A dog is man"s best friend,before human watchdogs,in modern society,they became pets; or visually impaired second pairs of eyes and it will make you happy,you will hear what you say watchdogs,unhappy things oh.

I have a lovely dog. Its name is YoYo. I like it very much. It has two big ears, two big and bright eyes.

Its hair is brown. It has come to my home for a year. It has become a part of my family. It has its own house, but it likes to sleep under my bed, play in my house. I like talking to it, because its a friend worth of trusting.

I would like to share my happy things with it. When I am sad, talking to it makes me feel good. I am happy to have such a lovely friend.

One of the animals that help people a lot is the dog. In some countries, dogs pull wagons.

In the cold north, dogs pull sleds.　There are other ways that dogs help us, too. Policemen use them to look for missing people. Soldiers use them to carry letters and medicine .

On farms, dogs take care of sheep and keep them in the fields. At night, they take the sheep home. Dogs help the blind with work. Some dogs are good and kind. Some dogs are good at another skill.　　

有一種是狗的動物給人們提供很多幫助。在一些國家,狗拉馬車。

在寒冷的北方,狗拉雪橇。狗還有其他的方法可以幫助我們。警察使用它們來尋找失蹤人員。士兵攜帶信件和醫學中使用它們。

在農場,狗看守綿羊，讓它們待在田地裡。晚上,它們把羊帶回家。狗幫助盲人工作。有些狗很友好而且善良。有些狗擅長另一項技能。

它用水汪汪的大眼睛，盯著來往的行人；它用靈敏的耳朵，聽著門口的動靜；它用汪汪直叫的嘴巴，添著骨頭，還不時警惕的豎起耳朵，閉閉眼睛，主人經過還乖巧的叫幾聲，偶爾還能把偷東西的小孩抓到…… 它，就是狗！
