Episode Details:

Welcome to the Horse Episode! At the time of production, in the fall of 2020, the fires in Colorado were in our thoughts. Therefore, in this episode, we focus on the effects of smoke inhalation on horses, compare it to dust inhalation in the American Southwest, and look at management practices which equestrians can use to manage these conditions in their loyal steeds, with help from a few veterinary specialists. We also look at normal anatomy and physiology of horses and look into the literature available on smoke inhalation and dust in horses. Long story short, inhalations of particulates in dust and smoke can cause respiratory problems in horses, and the best ways to avoid those issues are to mitigate dust and smoke in the horses’ environment, as much as possible. Finally, for those who would like to help out equids (and their humans) who are suffering from wildfires and other difficulties, we talk about the AAEP Foundation, a philanthropic and volunteer organization. We hope you find this episode informative and enjoyable!
