So wait, let me get this straight. You didn't bring your dog in today so you can find out why he's scratching and what medicine you can give for it, you actually brought him in so you can find out how best to STOP the medicine that you already started???
By the way, the next time your dog has fleas and your husband the HUMAN dermatologist decides to prescribe a dose of prednisone high enough to treat lymphoma, please call first. That'll be $60, have a good day.
