Horse Colic PLEASE HELP...NEW TO HORSES!!?

If he is still eating and pooping normally, then maybe the pain he's obviously in is not due to colic but to something else. In either case, this horse really needs to be seen by a vet ASAP. If he makes it through this episode, I would consider getting a new vet. Your vet should always make time to come see a horse in an emergency situation, or should have agreements with other vets to cover emergencies.
