The Primary Causes of Canine Sneezing

Canine sneezing is common. Dogs often sneeze when they have just woken up, or if they are laying on their backs. However, there are many causes and reasons why dogs sneeze, so coughing and sneezing should not be taken lightly. Sneezing could be a sign of disease or a respiratory disorder, which can be serious. Consult your veterinarian if your dog is displaying abnormal sneezing along with coughing, head shaking or pawing at the head.

Some of the main causes of canine sneezing

Dog Allergies

You may have noticed your dog sneezing more when pollen, weeds, dust or mold are in the air. Some dogs are allergic to cigarette smoke, so it's best not to smoke near them. Some cleaning products and laundry products may cause your dog to sneeze as well. Antihistamines usually help relieve the symptoms of allergies.


There are various types of infections that will cause sneezing, including fungus, virus and bacterial. When a dog is sneezing due to an infection, you will often observe discharge coming from the nose. The infection is serious if you see blood or puss coming from your dog's nose.

A sinus infection will cause sneezing as well as watery eyes and coughing.

Canine influenza is a new virus which was reported in 2004. It's a mutated strain of equine influenza. This virus can cause serious respiratory illness in dogs. It's not known to have infected humans.

Some of the first signs of the distemper virus include sneezing. The sneezing will be accompanied by coughing and thick mucus coming from the eyes and nose.

Most dogs with the coronavirus have symptoms of coughing, sneezing and nasal discharge.

Abscesses and Tumors

Some dogs may sneeze when they have a tooth abscess or an abscess in the gum line. Your dog's upper teeth have roots in the vicinity of its nasal passages. An infection can spread to the sinuses. Sneezing from a tooth infection is usually accompanied with drainage from the nostrils.

Intranasal tumors are a more serious cause of sneezing. Bloody discharge will also be produced. Sneezing and discharge will occur more often as the tumor progresses.

Foreign Objects

Foreign objects can become lodged in one or both nostrils and cause sneezing. Discharge is usually produced as well. Usually, when something is lodged in the dog's nose, he will shake his head or paw at his nose, as well as sneeze excessively. Some dogs will be able to dislodge the object by sneezing. Others, however, will have to have them removed by a veterinarian.
