Which gender of rabbit typically has a dewlap?

The dewlap is a fold of skin located under the chin and is more prominent in female rabbits, known as does. It serves several purposes, including helping with thermoregulation and providing a nurturing space for the mother to groom and care for her young. Does often develop this feature as they mature, particularly during breeding season when hormonal changes occur.

In contrast, while bucks (male rabbits) do have some skin under their chin, they typically do not develop a dewlap of the same size or prominence as does. The dewlap is not a common feature found in both genders, nor is it absent in both, which further clarifies why the specific choice identifying does as having a dewlap is accurate.
