Kennel Cough
HOW IS IT TREATED?

Although most cases will go away on their own, we like to think we can hasten recovery with antibiotics to directly kill the Bordetella organism. Alternatively, Kennel Cough may be treated with cough suppressants to provide comfort during natural recovery. Or antibiotics and cough suppressants can be combined.
