Re: Introducing Sweetie
Hello and welcome to the forum. Some vets have a preference for the twice a day dosing and do start out with that. Dr. Peterson in NYC a well known specialist in cushings prefers to start there. My personal internist, likes once a day, so I think often that is a preference.
The 20mg a day is perfect starting point and hopefully will just do the trick. Give it a few days before expecting to see results as every dog is different, as you already know. 10 days hopefully you'll see some subsiding of symptoms like eating/drinking excessively.
Coat and skin are two things that take the longest to turn around usually just because of the hair cycle timeframe. Some dogs never get the under coat back. Mine never did, but her over coat grew like crazy.
