Understanding the anatomy of our canine companions can be fascinating and helpful for their care. One particular feature that often sparks curiosity is the presence or absence of rear dewclaws. These small, elevated toes can vary in prominence and function across different dog breeds.
What are Rear Dewclaws?
Rear dewclaws, also known as “splay toes” or “dewclaws,” are an extra digit located on the inside of a dog’s hind leg, positioned higher up than the other toes. They are remnants of a fifth toe found in ancestral canines and are present in varying degrees across different breeds.
Why is this Topic Important?
Knowing which dog breeds have rear dewclaws can be beneficial for several reasons. It can help owners understand their dog’s unique anatomy, potential grooming needs, and susceptibility to certain injuries. Additionally, this knowledge can be helpful for breeders in maintaining breed standards and for veterinarians in diagnosing and treating paw-related issues.
What Dog Breeds Have Rear Dewclaws?
Dewclaws are the small, elevated toes located on the inner side of a dog’s leg, both front and rear. While many dogs have dewclaws on their front legs, the presence of rear dewclaws is less common and varies significantly across breeds.
Breeds with Rear Dewclaws
Some dog breeds commonly possess rear dewclaws, often referred to as “double dewclaws.” These include:
- Great Pyrenees
- Bernese Mountain Dogs
- Saint Bernards
- Newfoundlands
- Komondors
- Akbash Dogs
- Anatolian Shepherds
- Mastiffs
- Rottweilers
- Boxers
Breeds Without Rear Dewclaws
Conversely, many other breeds lack rear dewclaws entirely. This can be due to selective breeding practices or natural variations within the breed. Some examples of breeds typically without rear dewclaws include: (See Also: Why Does My Dog Stare In The Mirror)

Function of Rear Dewclaws
While rear dewclaws are not as prominent or functional as front dewclaws, they can still serve a purpose. In some breeds, they may assist with:
Traction and Stability
The extra toe can provide additional grip and stability, particularly on uneven terrain. This can be beneficial for working dogs who navigate challenging environments.
Braking and Turning
Rear dewclaws may contribute to a dog’s ability to brake and turn effectively, especially when running or maneuvering quickly.
Sensing Terrain
Some believe that rear dewclaws may help dogs sense changes in terrain and adjust their footing accordingly.
Health Considerations
Rear dewclaws can sometimes be prone to injury or infection, especially if they are long or hang down significantly. (See Also: Do Dogs Still Get Periods After Being Spayed)
Dewclaw Removal
In some cases, veterinarians may recommend removing rear dewclaws as a preventative measure to reduce the risk of injury. However, this is a controversial topic, and many believe that dewclaws should be left intact unless there is a medical reason for removal.
Recap
The presence of rear dewclaws varies widely among dog breeds. Some breeds commonly have them, while others lack them entirely. Rear dewclaws can provide benefits such as traction, stability, and braking assistance. However, they can also be susceptible to injury or infection. The decision to remove rear dewclaws is a complex one that should be made in consultation with a veterinarian.
