My dog has an enlarged heart. What are her chances for a normal life?
If your dog is diagnosed with an enlarged heart on chest radiographs (xrays), the next step would be to see a cardiologist for an echocardiogram. Some breeds tend to have larger-appearing hearts normally. However, if your dog also has physical exam abnormalities, such as a heart murmur or arrhythmia, or symptoms, such as shortness of breath, increased panting, coughing, or exercise intolerance, it is very important to have these abnormalities looked at. Once a diagnosis is established, then prognosis can be discussed.
