Best friends come in all shapes, sizes, and species, from America to Australia, and from Britain to Zimbabwe. This six-part series looks at the cutest, funniest, and least expected animal relationships in the world, featuring animals that shouldn't get along but, for whatever reason, make their special bonds work. Join us as we travel the globe to meet an orphaned rhino calf and her dog and sheep companions, an orphaned baby kangaroo and a wombat, a zebra-donkey hybrid and two camels, and many more unusual but amazing friendships.
