I never knew there were so many ways people and animals work together. Really fascinating and fun to watch. This series goes all over the world to find stories of different kinds of animals that work with people. Some of them (like the rescue dogs and police horses) are familiar. But most of this series is about the unusual examples - like seals that dive to recover missiles and monkeys that guard trucks in India. For me, the stranger the story, the better. I like the stuff about leeches that heal wounds and the pig that finds truffles (funny). Anyone who wants to see the weirdest, wildest working animals - man, this is it.
