关于狗狗你不知道的10件事

2. Scaredy Cat
胆小鬼

A frightened dog will put its tail between his legs because it cuts off the scent glands in its anal region which a very vulnerable part of the anatomy. Since the anal glands carry personal scents that identify the individual dogs, the tail between the legs action is the dog’s equivalent of insecure humans hiding their faces.
受惊的狗狗会将自己的尾巴夹在两腿之间，因为这样可以切断它肛门区的气味腺，肛门区是解剖学中一个非常脆弱的部位。因为气味腺携带了能识别狗狗的自身气味，所以狗将尾巴夹在两腿之间的行为就等同于害怕的人类遮盖自己的脸。
