Frequency

• Congestive heart failure affects 1 in 10 dogs at some point in their lives, but many owners fail to recognize the symptoms in time to get the necessary care.
  
  

Causes

• Congestive heart failure can occur in young dogs as a result of a birth defect. Heartworms, if not detected and treated quickly, can lead to the problem. As dogs age, their heart valves can deteriorate or their pericardium can become diseased.
  
  

Symptoms

• Canine congestive heart failure is associated with fluid build-up in the lungs, abdominal cavity and/or chest cavity. Common symptoms include labored breathing, coughing and listlessness. You may also notice your dog losing a lot of weight and appearing constantly fatigued.
  
  

Treatments

• With proper care, your dog can live a comfortable and reasonably normal life. Your veterinarian may suggest a change in your dog's diet or prescribe medication. Treatments include diuretics and other dietary supplements in pill form; and nitroglycerin paste or cream. Your veterinarian may use a small needle to drain excess fluid from around the lungs to relieve pressure and improve your dog's breathing.
  
  

Warning

• Congestive heart failure can be fatal if not treated quickly. Visit the vet if you notice the symptoms. The faster your dog is treated, the sooner he or she will get better.
