Los perros han sido durante mucho tiempo nuestros más fieles compañeros. Pero no siempre fue así, y mirando a su pariente más cercano, el lobo, entendemos por qué. A través de los últimos estudios en genética, comportamiento y evolución, explicaremos cómo han llegado a ocupar un lugar tan importante en nuestras vidas. En este documental de PBS, los investigadores nos revelan cómo el ser humano ha conseguido domesticar a estos caninos durante miles de años, y cómo la inteligencia y los comportamientos actuales de los perros los han convertido en nuestros compañeros indispensables.

Además, este documental cuenta con el testimonio de científicos, genetistas, veterinarios e incluso arqueólogos que analizan la relación que tenemos con estos animales.
