Congestive heart failure is the result of an abnormality in the heart's structure or function. As a result the dog's heart is unable to pump normal amounts of blood to the tissues of the body. When this happens, fluid builds up in the lungs and the body cavities, which leads to congestive heart failure. Dogs of any age and breed can develop congestive heart failure.

Causes
-
A dog may experience heart failure due to many factors including birth defects, irregular electrical rhythms of the heart or degeneration of the heart valves. In addition, certain diseases may cause heart failure. These diseases include heart muscle disease, heartworm disease or diseases of the pericardium, which is the lining around the heart.
Symptoms
-
When the amount of blood that is pumped to a dog's muscles is reduced, it can case a dog to feel tired, lose weight, cough, experience shortness of breath and difficulty breathing.
Similar Diseases
-
It's important to keep in mind that similar diseases may show similar symptoms to those associated with congestive heart failure. Dogs with tracheal collapse and chronic bronchitis have symptoms of chronic coughing. Pneumonia, a lung infection or tumors of the chest can also lead to similar symptoms. Some diseases, such as heartworm, disease, can lead to congestive heart failure. According to Pet Place, "Heartworm disease, a parasitic infection of the blood vessels of the lungs, must be excluded as a possible diagnosis. This infection can also lead to heart failure as well as lung injury."
Diagnosis
-
Diagnosis may require numerous tests. Tests may include a complete medical history, blood tests, X-rays, a measure of blood pressure, an electrocardiogram (EKG) or an ultrasound examination. Specialized tests may include thyroid tests, blood cultures or a thoracocentesis, which is the process of draining fluid from around the lungs.
Treatment
-
Treatment may include drugs such as furosemide or nitroglycerine. A diet that limits sodium will help prevent fluid retention. In addition, hospitalization may be required. Home care will also be essential. It's important to follow the veterinarian's instructions and regularly give your dog its medications. Make note of any symptoms you notice, such as coughing or fatigue, and monitor the dog's appetite and breathing ability. See your veterinarian immediately if you notice difficulty in breathing. Pet Place notes, "Once diagnosed, you should prevent excessive physical activity or excitement, avoid high heat/humidity and avoid high salt (sodium) foods or treats."
