Dogs are truly man's best friend. From the moment they were domesticated, they have been working dogs—companions, protectors, and sometimes even lifesavers.

This documentary looks into the "Man's Best Friend" relationship and the unique roles dogs are capable of filling for their handlers. We learn about some of the most common working dog breeds and their specialized skillsets. We also explore what it takes to be a handler in such a relationship and how these relationships develop over time.
