The Lifesavers

S1 E2: Across the globe, dogs are saving the lives of passengers, families, and endangered wildlife, thanks to their remarkable natural abilities. In this episode, we watch Border Collies chase birds away from a South African airport to prevent potentially dangerous aircraft strikes. Then we head to Britain, where a Sprocker Spaniel uses her sense of smell to help rebuild the declining water vole population. Meanwhile in Namibia, an Anatolian Shepherd pulls double duty, protecting a goat herd from cheetahs... and cheetahs from livestock farmers.
