Dewlaps, the loose, fleshy folds of skin beneath a dog’s jaw, serve multiple purposes. They protect against neck injuries, aid in regulating body heat, and facilitate communication. However, they can also trap moisture, leading to infections and irritation. Breeds like the Bloodhound, Mastiff, and Newfoundland sport prominent dewlaps. Regular cleaning and sunscreen application are crucial for their care. If redness, swelling, or discharge occurs, veterinary attention is advised.

What is a Dewlap: A Unique Feature of the Canine Anatomy
Dogs, our beloved companions, exhibit a wide array of fascinating physical attributes, including the unique dewlap. But what exactly is a dewlap, and what role does it play in the canine world?
Defining the Dewlap
A dewlap refers to the loose fold of skin that hangs beneath a dog’s neck, often resembling a pouch. This fleshy appendage is a distinctive feature found in certain breeds, giving them an air of distinguished grace and functionality.
Essential Functions of Dewlaps in Dogs
Beyond its aesthetic appeal, the dewlap serves a vital purpose in canine anatomy:
-
Protective Layer: The dewlap provides an extra layer of protection for the dog’s neck against potential injuries from bites, scratches, or other external impacts.
-
Heat Dissipation: Dewlaps aid in thermoregulation by facilitating heat dissipation. When a dog pants, the rapid evaporation of moisture from the dewlap’s surface helps cool the body.
-
Communication and Emotion: Dogs communicate a range of emotions through body language and vocalizations, and dewlaps play a role in this process. The movement and position of the dewlap can convey information about the dog’s mood or intention.
Functions of Dewlaps in Dogs
Dewlaps, those flappy folds of skin under a dog’s chin, aren’t just aesthetic traits; they serve vital functions that enhance your furry companion’s well-being.
First and foremost, dewlaps provide a protective layer against injuries. When a dog engages in rough play or encounters unforeseen hazards, their dewlap acts as a natural shield, safeguarding the delicate tissues of their neck from bites, scratches, or other blunt force impacts. This protective function is particularly advantageous for puppies, whose necks are more vulnerable to injury.
Beyond physical protection, dewlaps play a crucial role in thermoregulation. Dogs, like humans, are susceptible to variations in body temperature. Dewlaps function as natural heat dissipators, helping dogs cool down on hot days. The increased surface area of the dewlap allows for evaporation of moisture, which creates a cooling effect.
Lastly, dewlaps serve as a communication tool for dogs. By flicking or twitching their dewlaps, dogs can express a range of emotions, including excitement, submission, or aggression. This nonverbal communication allows dogs to interact effectively with their owners and other dogs, fostering harmony and understanding within the canine community.
Benefits of Dewlaps: Nature’s Built-In Protection and Cooling System
Guarding Against Neck Injuries
Imagine your dog bounding through the woods, its body a blur of motion. Suddenly, it comes to an abrupt halt, its head caught between a fallen tree trunk and a sharp rock. In that heart-stopping moment, your dog’s dewlap steps in as a guardian angel.
This supple flap of skin acts as a natural protective layer, cushioning the delicate skin around the neck from the impact of such sudden collisions. It’s like an inbuilt shock absorber, minimizing the risk of severe injuries.
Assisting in Thermoregulation
As the sun beats down relentlessly, your dog’s dewlap plays a crucial role in combating heat stress. The thin, hairless skin allows heat to be dissipated into the surroundings, creating a cooling effect.
This is especially beneficial for breeds with thick, double coats, such as Newfoundlands and St. Bernards. By cooling the neck, the dewlap helps maintain the dog’s core temperature within a healthy range.
Drawbacks of Dewlaps
While dewlaps offer some benefits, they also come with a few potential drawbacks.
Moisture Retention and Potential Infections
- Dewlaps can trap moisture, creating a warm and humid environment that can foster the growth of bacteria and yeast.
- This can lead to skin infections, such as dermatitis, which can cause redness, itching, and discomfort.
Susceptibility to Irritations and Allergies
- The folds of the dewlap can act as a breeding ground for irritants and allergens, such as pollen, dust, and food particles.
- Contact with these substances can trigger allergic reactions or skin irritations, resulting in itching, redness, and swelling.
Breeds of Dogs with Dewlaps: Endearing Features
Dewlaps, those distinctive folds of skin hanging beneath a dog’s neck, are not only charming but also serve important functions. Several dog breeds proudly sport these notable dewlaps, each adding to their unique allure.
Among the breeds known for their dewlaps is the Bloodhound, an iconic hound with a wrinkled face and an exceptionally long dewlap that trails gracefully to the chest. This feature aids in heat dissipation, enabling the Bloodhound to navigate challenging environments.
The Newfoundland, a gentle giant, possesses a spacious dewlap that contributes to its imposing size. This breed’s dewlap not only provides protection from cold but also adds to its dignified appearance.
The Basset Hound, known for its exceptionally long ears, also boasts a prominent dewlap. Hanging low and loose, the dewlap helps absorb collar pressure during hunting expeditions and enhances the breed’s easygoing demeanor.
The Saint Bernard, a legendary mountain rescue dog, features a remarkable dewlap that extends past its shoulders. This thick fold of skin acts as a protective barrier against harsh weather conditions encountered while performing its heroic duties.
The Bullmastiff, a powerful breed, possesses a well-defined dewlap that complements its muscular frame. Not just an aesthetic enhancement, the dewlap serves as a guard against potential injuries during confrontations.
These are but a few examples of the many dog breeds that proudly display dewlaps. Each breed’s dewlap contributes to its distinct appearance and enhances its ability to thrive in various environments.
Care for Dewlaps on Dogs: Keeping Them Healthy and Protected
Dewlaps, those distinctive folds of skin beneath a dog’s neck, require proper care to ensure their well-being. Regular cleaning is paramount to maintain optimal hygiene and prevent infections. Use a soft, damp cloth to gently wipe away any dirt, debris, or excessive moisture that may accumulate within its folds. Ensure thorough drying afterwards to avoid moisture buildup, as it can create a breeding ground for bacteria.
Sun protection is also crucial for dewlaps, especially for dogs with lighter-colored skin. Extended exposure to the sun’s harmful UV rays can cause sunburn, inflammation, and even skin cancer. Apply sunscreen specifically formulated for dogs to the dewlap area before venturing outside for extended periods. Choose a sunscreen with an SPF of 15 or higher that provides broad-spectrum protection from both UVA and UVB rays.
By adhering to these simple care tips, you’ll help keep your dog’s dewlaps healthy, comfortable, and protected.
When to Be Concerned about a Dewlap
While dewlaps are generally a harmless feature, certain symptoms can indicate potential health issues that warrant attention. Dog owners should be watchful for the following signs:
- Redness: Excessive redness or irritation may indicate allergies, skin infections, or sun damage.
- Swelling: Swelling accompanied by pain or discomfort can be a sign of an abscess, trauma, or allergic reaction.
- Discharge: Unusual discharge, such as pus or fluid, can indicate an infection or other underlying condition.
- Pain: Pain or discomfort upon touching the dewlap may indicate an injury, infection, or other health issue.
- Infection: Signs of infection include redness, swelling, pain, and discharge. If left untreated, infections can spread and become severe.
If you observe any of these symptoms, it’s crucial to seek veterinary attention promptly. Early diagnosis and treatment can help prevent further complications and ensure your dog’s well-being. Remember, dewlaps may be a distinctive feature, but their health should be closely monitored to prevent any potential issues.
