Dog asthma or respiratory system reasons

Obstructive abnormalities of the upper respiratory tract limit deep breathing, such as nasal or nostril stenosis or obstruction, and functional abnormalities of the throat. , polyps or tumors in the nasopharynx, collapse or compression of the trachea, and acromegaly. Lower respiratory tract diseases cause poor alveolar gas exchange function, such as pulmonary edema, pulmonary hemorrhage, pneumonia, interstitial pulmonary fibrosis, bronchiectasis, emphysema, lobar torsion, primary or metastatic lung tumors, and asthma. Diseases of the pleural cavity such as pleural effusion, pneumothorax, mediastinal tumors, and diaphragmatic hernia.

Asthma or Abnormal heart function in dogs

Cardiovascular dysfunction, such as filariasis, pulmonary embolism and cardiopulmonary disease Abnormal development of blood vessels. Left ventricular congestive heart failure, such as cap atresia and regurgitation, congenital left-to-right accessory pathway, cardiomyopathy, atrial fibrillation. Inadequate cardiac output, such as cardiac arrhythmias, subcortical or pulmonary stenosis, and cardiac tamponade. Bypass from right heart to left heart, such as open ductus arteriosus, quadruple malformation of Fallot, right aortic malformation, etc.

Dogs have asthma orblood diseases

Insufficient blood oxygen transport capacity such as anemia (there are many reasons that can cause anemia in animals), Metahemoglobinuria, carbon monoxide poisoning. Metabolic acidosis caused by excessive blood carbonate, such as kidney disease, diabetes, shock, diarrhea, poisoning and other factors.

Asthma or nervous system abnormalities in dogs

Head injuries or brain tumors may affect the respiratory center. Myasthenia gravis, tetanus, polyneura and neuritis cause respiratory muscle dysfunction. Diaphragmatic paralysis occurs in diabetic psychosis. Epilepsy causes excitement of the respiratory center, accumulation of lactic acid, and increase in body temperature, which also causes shortness of breath.

Other causes of dog asthma

Increased abdominal pressure and diaphragm compression caused by obesity, ascites, organ enlargement, pregnancy, etc., leading to shortness of breath and fever , heat stroke, thyroid poisoning, nervousness and excitement.
