When you were in the village，the air in the country was clean and you watched the beautiful stars at night．However，it has been raining since you left the village．"You are a lucky dog!"If you heard of that，don't be angry．It doesn't mean"You are a dog．"Your friend just wants to tell you，"You are so lucky!"

Americans use many expressions with the word"dog"．People in the United States love their dogs and treat them well．They take their dogs for walks，let their dogs play outside with them and give their dogs good food and medical care．However，dogs without owners'care lead a different kind of life．The expression，to lead a dog's life，describes a person who has an unhappy life．

Dog expressions are also used to describe the weather．The dog days of summer are the hottest days of the year．A rainstorm may cool the weather．But they do not want it to rain too hard．They want it to rain cats and dogs．

If many people are competing for the same things，like good jobs．They will say，"We live in a dog﹣eat﹣dog world，"If they say a person has to work like a dog，it means he has to work very，very hard．Such hard work can make people dog tired．And，the situation would be even worse if they became sick as a dog．

However，not all dogs are compared to people in good ways．Some people are compared to dogs in bad ways．People who are not kind can be described as meaner than a junkyard dog．Junkyard dogs live in places where people throw away things they do not want．Mean dogs are often used to guard this property．They bark or attack people who try to enter the property．However，sometimes a person who appears to be meanand frightening is really not so bad．We say his bark is worse than his bite．

We live in a dog﹣eat﹣dog world，so we have to work like a dog．But never be mean dogs．When you fail，don't give up．I believe every dog has its day．
