Work like a dog
Meaning
To work extremely hard, tirelessly, and often for long hours.
Origin
Throughout history, dogs have been mankind's most dedicated laborers. From ancient times, they were bred for relentless tasks: herding livestock across vast fields, tracking prey through dense forests, pulling sleds through unforgiving snow, or guarding homes with unwavering loyalty. This tireless, often arduous, existence—characterized by long hours and instinctual devotion to duty—cemented the image of the working dog. By the 19th century, as industrialization increased demand for strenuous human labor, the phrase "work like a dog" emerged, capturing the essence of this ceaseless, hard effort, likening human toil to the uncomplaining and persistent diligence of these four-legged helpers.
