I continue to hear from people that it is challenging to convince horse professionals (vets, farriers, etc.) other ways of approaching horses' health. They find people know what they know, and changing what they know is uncomfortable. In this podcast, I review a text on horse health written in 1916 (108 years ago). I select some paragraphs to read and challenge people to ask, "Why?" I also look at horse health historically and from a worldwide perspective. We can limit and even prevent disease or lameness if we strive to understand why it occurs.
