Hi there. Without knowing what specific medications she's taking, it's hard to say. But, if she is on a steroid such as prednisone, this can certainly cause increased drinking and urination, and will cause some dogs to have accidents in the house. I would suggest calling your veterinarian tomorrow to discuss your concerns. He/she may recommend decreasing her steroid dose (if she's currently taking one), or switching to a different medication to help with these side effects.
