Coming out of both nostrils would likely indicate a serious condition but that is not to say that coming out of one nostril indicates a less serious problem, if that makes sense. It is not a terrific prognostic indicator but coming out of 2 nostrils might mean a more systemic problem (like a clotting issue or something else). Really the best thing to do is to have them looked at, simply because if it IS a serious problem the consequences are so grave if it is unattended. Also, how are the horse's stools? Any darkening in color? What happens just prior to the bleeding, ie. Is it mostly after exercise or an exciting event??
