What can a runny nose and sneezing in a dog be caused by?
Respiratory tract infection
An infection of the respiratory tract can be caused by viruses and bacteria. The symptoms are similar to respiratory infections in people with sneezing, a runny nose, cough and possibly a fever. Most cases are self-limiting. However, in more severe cases, a dog may develop pneumonia. An example of an infection that can lead to cold symptoms is kennel cough.

As a result of a respiratory infection, your dog may start coughing. However, there are many reasons for coughing, other than infection and inflammation. If a dog has respiratory symptoms, it is a good idea to have the dog assessed by a vet. For mild cases, it is best to get your dog assessment by a vet at home. Infections such as kennel cough are highly infectious and therefore can easily spread to other dogs. If your dog does not show signs of improvement, then an examination at the clinic, and in some cases treatment, may be needed.
Changes in the nasal cavity
A runny nose and sneezing can be signs of changes inside the nasal cavity. Dogs sometimes get foreign body, such as a grass seed, stuck there, which causes irritation. Small growths, such as a polyp or a tumour, can also develop in the nose. The symptoms are usually sneezing and a runny nose. If the problem seems to only affect one nostril, you will be able to feel a difference in airflow down each nostril. Nasal discharge can vary from clear to yellow to grey to blood. Fever and a cough are uncommon in these cases. To examine the nasal cavity, you can either examine the nose with a camera (fibre endoscope) or a CT or MRI scan.
Nasal mites are small mites that can live in the nasal passages and sinuses. They are found world wide and affect dogs of all breeds, ages and sex. The dog may experience symptoms such as sneezing, nose bleeds, “reverse sneezing”, a runny nose and facial itching. There is no evidence to suggest that these mites are a risk to humans.

In advanced dental problems, such as tooth decay and infections, fistula tracts can form between the oral and nasal cavities. This can lead to symptoms associated with the nose such as sneezing and a runny nose. If the dog has symptoms from the nose, always carefully check your dog's mouth, and if in doubt seek vet advice.
Certain allergic conditions can cause a runny nose, sneezing and watery eyes. In many cases, this is usually seasonal, such as allergy to grass or tree pollen. You may also notice your dog licking and chewing their paws, or brown saliva staining on the feet, between their toes.
