The article presents a literary review of scientific works related to the topic of the role of dogs in human life. 
The union of man and dog, as scientists report, dates back to ancient times, probably 14000 to 16000 years ago. In modern conditions, dogs occupy one of the main places next to people in almost all spheres of life - from protection of the rights and freedoms of citizens to sports with the use of dogs, as well as non-standard methods of treatment with the active participation of dogs. 
Dogs were the first animals domesticated by man. In this regard, they managed to overtake cows, sheep and goats. Of course, dogs were great guards and helpers during the hunt, but much more important was that you could communicate with them.
