That, is pretty much the standard procedure when this happens. I assume the vet explained why a lot of grass is a bad thing right now..Ok so the vet said that I should keep him locked up in the barn so he doesn’t he too much grass and limit the amount of water he takes. If she has trouble walking or anything like that then im supposed to call the vet immediately.
You may not be completely out of the woods, but so far, so good.
Usually, if colic doesn't appear in the first 12-24 hrs, then the next hurdle is hind gut toxins being released from dead and dying bacteria and then a hoof related problem properly called laminitis, which many (myself included) call founder.
good luck
