visiting nurse for twenty years. She worked with poor immigrant laborers, providing preventive care and health education. Dock and Ethel Gordon Fenwick founded the International Council of Nurses in 1899, which offered a platform for nurses around the world to connect and improve public health. Dock took up the role of secretary. In 1907, Dock wrote two volumes of the History of Nursing with Mary Adelaide Nutting, which she revised and to which she added two more volumes alone in 1912. She went on to author several other books on the history of nursing as well, as she believed the position of nursing could only be solidified with accurate documentation of its history. Dock helped organize the former National Association of Colored Graduate Nurses in 1908.

She joined the Women's Trade Union League (WTUL). She participated in the New York shirtwaist strike of 1909 in support of the employees who walked off, most of which were women. In 1907, she joined the Equality League of Self Supporting Women and involved herself with the NY Women's Trade Union. As a nurse at the Henry Street Settlement, she also cared for poor immigrant laborers which led her to develop a sense of "strong sympathy with oppressed classes" that went against a common nursing belief at the time that their professionalization depended on their distance from these problems. During her work there, she understood the inextricable relationship between lifestyle and health. She and other public health nurses there became "chief authorities on immigrant health and public health reform in New York City".

Dock moved to Washington, D.C. in 1917 and joined the advisory council of the National Woman's Party, led by Alice Paul. Dock campaigned for women's suffrage by leading several protests, including pickets at the White
