Dr. Saundra TenBroek, from the University of Florida, and first time guest to the show, shares her advice on deworming horses with science and biology in mind.  We've learned a lot over the years, and your parasite control program may look a bit different than it did a few years ago.  Find out which  horses may not need to be dewormed as much as we used to, and how to find out for yourself!
