People in theUnited Stateslove their dogs and take good care of them. They take their dogs for walks,let them play outside and give them good food and medical care. However,dogs without owners to take care of them lead a different kind of life. The expression,to lead a dog's life,describes a person who has an unhappy life.

Some people say we live in a dog-eat-dog world. That means many people are competing for the same things,like good jobs. They say that a person has to work like a dog to be successful. This means they have to work very,very hard. Such hard work can make people dogtired. And,the situation would be even worse if they became sick as a dog.

Husbands and wives use the word doghouse when they are angry at each other. For example,a woman might get angry at her husband for coming home late or forgetting some important days. She might tell him that he is in the doghouse. She may not treat him nicely until he says sorry. However,the husband may decide that it is best to leave things alone and not make more problems. He might decide to let sleeping dogs lie.

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 we do not want it to rain too hard. We do not want it to rain cats and dogs.
