if it was previously excited. Some animals can have this condition for their entire lives, or it may develop as the animal ages.

Causes of reverse sneezing include allergies, viral infections, excessive soft palate tissue, and nasal mites. Some cases of reverse sneezing are idiopathic, which means there is no identifiable cause. A reverse sneeze results from irritation to the nasopharynx. This irritation causes the loud inspiratory and expiratory snorts that prompt the owner to take the dog to the veterinarian. The nasopharynx can be thought of as the part of the throat just above the soft palate. The soft palate is a soft, fleshy tissue extension off the hard palate, or roof of the mouth. If this problem continues, or appears to be severe, you should consult with your veterinarian. However, most of the time there is nothing to worry about.
