Rabbits are one of the most fascinating and beloved creatures in the animal kingdom, and their unique physical characteristics have always sparked curiosity among animal enthusiasts and scientists alike. One of the most intriguing features of rabbits is their dewlap, a flap of skin that hangs from their chin. But have you ever wondered why rabbits have dewlaps in the first place? Understanding the purpose and significance of dewlaps can provide valuable insights into the biology and behavior of these adorable creatures.
What is a Dewlap?
A dewlap is a flap of skin that hangs from the chin of a rabbit, typically found in female rabbits. It is a distinctive characteristic that sets them apart from other mammals. The dewlap is made up of skin and fatty tissue, and its size and shape can vary depending on the breed and age of the rabbit.
The Purpose of Dewlaps
So, why do rabbits have dewlaps? The answer lies in their evolution and reproductive biology. Dewlaps play a crucial role in the lives of female rabbits, particularly during mating and nursing. In this article, we will delve into the fascinating world of rabbit biology and explore the reasons behind this unique feature.

Why Do Rabbits Have Dewlaps?
Rabbits are known for their cute and fluffy appearance, but have you ever wondered why they have a flap of skin under their chin? This flap of skin is called a dewlap, and it’s a unique feature that sets rabbits apart from other animals. In this article, we’ll explore the reasons behind why rabbits have dewlaps and what purpose they serve.
What is a Dewlap?
A dewlap is a flap of skin that hangs from the chin or neck of a rabbit. It’s a loose, wrinkled piece of skin that can be found in both male and female rabbits. Dewlaps can vary in size, shape, and color depending on the breed and age of the rabbit. Some rabbits have small, barely noticeable dewlaps, while others have large, prominent ones.

Theories Behind the Dewlap
There are several theories as to why rabbits have dewlaps. While we can’t know for certain, here are some of the most popular theories:
-
Protection from the Elements: One theory is that the dewlap serves as a protective barrier against the elements. Rabbits live in a variety of environments, from hot deserts to cold forests, and the dewlap may help to shield their skin from extreme temperatures, wind, and sun.
-
Communication and Social Status: Another theory is that the dewlap plays a role in communication and social status. Rabbits use body language to communicate with each other, and the dewlap may be used to signal dominance, submission, or reproductive status.
-
Thermoregulation: Some scientists believe that the dewlap helps rabbits regulate their body temperature. The loose skin may allow for better airflow and heat dissipation, helping rabbits to stay cool in hot weather.
-
Evolutionary Remnant: Another theory is that the dewlap is an evolutionary remnant from a common ancestor. Rabbits share a common ancestor with other lagomorphs, such as hares and pikas, which also have dewlaps. The dewlap may have served a purpose in the past, but is no longer necessary for modern rabbits.
Functions of the Dewlap
While we can’t know for certain why rabbits have dewlaps, there are several functions that the dewlap may serve:
-
Food Storage: Rabbits are herbivores, and they need to eat constantly to stay healthy. The dewlap may provide a convenient storage space for food, allowing rabbits to stash away tasty treats for later.
-
Water Storage: In arid environments, water is scarce, and rabbits need to conserve it. The dewlap may help to store water, allowing rabbits to survive for longer periods without drinking.
-
Protection from Predators: Rabbits have many predators, from hawks to foxes. The dewlap may provide a distraction or a decoy, drawing predators away from the rabbit’s vital organs. (See Also: What Are Young Rabbits Called)
-
Scent Marking: Rabbits use scent marking to communicate with each other. The dewlap may provide a convenient surface for scent glands, allowing rabbits to leave their scent on surfaces and objects.
Breeding and Reproduction
The dewlap may also play a role in breeding and reproduction. In some breeds, the dewlap is more prominent in males, and it may be used to attract females or to signal dominance. In other breeds, the dewlap is more prominent in females, and it may be used to signal reproductive readiness.
| Breed | Dewlap Characteristics |
|---|---|
| Rex Rabbit | Large, prominent dewlap in males |
| Holland Lop | Small, barely noticeable dewlap in females |
| English Angora | Long, fluffy dewlap in both males and females |
Health and Hygiene
The dewlap can also be an indicator of a rabbit’s health and hygiene. A clean, well-groomed dewlap can indicate good health, while a dirty, matted dewlap may indicate poor health or hygiene.
Rabbits are prone to certain health issues, such as dental problems and respiratory infections, which can affect the dewlap. Regular cleaning and grooming of the dewlap can help to prevent these issues and keep the rabbit healthy.
Conclusion
In conclusion, the dewlap is a unique and fascinating feature of rabbits. While we can’t know for certain why rabbits have dewlaps, there are several theories and functions that the dewlap may serve. From protection from the elements to communication and social status, the dewlap plays an important role in a rabbit’s life.
By understanding more about the dewlap, we can better care for our rabbit friends and appreciate their unique characteristics. Whether you’re a seasoned rabbit owner or just a rabbit enthusiast, the dewlap is definitely worth learning more about.

Frequently Asked Questions about Dewlaps in Rabbits
What is the purpose of a dewlap in rabbits?
A dewlap is a flap of skin located under the rabbit’s chin, and its primary purpose is to help keep the rabbit’s face and chin clean. When a rabbit eats, it often dips its head into its food, and the dewlap acts as a barrier, preventing food particles from getting stuck to the rabbit’s fur. Additionally, the dewlap also helps to collect saliva, which the rabbit can then use to clean its face and paws.
Do all rabbits have dewlaps?
Not all rabbits have dewlaps, although it is a common feature in many breeds. Some rabbit breeds, such as the Netherland Dwarf and the Polish, do not have dewlaps. The presence or absence of a dewlap is often determined by the rabbit’s genetics and breed characteristics.
How do I clean my rabbit’s dewlap?
Cleaning your rabbit’s dewlap is an essential part of its grooming routine. You can use a damp cloth or cotton ball to gently wipe away any dirt, debris, or food particles that may have accumulated on the dewlap. Be sure to clean the area carefully to avoid irritating the skin or causing any discomfort to your rabbit.
Can a dewlap be a sign of health issues in rabbits?
In some cases, a dewlap can be an indication of certain health issues in rabbits. For example, if the dewlap is excessively wet or dirty, it may be a sign of dental problems or digestive issues. Additionally, if the dewlap is red, swollen, or inflamed, it could be a sign of an infection or skin irritation. If you notice any unusual changes in your rabbit’s dewlap, it’s always best to consult with a veterinarian to rule out any underlying health issues.
Can I trim or remove my rabbit’s dewlap?
It’s not recommended to trim or remove your rabbit’s dewlap, as it serves an important purpose in the rabbit’s grooming and feeding habits. Additionally, trimming or removing the dewlap can cause discomfort and stress to the rabbit, and may even lead to skin irritation or infection. If you have concerns about your rabbit’s dewlap, it’s always best to consult with a veterinarian or experienced rabbit breeder for advice.
