"Top dogs" is a term often used to describe individuals or groups who are in a position of power, influence, or authority. However, there are several antonyms that can be used to describe those who are not at the top of the hierarchy. These antonyms could include "underdogs," "novices," "rookies," "junior members," "followers," or "subordinates." Each antonym highlights the idea of being lower or less dominant than the top dogs. Although these individuals may not hold the same level of power or influence, they still play important roles within their respective organizations or communities.
