The Citadel Bulldogs' alternate logo history showcases the interesting journey the university's athletic brand has taken over the years. The alternate logos, just like the primary ones, have evolved significantly, each reflecting different aspects of The Citadel's heritage, athletic prowess, and identity.

The first known alternate logo, introduced in 2000, was a full-body white bulldog standing on its hind legs, wearing a blue Citadel uniform. Its right arm is raised in a saluting pose, a clear nod to the university's military culture. This logo was unique and immediately recognizable, setting it apart from the more common dog mascots of other institutions.

The university decided to update its alternate logo in 2013. The new logo depicted a more aggressive and dynamic bulldog, displaying an impressive level of detail. The bulldog, still clad in Citadel blue, was now in a fierce pose, its teeth bared and muscles rippling. This logo was meant to symbolize the strength, tenacity, and fighting spirit of The Citadel Bulldogs.

The most recent alternate logo, introduced in 2015, features a modern, stylized design of a bulldog's head in profile. The bulldog appears strong and formidable, with its intense gaze and powerful jawline. This minimalistic design is very different from the previous logos, but it encapsulates the Citadel's enduring values of strength and resilience in a fresh and contemporary way. As with every iteration of The Citadel Bulldogs' logos, this latest version continues to honor the university's past while looking forward to its future.
