Clinical symptoms: The dog’s early manifestations are long-term cough, poor expectoration and varying degrees of dyspnea, especially after walking the dog or when the weather changes suddenly. Cardiopulmonary function in the early stage of the disease can still be compensated by increasing heartbeat and breathing. Dogs may have no obvious symptoms.
As symptoms progress, the dog coughs repeatedly for a long time, with a sputum sound in the throat, and the coughed up sputum is thick and yellow. You can hear the dog’s shortness of breath and feel that the dog is breathing hard when the dog is moving slightly, such as when the dog is climbing stairs or when the dog is running. After the run, the dog’s symptoms such as weakness and tiredness can be improved after rest.

In order to cooperate with the treatment, routine blood tests and X-ray chest angiography are generally required.
Blood routine examination: use an automatic hemocytometer to check the blood routine. If the food intake decreases for a long time, the red blood cell count and hemoglobin value may drop; The proportion of cells will increase, and other indicators are generally normal or have no obvious changes.
X-ray chest angiography: X-ray films show that the area of the heart is enlarged and the heart is spherical.
Clinically, a comprehensive treatment plan of cardiotonic, diuretic and bronchial expansion is required for this disease.
Increase cardiac output and improve cardiac function: Oral therapy with anti-heart failure drugs such as pimobendan can be used. Taking these drugs in the early stage of the disease can effectively prevent the occurrence of critical symptoms, but dogs may Such drugs produce a strong dependence, and there will be more serious acute heart failure after the drug is discontinued. Oral Danshen dripping pills or intravenous injection of astragalus injection can also be used. These drugs benefit qi and nourish qi, strengthen the body and eliminate pathogenic factors, nourish the heart and dredge the pulse, invigorate the spleen and remove dampness. Not all very helpful.
Remove excess water in the body and reduce pulmonary edema: Intravenous injection of furosemide can be used to remove excess fluid accumulated in the lungs and reduce pulmonary edema. During the development of this disease, dogs often drink a disproportionate amount of water and excretion, which leads to an increase in body fluid volume, and a large amount of water accumulates in the lungs, causing pulmonary edema and affecting gas exchange. Therefore, if the dog’s urinary system is functional, it can be used repeatedly 2 to 3 times according to the physical condition of the case, but it is necessary to pay attention to supplement potassium during the process of diuresis to prevent kidney failure.
Bronchi dilation and increased air intake: Aminophylline can be used intravenously to rapidly dilate the bronchial tubes, make the airway unobstructed, and increase the oxygen supply. Especially when the dog shows severe breathing difficulties, raised head, sluggish eyes, round eyes, severe shortness of breath, and sputum flow from the nose and mouth, it can be doubled for intravenous injection.

Therefore, after the pet dog becomes an adult, it is necessary to control its weight, raise it reasonably, and feed it once a day when it does not perform high-intensity exercise every day.
Prevention and treatment of dog respiratory infections: Respiratory diseases in pet dogs can be caused by microorganisms such as viruses, mycoplasma, chlamydia and bacteria. The body resistance of elderly dogs is reduced, and the integrity of the respiratory mucosa epithelium is easily invaded by pathogenic microorganisms. Therefore, elderly dogs over 10 years old should pay attention to keeping warm and cold to prevent colds; at the same time, regular injection of dog vaccines can greatly reduce the incidence of respiratory tract infections in dogs. probability.
