"Never Turn Your Back on a Cow" - Dr. Jan Pol

The indefatigable vet has also starred in the eponymous "The Incredible Dr. Pol," on the Nat Geo WILD channel for 5 years. He shared some wisdom from his years as an animal healer with Boyd: "Don't leave your money laying around," so your dog doesn't eat change; Magnets can substitute as medical devices if your cow eats metal; and "Never turn your back on a cow."
