How the dog became a companion animal
The dog probably descends from the gray wolf, with DNA research having shown that all modern dog breeds find their origin in this single wolf species. Scientists believe that domestication began when certain wolves were less shy and settled near human settlements, attracted by food scraps. These wolves had a genetic advantage: they were more docile and could better cope with the presence of humans.
The first demonstrable relationship between the wolf and humans is around 10,000 to 15,000 years ago, although some recent archaeological findings suggest that this bond may have originated as long as 30,000 years ago. Fossil remains of dog-like animals have been found in Siberia, the Middle East, and Europe, indicating that domestication possibly occurred in multiple places simultaneously. It is not certain whether humans came to the wolf or vice versa, but the most accepted theory is that it was a gradual process of mutual adaptation.
Both benefited from the resulting situation: the wolf was used by humans for hunting, where its sharp senses and speed were indispensable for tracking and chasing game. Additionally, the dog was deployed for herding livestock, guarding property, and warning against enemies or predators. Archaeological evidence shows that early dogs were also used to pull sleds in cold regions. Humans, in turn, ensured that the wolf always had food, protection from other predators, and a safe place to rest.
The wolf is a very social animal. Like humans, it lives in groups (called packs), with a social hierarchy where certain wolves assume leadership. This natural hierarchy made communication between humans and dogs possible, as both species understand how a social structure works. Interestingly, over thousands of years of evolution, dogs have developed the ability to interpret human facial expressions and gestures - something wolves can barely do. This makes the animal suitable and attractive as a companion animal, with the wolf viewing the human as leader.
People began to impose different requirements on the wolf's behavior and appearance. Selective breeding ensured that certain characteristics were reinforced: some dogs became smaller and more playful, others larger and more protective. In different cultures, specialized dog breeds developed for specific tasks. Thus emerged hunting dogs in Europe, herding dogs in Asia, and guard dogs in the Middle East. Notably, during this domestication process, physical changes also occurred: dogs acquired floppy ears, curled tails, and spotted coats - characteristics that rarely occur in wild wolves.
During the Middle Ages, people began to regard the dog as a kind of status symbol. Noble families kept specific breeds for hunting and display, with the ownership of certain dogs indicating your social position. Small lap dogs became popular among the European nobility, while large hunting dogs such as greyhounds were reserved for the elite. The dog provided humans with prestige and was even depicted in family portraits and coats of arms.
Since then, the number of dog breeds began to increase enormously. Where there were only a few dozen recognized breeds around 1800, there are now more than 400 officially recognized dog breeds worldwide. Dogs were bred for size, length, color, head shape, behavior, and cuddliness. From the minuscule Chihuahua of only 1.5 kilograms to the imposing Saint Bernard of up to 90 kilograms - the diversity within a single species is extraordinary. Modern genetic research has shown that this enormous variation came about in just a few thousand years, making the dog one of the most successful examples of human-guided evolution. This continues to this day, with breeders striving for both health and welfare as well as specific breed characteristics.
Thus we arrive with modern
