As we all konw ,dogs are our best friends .Not like cat ,dogs are more loyal.They'll never let you alone,keep protecting you,till they die. Dog has many species.As to size, some of them are large dogs,more strong and fierce,such as Tibetan mastiff,Caucasian,and so on.some of them are medium sized,which are more balanced,for example ,Golden and Labrador.Besides, small dogs are also popular with human.I have my pomeranian for almost 1year ,named Aixi.She is a precious gift for me. Dog- themed movies keep creating box-office myth.Hachi is one of them,adapted from a real moving story.Meanwhile,the truth that dogs defende their masters from sudden attack,is proved all over the world.They are not only our pets,but also companion,family. 众所周知,狗是我们最好的朋友,不像猫那样,狗更加忠诚。狗永远不会让你孤单,一直保护着你,知道他离开我们。 狗有很多品种,对于体重来说,有大型犬,大型犬更加强壮,凶猛,比如藏獒,高加索。中型犬相比较更加均衡,比如金毛,拉布拉多。除此之外,小型犬也很受人类的欢迎。我有一只叫艾希的博美犬,对我来说,她是一份珍贵的礼物。 以狗为主题的电影持续创造票房神话,忠犬八公就是这样的,改编自一个真实感人的故事。同时,狗狗保护主人免受意外伤害的事实在全世界范围内被证实.他们不只是我们的宠物,更是我们的伙伴,我们的家人。 你看一下,或者写一下中文的,我来翻译。希望能帮到你~~
