Symptoms of Bronchitis in Dogs
📝 Summary
Canine bronchopneumonia refers to inflammation of a single lung lobule or part of a lobule, also called lobar pneumonia in dogs. Early bronchopneumonia is not difficult to treat and can usually be controlled and cured with daily care and proper medication, with a cure rate above 95%. The disease is mostly caused by cold stimulation, mechanical and chemical factors, infectious diseases, and parasitic infections, leading to acute, non-specific inflammation of the trachea, bronchial mucosa, and surrounding tissue. Its clinical features are cough, wheezing, and crackles on abdominal auscultation. It often recurs acutely in cold seasons.
1 Overview
I. Symptoms of Bronchitis in Dogs
Remittent fever, increased respiratory rate, cough, and localized pulmonary pneumonia foci are the main clinical symptoms. Canine bronchopneumonia is caused by colds and stimulated by infectious diseases, parasitic diseases, and physical and chemical factors, leading to inflammation of the bronchi and bronchioles of the lung lobules. The alveoli are often filled with catarrhal exudate composed of epithelial cells, plasma, and white blood cells, hence it is also called catarrhal pneumonia. Percussion shows scattered focal dullness, and auscultation reveals crackles. Puppies and senior dogs have higher incidence, peaking in autumn, winter, and early spring.
II. Treatment of Bronchitis in Dogs
Use ampicillin at 40 mg/kg body weight, intravenously once daily. For acute cases, give twice daily at 0.3 mg/kg, which may be combined with dexamethasone. For cough relief, expectoration, and spasmolysis, use chloramine at 0.2 g/kg body weight, orally twice daily. For chronic bronchitis, potassium iodide or sodium iodide at 20 mg/kg can be given 1-2 times daily, together with antibiotic therapy.
