I've talked to the BO, these are the options.
Cinny usually does fine with this current regime. The reason for the flare up was that we changed barns and dummy me didn't give him gastroguard during the change. He has only had this one flare up in 2 years. He shows, he trailers out to trails, he loves to be active and go places and never flares even without GG, so I thought he would be fine. I know now that with all that he does, changing barns is a big GG week from now on.
