That's right! Horses can't burp, at least not the way humans do. They can't vomit or breathe through their mouths like humans do either. A horse's digestive system is a one-way street, unlike cattle and other ruminants who regurgitate food to re-chew it. Although they have a pretty efficient way of processing the tough fibrous foods that make up their forage, this long, one-directional system can cause problems that result in colic.1

Every horse on the North American continent is a decedent of European horses. Even the horses that we regard as "wild" are actually feral horses, whose ancestors escaped from captivity. Horses disappeared from the Americas more than 11,000 years ago, and there is ample fossil evidence that the horse's ancestors lived here previous to that.
