Full Answer

Many of the early warning signs of congestive heart failure can be caused by other ailments. Continued problems become more indicative of the disease. A backup of fluid in the lungs frequently causes coughing. When the fluid accumulates rapidly in the small airways, the dog may cough up a red fluid. This is indicative of failure of the left ventricle. When the fluid builds up in the abdomen, legs and chest cavity, failure of the right ventricle has occurred.

Some forms of heart disease are curable if treated before the heart is damaged. Heartworms, bacterial endocarditis and congenital heart disease are all treatable if identified early. A low-salt diet, restricted exercise and medications to improve heart function are all suggested treatments for congestive heart failure. Congestive heart failure is diagnosed using chest X-rays, blood and urine tests, an electrocardiogram or an ultrasound examination.
