Hello, there are multiple causes for a cough like the one you are describing. One potential cause may include heartworm disease, however, this can be checked with a snap test. If it returns positive for heartworm, then there are medications you can try at home to treat this disease. Other causes may include heart disease and lung disease. Some primary lung diseases such as bronchitis and pneumonia can cause this. To fully explore this causes for your dog's cough, he may need x-rays, a cardiology consultation, and a heart worm test. The other cause in smaller dogs include a collapsing trachea. Ideally your coughing dog should not live an fast or active lifestyle to prevent exacerbation of her cough and from her going into respiratory distress. Please see your veterinarian soon if your dog continues to cough. Hope this helps and best of luck.

    Poor pup! Coughing can have a wide variety of underlying causes, from pneumonia, tracheal conditions, heart disease, heartworm disease, etc. Without an exam and chest x-rays, it is difficult to determine what is causing your dog's cough and then determine which treatment is appropriate. Please take her to the vet so that appropriate diagnostics and treatment can be started.
