This inspiring series celebrates the human-animal bond by telling uplifting stories about shelter pets and the people that help them. This episode, hosted by anthropologist Jane Goodall, features shelter dogs that are trained to protect endangered species. We follow the dogs from the day they are rescued to their deployment in Zambia where they are helping prevent the poaching of elephants and rhinos. Also: a high school cross country team takes shelter dogs for a run as part of their practice.
