Symptoms of laryngitis in dogs:

1. Coughing is the main symptom of this disease. In the early stage, because there is not much exudate, it is mostly a dry and painful short cough. As the exudate increases, the cough becomes long and moist, and the pain is relieved. Coughing worsens when exposed to cold and often occurs as spasmodic coughing, with abnormal vomiting occurring after coughing.

2. The larynx is swollen, the head and neck are stretched, and the inspiratory breathing is difficult. In severe cases, it may even cause suffocation.

3. Palpation of the larynx shows that due to swelling and increased sensitivity of the laryngeal mucosa, the sick dog is in pain, ducking, shaking its head and stretching its neck.

4. During laryngeal auscultation, dry rales can be heard when the exudate is small and thick. When the exudate is thin, loud bubbling sounds can be heard. When the larynx is severely swollen and highly narrowed, a laryngeal stenosis sound can be heard.

5. Sick dogs sometimes discharge serous, mucus or mucopurulent nasal fluid.

6. In mild laryngitis, systemic symptoms generally do not change significantly.

7. Severe laryngitis, elevated body temperature, increased pulse rate, and difficulty breathing.

8. Chronic laryngitis, long-term fever, dull cough, and hoarse cough. The larynx is slightly sensitive to palpation. Rhinitis and laryngoscopy revealed that the mucosa was hypertrophic, swollen, and granular or nodular.

Common causes of laryngitis in dogs:

1. Primary laryngitis is mainly caused by cold, chemical, thermal and mechanical stimulation. .

2. Secondary laryngitis is often caused by the spread of inflammation in adjacent organs. Laryngitis is often complicated by the onset of certain viral or bacterial infectious diseases (such as canine distemper, influenza, mycoplasmosis, canine adenovirus disease, etc.).
