Causes of Dogs Sneezing and Runny Nose: What You Need t

Common causes of a dog's discharge from the nose, which can appear as either a watery or puslike substance, include the following:

1. Paranasal Sinusitis: This condition presents with puslike discharge. The affected area may swell and become tender, and an Xray will show reduced permeability in the affected region.

2. Acute Rhinitis: The discharge is typically watery, mucoid, or purulent.

3. Chronic Rhinitis: The discharge is usually puslike, with thickened nasal mucosa, often developing from an acute rhinitis.

4. Cold: This often occurs after exposure to cold, resulting in clear, watery nasal discharge, often accompanied by a rise in body temperature.

5. Pneumonia: The discharge is mucoid or purulent, and symptoms may include difficulty breathing and lung rales.

6. Canine Distemper: Secondary infections can lead to mucoid or purulent discharge, along with eye discharge and other symptoms associated with canine distemper.

7. Pulmonary Edema: The discharge takes on a frothy consistency.
