Perhaps you think an osteopath is a vet. In my book, an osteopath is not a DVM anymore than they are an MD. They have a license, at least with respect to humans, as DO. Not the same at all. I realize in some rural areas this may be all there is, but it is still not the same.
I would still do a fecal, that way you know what else there may be. It is cheap insurance, to me. I, personally, would call a DVM. (vet). JMHO. I prefer good scientific medically based advice, but perhaps that is because I am a nurse.
I also would question the history and how the horse has been treated previously..or not.
