What You Need To Know About Congestive Heart Failure in Dogs

Early indications of heart disease in senior dogs can be difficult to spot, but every symptom must be taken seriously. Congestive heart failure can be slowed down or avoided with early detection and treatment of specific cardiac conditions.

Senior dogs frequently experience cardiac disease, which can progress to heart failure. Dr. Bonnie Lefbom, a veterinary cardiologist, says cardiac disease varies between 15% and 30% in aged small dogs and 5% to 15% in large breed dogs.

Chronic degenerative valve disease is one common cause of heart failure in dogs. "Just like in older people, the heart valves can start to break down and leak, causing backflow in the heart and a heart murmur," says Dr. Lefbom. "Over time, with continued backflow through the valves, the heart enlarges. When the heart gets too big, fluid backs up in the lungs."

Cardiomyopathy, a disorder of the heart muscle, is another common cause of canine heart failure. With this condition, the valves remain healthy, but the heart's muscles become thin, reducing how efficiently the heart can pump blood. According to Dr. Lefbom, the pump malfunction leads to fluid accumulation in the lungs or the abdomen.

While congestive heart failure in dogs is incurable, it can be managed. A dog's quality of life can be improved with the medications, extending longevity. Your best bet is to talk to your veterinarian for advice and recommendations.
