I took Madison to the vet Tuesday, and she has kennel cough,she will be 7 weeks old tomorrow, The vet gave her a shot and put her on Clavamox twice a day, what I am needing to know is when a puppy has kennel cough will the symptoms get worse before they get better, because she is coughing more, and she sounds so pitiful when she coughs

, plus she has clear drainage coming from her nose now, is this to be expected before she gets better, or should I call the vet back? Thanks, Alicia
