What is a dewlap in rabbits?

A dewlap refers specifically to a fold of loose skin that is found under the chin of female rabbits, known as does. This characteristic is particularly prominent in some breeds and is a natural anatomical feature. The dewlap serves various purposes; it can help with thermoregulation, allowing the rabbit to cool itself, and it is also used during nesting periods as the doe pulls fur for nest building to provide warmth and protection for her kits.

Understanding the dewlap's characteristics can be crucial for proper care and management of does, particularly in breeding situations. It highlights the physical adaptations of rabbits related to their reproductive and maternal behaviors. This feature can also demonstrate health and weight conditions, as an overly large dewlap may indicate obesity, while a smaller dewlap is normal in leaner rabbits.
