Here is a thread about Lisa's pup Piccolo....maybe it will help you....
I do know that with cutaneous vasculitis the meds are ultra important and must be given beyond the point that the pup is no longer showing symptoms. My son's pup was on prednisone for I believe four weeks. I might be able to find a thread about it as I was caring for her when she started getting bad.
