My gelding is in good health, but any time we trailer somewhere he has a bout of loose poops bordering on diarrhea. It quickly resolves after we get home, but in the meantime he makes a mess of himself and the trailer. We have only ever done day trips, but I worry about when we start going to longer shows.
Anything I can do to help alleviate this? He already gets some probiotics in his TC30, but I could certainly add more the days before and during an outing if it would help. Would a dose of gastroguard help with the diarrhea, or is that really just to prevent ulcers?
