The causes of emphysema in dogs:

1. Primary emphysema occurs when dogs undergo strenuous exercise, rapid running, and long-term struggle due to Caused by strong breathing. Especially in older dogs, the elasticity of the alveolar walls decreases and emphysema is prone to occur.

2. Secondary emphysema often occurs due to persistent coughing in chronic bronchitis, diffuse bronchitis, or due to obstruction of bronchial gas passage when bronchial stenosis and obstruction.

3. Interstitial emphysema is caused by severe coughing or foreign matter falling into the lungs, which causes the air pressure in the alveoli to increase sharply, causing the alveolar walls to rupture.

Treatment methods for emphysema in dogs:

1. Strengthen care: First, let the sick dog rest absolutely and place it in a clean, dust-free, well-ventilated house. Within, provide nutritious food.

2. Improve ventilation and ventilation function: bronchodilators, such as theophylline and adrenergic drugs, can be taken orally or atomized. Adrenocortical steroids should be used with caution. Respiratory enhancement drug forminoben hydrochloride 50 to 80 mg, taken orally, 3 times a day. It can increase the partial pressure of oxygen in the blood of sick dogs and reduce the partial pressure of carbon dioxide. Avoid using sleeping pills, sedatives, etc.

3. Control heart failure: When edema occurs, diuretics, such as hydrochlorothiazide 10-20 mg orally, 2 times a day, or furosemide 10 mg 2 times a day can be used. When taking the medicine, you need to supplement potassium O.1~1g every day, orally, 4 times a day. If you use diuretics such as Cortisol, Triamterene, etc., you do not need to supplement potassium.

4. Oxygen therapy: low-concentration oxygen inhalation multiple times a day. Can relieve breathing difficulties and control heart failure in dogs.

5. Surgical therapy: Resection of large localized emphysema bullae can inflate the compressed normal lung tissue and enhance the elastic return of the lungs.
