How did dogs become man’s best friend?

A brief history of humans’ relationships with our furry friends

Dogs are not only man’s best friend; they are also his oldest one. Although historians agree that dogs were the first domesticated animal, there is debate on how long ago and where the friendship began.

Based on DNA evidence, most researchers believe that the furry, warm-nosed companion beside you descended from a group of gray wolves that has since become extinct1. Those canny canines figured out that if they hung with early hunter-gatherers rather than going it alone, they could live off what they could scavenge from the humans.

Scientists speculate that friendship bloomed when those humans began taking in wolf pups, which led to socializing them from infancy. And since wolves instinctively operate in packs with a clear hierarchy, humans easily assumed the role of alpha wolf, establishing themselves as Those Who Must Be Obeyed.

And there was a pay-off when man and tame wolf became a dynamic hunting duo. Humans’ skills and savvy combined with wolves’ speed and sense of smell turned them into complementary partners who tracked, captured, and devoured prey to their mutual benefit.

Humans offered wolves a reliable food source; tame wolves provided physical warmth and acted as early warning sentries when strangers or predators approached.

The animals that accepted this relationship evolved into more and more obedient companions until, many generations later, we had domesticated dogs and their feral gray wolf forbears died out.

How dogs are like wolves

  • Our pets still share many traits and instincts with their wild ancestors. Both:
  • Rely on their senses to understand the world
  • Guard their master’s home
  • Defend their territory
  • Scavenge when left to their own devices
  • Bury bones if given the opportunity

How dogs are unlike wolves

Despite a close genetic makeup, gray wolves and domestic dogs are dissimilar1. Dogs:

• Have foreheads that are more domed than wolves’

• Have smaller skulls, brains, teeth, and paws compared to equally-sized wolves

• Have tails that tend to curl upwards, unlike wolves’

• Relish having a job to do, from herding livestock to helping the blind
