Congestive heart failure can cause coughing in dogs when the heart's ability to pump blood throughout the body becomes weak and fluid builds up in the lungs. However, a heart murmur is generally not nearly that serious. Instead, a more common condition in small dogs like a Chipoo is tracheal collapse in which the cartilage supporting the windpipe becomes weak and can constrict causing coughing and difficulty breathing. This would become more obvious in cold weather or during exercise like a daily walk. To confirm this you can get a diagnosis from your veterinarian. I think you are offering the correct support of her heart and you can certainly add in the Heart Glandular. I think 100 mg of COQ10 is too much for such a small dog and instead we like Doctor’s Best Ubiquinol (buy online) - purchase the 50 mg size and use a pin to puncture a whole for smaller pets and estimate dosage as best you can. Provide 25 - 30 mg per 25 lbs daily - this would only be a couple of drops for your size dog. Now to address the collapsed trachea, I suggest the Bovine Cartilage that provides type II collagen that supports the structural integrity of the trachea. If your budget allows you can also add in our Elk Velvet Antler that provides growth factors and other nutrients to promote the health of your dog's trachea.
