Most dogs in the United States seem to have an easy life. They sleep a lot and get fed often.
People take their dogs for a walk two times a day and also let them play outside.
Dogs get medical care when they are sick or injured. What a great life! Right?
Well, we say people with a similar, carefree existence enjoy a “dog's life.”
They have no troubles or responsibilities. They can come and go as they please, sleep all day, and never have to work.
But not everyone has it so easy. In fact, 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 to be successful, a person has to “work like a dog.” This means they have to work very, very hard.
