Pepto Bismol to the Rescue!!!
Horse having gas colic? Two of my vets recommend using Pepto Bismol!
If you don't have the horse Bismal on hand run to your local Dollar Store and get a few bottles of this.
Ask your vet about the dosage for your horse first!
Works like a charm, but beware of the pink you may be weaing :)
You can also use after Bute use to soothe the stomach!
