Cough can be caused by an infection, heart problem or lung condition, it is important to first know the cause before treating it as treatment is different from condition to another. The most common disease causing cough is a viral infection called Kennel cough, this disease usually resolves without treatment within a couple weeks but if the cough is too severe it is recommended to go to the vet in order to get cough medicine and antibiotics.

    Poor Lily! This could be a sign of kennel cough, a highly contagious respiratory infection in dogs. I would have her seen by a vet in the morning. The vet can confirm if she does have kennel cough at the exam. While it's a self limiting disease, medications can help reduce the severity of the symptoms, and the vet can prescribe medications for her.
