Respiratory Infection
You part of the body's attempt to eliminate the residue left by infection in the airway, suppressing this natural response does not make sense to me. If your puppy is not improving or especially if his attitude or appetite are affected you should contact your veterinarian. After examination your vet may choose to begin antibiotic therapy. While a single 10 day course of antibiotics defeats many infections it is no surprise that some puppies require treatment for longer periods. If your puppy has improved on the antibiotic it should be continued, if he has not improved your vet may change to a different antibiotic. It is sometimes necessary to continue therapy for several weeks. In my experience clavamox is often disappointing. Please keep me informed.
