I am sorry Harry does not feel well. It looks like according to the x-ray report he was diagnosed with possible dilated cardiomyopathy. This is where the left side of the heart is enlarged and not beating properly. The best option is to take Harry to a cardiologist for pets. They can do an ultrasound of the heart and determine what medications Harry needs. Most of the time these patients need medications for life. Unfortunately this is a fatal disease and needs medication for the heart to function properly. Hopefully Harry will feel better with medicines soon
