A. If she is around a lot of other dogs such as in a kennel, dog park or doggie daycare situation, it is possible she may have contracted kennel cough, a very common upper respiratory disease. It can come in both viral and bacterial forms, however only the viral form is covered by vaccination. The viral form usually just has to run its course while the bacterial form or any secondary complications may require antibiotics.
Coughing can also happen if there is an issue with the throat, lungs or even heart, and may be a symptom of a problem there. You may see other issues such as wheezing, gasping for air, changes in activity level (not as active, tires out more easily) in addition to the coughing. Treatment varies depending on the cause, and additional testing such as blood work or X-rays may be needed.
If the coughing does not resolve after a few days, if it worsens, or if you see other signs of illness, then scheduling a veterinary appointment to look for underlying causes is best.
