Are guide dogs of great help to the blind? Blind people have difficulty moving. Guide dogs will help the blind people to go around obstacles such as water pools by making large detours to ensure that the blind people will not step on them. Crossing the road is based on the flow of people and vehicles. The situation is passed and taken to the destination.

Blind people have difficulty moving, and when traveling with a cane, the range of movement is very small. When a person goes out, he will inevitably bump into bumps. The goodness of a guide dog is reflected in its flexibility. It stands on the left hand side of the blind person and walks around. When crossing obstacles such as waterholes, they will make a large detour to ensure that blind people will not step on them; crossing the road is based on the flow of people and vehicles, and is aware of "principled disobedience", which means that it believes that the current intersection is not suitable for crossing the road If the blind person prompts it, it will refuse to obey. In addition, it will look at obstacles "in the air", such as branches.

After the guide dog goes to a place several times and tells the password, when the blind person tells the destination, it will take the blind person there. Therefore, when the guide dog and the blind person build trust in each other, the blind person will walk like It feels as safe as being supported by a friend. All of this has greatly expanded the scope of activities for blind people and increased the safety of travel.
