It sounds like your dog may have congestive heart failure in which the heart does not work efficiently and this allows fluid to build up in the lungs that can cause coughing. I suggest that you watch our educational video on Heart Disease in Dogs to learn more about your dog's health condition. Next, purchase our Heart Support Package to support your dog's cardiovascular health and overall vitality. If your budget allows also consider the Biopreparation F3 (use the F2 formula if your dog has been diagnosed with high blood pressure) to support your dog's cellular energy. See if this relieves your dog's coughing. If not, he may also need a diuretic prescribed by your veterinarian.
