For dogs with Addison's disease, prednisone replaces the missing cortisol (a glucocorticoid) by mimicking its function, helping the body manage stress, metabolism, and inflammation, essentially acting as a lifelong hormone replacement for the adrenal glands that aren't producing enough, with the goal of maintaining normal function alongside aldosterone replacement (often with injections or Florinef), while vets carefully manage doses to avoid side effects like increased thirst, urination, and appetite.
