Many people believe that dogs have a seventh sense. Before the earthquake dogs will run around barking before people feel the tremor; many owners say they are a few hundred meters away from home, dogs have felt their return message; in foggy weather, we are lost, dogs can find the direction to accompany us safely home. Dogs really have a seventh sense? This question I can not answer, but I can tell you scientifically how the dog’s vision, hearing, taste, smell and other aspects of the sensory system. Dogs developed sense organs 1 vision: dogs can observe movement at a great distance. The dog’s eyes on both sides of the head, which is its special place, so its field of vision can reach 250-290 degrees (the human field of vision is only 220 degrees), which helps it to better observe the surrounding environment, so as to find prey. 2 Hearing: Dogs can hear sounds from a great distance. They prick up their ears, turn in the direction of the sound source, and determine the exact location of the sound from the face. It is the collaboration of many ear muscles together to complete this action. 3 sense of smell: dogs can smell and distinguish between odors even at very low concentrations. Dogs have an average of 200 million olfactory cells, and their nose and tongue work together to achieve their long sense of smell. By “deep sniffing”. Dogs are able to gather important scent information. 4 Taste: It is not certain that dogs have a well-developed sense of taste. Dogs have fewer taste papillae on their tongues than we humans do. So some people say that dogs can’t distinguish between sweet and sour, but of course, scientists have to tell us the answer in more detail. Dogs have a powerful sensory system that allows them to help humans in drug interdiction, search and rescue, guide the blind, and so on. There are many, many dogs in the master before the danger to the master warning; in the master in danger would rather sacrifice themselves to rescue the master; in the master after the danger to accompany the master.

Before the earthquake, dogs will run around barking before people feel the tremor; many owners say they are still a few hundred meters from home, dogs have felt the message that they are back; in foggy weather, when we lost our way, dogs can find the direction to accompany us safely home.
