Coughing can be a symptom of many issues in our pets and some are more serious then others. The cough can stem from something occurring with the heart/vessels, lungs, airways, upper throat, or inside the chest/outside the lungs. There can be parasite causes (such as heartworms, lung worms, etc.), infectious causes (bacteria, viruses; unfortunately the Bordetella vaccine does not always prevent kennel cough as it is typically a complex of viral +/- bacterial causes, although typically there is exposure to other dogs in the history for this ailment), inhaled foreign material as you suggest, airway change (like tracheal (large airway) collapse), disease of the lung (such as bronchitis or pneumonia), and several other causes in various areas (inflammation, etc.). Is Stella otherwise normal (eating normally, playing with good energy)? If so this is a good sign. If you feel like she is otherwise not feeling well in association with the cough or the cough continues/worsens or is moist or productive it would be best to have her evaluated by your family vet. That way he or she can listen to her heart and lungs. A chest x-ray may also be recommended as an initial step.
