Yes I've searched the forum and Google. My farm sits on loamy coastal sand and therefore our horses here are at an increased risk of developing sand colic. So as any well intentioned person with advice from a veterinarian, I gave sand clear. Henry has had 2 doses. And this morning I find him a bit sweaty even though it's 72 degrees outside, he's rolling and swishing his tail. He's still eating and drinking and looks perky and happy. So I'm just confused as to whether or not this is a self limiting condition related to the sand clear. I gave him a flake of fresh hay and he dug right into it. I guess I'm just paranoid. I don't want to push him into full blown colic with this preventative stuff if it's going to turn out not to work and do more harm than good.
