2. Teething: During the teething process, puppies may experience increased salivation and nasal discharge. The milky white liquid could be a combination of saliva and mucus that is produced as the puppy's teeth erupt.
3. Allergies: If your puppy has allergies, they may experience nasal discharge as a reaction to allergens such as pollen, dust, or food. The discharge may be accompanied by other symptoms such as sneezing, itchy eyes, and skin irritation.
4. Respiratory infection: In some cases, a milky white discharge from the nose can be a sign of a respiratory infection, such as a viral or bacterial infection. Other symptoms of a respiratory infection may include coughing, sneezing, lethargy, and decreased appetite.
5. Foreign object: Occasionally, a milky white discharge from the nose can be caused by a foreign object lodged in the puppy's nasal passage. This can occur if the puppy inhales something like a piece of grass or a small toy.
If you are concerned about the milky white discharge from your puppy's nose, it is always a good idea to consult with a veterinarian to determine the cause and receive appropriate treatment if necessary.
