Dr. Melanie Barham talks to Dr. Stephen Schumacher, the Chief Administrator of Equine Drugs and Medication Programs for the United States Equestrian Federation (USEF), and Dr. Yves Rossier, president of the vet commission at the Pan Am Games and head of Equine Canada medication control committee. They discuss what veterinarians practicing on show horses should know, how to keep up to date on the rules in both Canada and the US, and why it matters for the welfare of the horse. We also discus some recent research on GABA and gabapentin in horses.
