Dog rhinitis is mainly caused by cold weather or a sudden drop in temperature, which causes the nasal mucosa to be irritated. Secondly, it may also be caused by inhalation of overly irritating gases or inflammation of the nasal mucosa caused by insects. In addition, it may also be secondary to infectious diseases such as canine distemper, influenza, and bronchitis. It is recommended that you take your dog to a pet hospital for imaging examinations such as nasal endoscopy and CT to confirm the specific cause, and then treat it according to the cause.

1. Caused by weather

When the weather is cold or the temperature drops sharply, the dog's nasal mucosa is irritated, causing congestion and exudation, and the bacteria remaining in the nasal cavity develop and multiply, causing mucosal inflammation. Winter is generally the season with the highest incidence of rhinitis.

2. Caused by debris

If the dog inhales ammonia, smoke, dust, pollen, insects, or some disinfectants, air fresheners and other pungent smelling things, it will directly irritate the dog's nasal mucosa, causing inflammation of the nasal mucosa.

3. Cause of disease

Rhinitis in dogs may also be secondary to the spread of certain infectious diseases or inflammation of nearby organs. For example, infectious diseases such as canine distemper, influenza, bronchitis, nasal mites, pharyngitis, and sinusitis.
