My pet has the same thing wrong that he/she was just treated for. Can the veterinarian just prescribe the same medication that he/she did the last time?

Even though your pet may be showing the same symptoms as he or she did the last time, the problem may be different. Many diseases have similar symptoms, and we need to examine your pet to ensure that we correctly diagnose the cause. Also, for many recurring problems it is important for us to treat the underlying cause prior to starting medications such as cleaning and removing debris from the ear, clipping and cleaning skin lesions or properly expressing the anal glands.
