We've seen the headlines about the seven horses that died at Churchill Downs leading up to the Kentucky Derby. Mid-West Farm Report talks to Wisconsin School of Veterinary Medicine Dean Mark Markel to help understand the risks of competing in the sport, and what horse owners should be thinking about ahead of their competition season (rodeos, pulls, etc.) Markel is a certified equine surgeon. He says the risk for your competitive horse is going to vary depending on breed, age and type of sport. Thoroughbred racehorses have their own unique considerations.
