Dogs have been bred by men on their different personalities basis to achieve specific functions, which have evolved with times: hunting, sheeping, rescue or guide dogs have adapted their natural instincts and abilities to their owner's needs. They excel in detecting things unnoticed to humans, as medical conditions, because of their better developed senses of hearing, smell and vision, combined with their emotional connection. Various working dogs and experiments are shown.

Dogs have evolved from their wild ancestor moved by a mutual benefit in interacting with humans. Same as them, they need confidence and security. They have substituted the wild wolf's herd for human families which have their own alpha member. They keep the team working instinct, only with more differentiated roles. If they are separated they will tend to come back. This team sense, more apparent in wild dogs as African lycaons, has been transformed in domestic dogs in their sensibility to their owner's needs and emotions and sense of protection and defence. We are presented with various examples and scientific experiments like robot interaction or oxitocin release. Human selection through breeding has strongly determined adaptations in size and character, and is still creating new varieties.
