My 28-year-old Quarter Horse gelding had a sudden onset of FFWS several years after acquiring him. This was ongoing for approximately two years. His symptoms were severe with water expulsion without manure 5-7 times a day. Manure was extremely soft without diarrhea. No other abnormalities or illness were observed. He was started on C2-Fecal Water at the end of November 2023. Within 3-4 days, firmer manure was noted and expulsion of water decreased to 0-3 times a day. This stayed stable for 2-3 weeks and I went from having to bathe him every 2-3 days to once every 10 days or so. His manure has become more consistent with normal formed balls with an isolated expulsion of water some days, again seeming mostly now to be connected to weather changes. All in all, his symptoms have decreased by 80-90%.
