Three types of assistance dogs from Japan: two guide dogs , a hearing dog and two mobility dogs , will show how they help disadvantaged people.

三种来自日本的协助犬——两只导盲犬、一只助听犬和两只介助犬将演示如何帮助残疾人。

Hearing dog: a dog trained to assist a deaf or hearing-impaired person by signaling the occurrence of certain sounds, such as a ringing telephone or doorbell.

被训练成通过发出类似于电话铃或门铃声等信号，给聋子或听力受损者提供帮助的导聋犬。

Hearing that reminded me of Queen Margaret's words in “Richard III”: “That dog, that had his teeth before his eyes, / To worry lambs and lap their gentle blood…” But he won't succeed.

这让我想起了玛格丽特女皇评价理查德三室的话，“恶犬，牙齿长在眼睛之前的动物，表面上可怜羊羔却在舔舐他的鲜血”。
