Dog is breathing heavily or due to abnormalities in the respiratory system
Abnormalities in upper airway obstruction that restrict deep breathing movements, such as narrowed or blocked nasal passages or nostrils, abnormal function of the throat, nasopharynx Polyps or tumors at the site, collapsed or compressed trachea, acromegaly.
Insufficient alveolar gas exchange caused by lower respiratory tract diseases, such as pulmonary edema, pulmonary hemorrhage, pneumonia, pulmonary interstitial fibrosis, bronchiectasis, emphysema, lobar torsion, primary or Metastatic tumors, asthma. Diseases of the pleural cavity such as pleural effusion, pneumothorax, mediastinal tumor, diaphragmatic Hernia.
Or due to abnormal heart function
Poor heart function is also one of the causes of heavy breathing in dogs, such as heartworm disease, Pulmonary embolism, cardiopulmonary vascular dysplasia. Left ventricular stagnant heart failure such as mitral valve atresia regurgitation, congenital bypass of left to right heart, cardiomyopathy, atrial fibrillation. Insufficient cardiac output such as arrhythmia, subaortic or pulmonary stenosis, cardiac tamponade. Bypass from the right heart to the left heart, such as open ductus arteriosus, quadruple malformation of Fallot, dextral aortic malformation, etc.
Or due to blood diseases
Insufficient blood oxygen delivery capacity such as anemia (anemia can be caused by various reasons), degenerative hemoglobinuria Syndrome, carbon monoxide poisoning. Because the oxygen content transported in the blood is very low, the dog needs to breathe heavily to get more oxygen, and the breathing becomes heavier.
Dogs can also breathe heavily after exercising and in hot weather
In addition to physical reasons, dogs may also suffer from heavy breathing under normal circumstances Happening. Under normal circumstances, a dog who has just finished exercising will definitely breathe heavier and faster. In summer, due to the sultry environment, the dog’s breathing will become heavy in order to dissipate heat. These are normal conditions, and the dog’s breathing will soon return to normal after calming down. If the dog has this condition very early, and the condition gradually gets worse over time, it is basically caused by a disease or poor heart function, and the owner should send the dog to the hospital for treatment as soon as possible.
