Dogs have a natural instinct to love, nurture and protect. In Philadelphia, a blind woman has found a new lease on life thanks to her new running mate. Across the world in Namibia, a Jack Russell is working as a super-nanny as she cares for a surprising array of species. In Kenya, a team of dogs are on daily patrol protecting endangered rhinos from poachers. Whilst in Glacier National Park in the US, a remarkable Border Collie dog is using her natural-born talent to protect people from wild animals and wild animals from people.
