The vital role it plays
Dogs have been very helpful in rescue efforts on land. Due to the effort of well-trained search and rescue dogs, thousands of human lives are saved every year.
Because of their small size and sharp sense of smell, dogs can locate survivors much faster than humans can. However, it takes much time and effort to train them. Also, dogs may lose their sensing ability if they work too long. In that case, they have to retire.
