Dogs from the Upper Paleolithic to the present day

The role of dogs was not limited only to help in hunting. In the XIV century BC e., during the Egyptian-Syrian wars, fearless dogs did not leave the chariot of Tutankhamun, fiercely attacking enemy troops.
The Chinese emperors wore the arms of their broad Pekingese kimonos. If the ill-wisher dared to raise his hand to the august person, the brave guard suddenly appeared from his clothes and grabbed the wrist of the enemy.

Sense organs, emotions and intelligence
The dog’s perception of the world is fundamentally different from the human. With 150 million olfactory receptors in its nose, four-legged pets sense odors that people don’t even know about. The hearing of animals is well developed: they pick up sounds made by a source remote at a distance of 40 m, and ultrasonic waves. The range of frequencies heard by the dog reaches 40,000 Hz.
Less developed in dogs is vision that does not play a major role in animal life. An adult dog is able to see the owner only from a distance of 40 m. The tetrapods lack a multi-colored vision of the world: they recognize only white, yellow, gray and blue tones. Read our article: How do dogs see?
