Taizo Shima

The zoologist says that when you hunt or search for underground bombs with a dog, the dog doesn't follow your barking orders. Short and reasonable words, which are backed up by such mutual trust to recognize the opponent as equal or higher and respect each other, are essential for you and the dog, which are different in direction and delicacy of feeling, to work together.
