Mia has been on 5mg of pred every other day for over a year now. She started at 50mg almost 2.5 years ago, we brought her down slowly and at one point she was on both pred and imuran.
She does have a very thin silky coat, we usually put jammies on her in the winter time. Unfortunately in her case every time we try to take her completely off of the pred, she flares back up, so we have accepted that she will probably have to take it for the rest of her life. I know it can cause problems with long term use, but it is a hard decision to make when we are thinking about long term pred usage vs. possibly losing her without it.
