Causes of heart failure in dogs:

1. Temporary overload of the dog’s heart is the most common cause of acute heart failure, such as dogs that have been idle for a long time. Sudden strenuous exercise; when treating diseases, infusion speed is too fast or too much, especially drugs that have strong irritation to the myocardium (such as calcium preparations).

2. Heart failure is often secondary to certain diseases, such as canine parvovirus, toxoplasmosis, myocarditis, various toxic diseases, chronic endocarditis, chronic nephritis, etc.

Preventive measures for dog heart failure:

1. Strengthen care: Dogs with acute heart failure should be allowed to rest quietly immediately and all training and work should be stopped. Give food that is easy to digest and absorb. Dogs that have difficulty breathing should be given oxygen immediately.

2. Enhance myocardial contractility: For dogs with acute heart failure, quick-acting and efficient cardiotonic drugs should be used for first aid.

3. Reduce cardiac load: For sick dogs with cardiac edema, appropriately limiting the amount of drinking water and salt and using appropriate diuretics will have better curative effects.
