A. The partnership between humans and dogs began perhaps 14,000 years ago. Our first interactions may have occurred when wild dogs were attracted to human garbage, or humans may have acquired the puppies of wild dogs and trained them to be obedient pets. By means of the careful selection of dog parents, humans have been able to create a wonderful variety of dogs with plenty of talents and many different looks.

B. When did this remarkable partnership start? We know now that the wolf began working with people in the distant past. Over the years, the wolf became the talented domestic pet we know as the dog. There are plenty of theories, but the real reason why humans acquired dogs is still unknown. It might be a hunting partnership, companionship or a type of friendship. For 14000 years the dog has played an important role in human societies. It’s a partnership that’s likely to continue for many years to come.

C. Dogs are often known as man’s best friend. Many societies have them as pets or rely on them to perform a variety of tasks. The story of man and dog is a complex story that goes back thousands of years and will almost certainly go on for thousands more. Dogs interact with humans in a variety of ways. Dogs such as border collies are trained to herd livestock such as sheep. Huskies pull us through some of the coldest and the most dangerous places on Earth.

D. Dogs were probably first attracted to humans by the smell of our garbage. Nowadays, the governments of many countries have a use for those powerful noses that is beneficial to all who fly in airplanes. There are special trains for dogs to smell bombs on planes and in passengers’ luggage. For example, beagles perform their duties at airports, where their sense of smell helps them to find drugs and other illegal items in people’s luggage.

E. Dogs have a sense of smell 1,000 times more powerful than our own. This means they can search for people who are lost under deep snow, or under the debris of a collapsed building or deep in forest. You can find dogs in rescue services of many countries. A lot of lives were saved by dogs after the earthquakes and explosions in different parts of the world.

F. Special trained dogs help to ease the lives of thousands disabled people. They lead the blind people, for example. At the National Institutes of Health the dogs visit children who are fighting deadly diseases. They brighten patients’ days with love and give children a chance to exercise and help them to stay strong during their long hospitalization.

G. Whether as workers or objects of affection, dogs have certainly proven themselves to be beneficial to humans in many ways. For many, the dog is also an obedient companion and friend. In some families dogs are treated like a child. People carefully prepare special meal; give them the healthiest, most wonderful life possible for as long as possible. For single people, dogs are the best way to escape loneliness. At the same time, their special place as ‘man’s best friend’ has allowed dogs to survive in a human world.
