Heart failure is most common in dogs with heart disease. It is the inability of the heart to provide sufficient blood circulation for the metabolic needs of the body.

Blood supply to the organs worsens, which leads to pathological changes in the myocardium. The cause of heart failure may be a variety of heart disease:

  1. Congenital malformations,
  2. Cardiomyopathy,
  3. Cardiosclerosis,

  • Pulmonary wheezing.

Fainting, liver enlargement, swelling are also possibleLimbs and a dewlap. The dog is quickly tired, very sluggish. In her lungs can be heard wheezing. The heart often grows in volume. With left ventricular failure, pulmonary edema may develop.

Chronic heart failure (CHF) is characterized by a relatively slow and relatively stable development, often against the background of previously transmitted diseases. Sometimes the only symptom of such heart disease in a dog can be a chronic cough.

In acute heart failure, there is a rapid increase in symptoms, literally from a few minutes to several hours. The most characteristic features are:

  • dyspnea,
  • Wheezing,
  • cough,
  • Pallor of the mucous membranes,
  • Increased heart rate

When there is edema, the animal is given a diuretic:

  1. Furosemide,
  2. Will regulate,
  3. Spironolactone.
