The Protectors

S1 E4: Dogs have a natural instinct to love, nurture, and protect and when it comes to caring for people, watching over wildlife, or defending endangered species, these four-legged guardians are eager to lend a paw! In this episode, we meet Gracie, a Border Collie who protects humans from wild animals and wild animals from humans at Glacier National Park, then travel to Kenya, where Diego, a Belgian Malinois, guards the rhinos at Ol Pejeta Conservancy. We also travel to Philadelphia, where a Labrador named Iris helps the visually impaired go jogging.
