Every dog has its day，也可以说成Every dog has his day，意思是“每个人都有自己风光的一天，人人都有得意之时”。这里的dog并不是其字面意思所说的“狗”，而是引申指普通人。这句话可以用来告诫某人不要小看别人，因为每个人都会有出头之日，风水轮流转。你也可以用这句话来鼓励身处低谷、情绪低落的人，安慰他们总会有时来运转的一天的。
—You look invigorative these days! 你最近看起来很有精神啊！—Thank you. Every dog has its day. 多谢。人人都有得意时嘛！
“汪星人”(dog)是人类的好朋友，所以人们在口语运用中也常常会用到它。下面列举几个最常用的表达。
1. Love me, love my dog. 爱屋及乌这个短语从字面意思来看，就是“爱我，就爱我的狗”，相当于我们常说的“爱屋及乌”，意指爱一个人就应该爱他的一切。例：It's a dog's life being a football manager. 当足球队经理实在是活受罪。例：—I managed to order the tourist group to Paris. 我总算报上去巴黎的旅游团了。—Wonderful! You're a lucky dog. 太棒了。你真是个幸运儿。例：The situation would be even worse if she became sick as a dog. 如果她病得很厉害，情况就会更糟糕。例：He seems to have gone completely to the dogs and spends all his time in the pub. 他似乎已经完全堕落了，整天泡在酒吧里。6. work like a dog 拼命工作，苦干例：I would work like a dog to make it. 为了达到目的，我要拼命苦干。
