“I’m looking forward to my vacation. I’ve been working like a dog all month to get this project done on time.”

Dogs work very hard. When we work hard, we compare ourselves to dogs.

Working dogs might herd sheep or search for people, such as survivors of a disaster or escaped criminals. Dogs will work hard for long hours. For example, guard dogs are on duty 24 hours a day. Dogs want to do a good job at their work and aren’t motivated by money. But in reality, even dogs need some rest.
