Dewclaws are those extra little toes found higher up on a dog’s leg, often resembling a miniature thumb. While most dogs have them on their front legs, and sometimes their hind legs, certain breeds are known for their absence. Understanding the presence or absence of dewclaws can provide insight into a breed’s history and purpose. So, what dog breeds don’t have dewclaws? Let’s explore this intriguing aspect of canine anatomy.
Certain breeds are genetically predisposed to lacking dewclaws, either on their front legs, hind legs, or sometimes both. This absence is often a breed standard, meaning it’s a desired trait within the breed. However, it’s important to note that even within these breeds, dewclaws can sometimes appear, highlighting the complex nature of genetics. We’ll delve into some specific examples of breeds known for their lack of dewclaws and discuss the reasons behind this characteristic. Whether you’re a seasoned dog owner or just starting your journey into the world of canine companionship, understanding these nuances can offer a deeper appreciation for the diversity and evolution of our furry friends.
Breeds Commonly Lacking Dewclaws
Several breeds are recognized for their lack of dewclaws, particularly on their front legs. This trait is often enshrined in their breed standards. The Norwegian Lundehund, for example, is a breed that can have up to six toes on each foot, including double dewclaws. However, the standard calls for removal of these extra digits on the rear legs. This historical practice is rooted in the breed’s unique role as a puffin hunter, where extra toes could be a hindrance when navigating rocky cliffs.
Other breeds where the absence of front dewclaws is common or even a breed standard include the Beauceron, a French herding breed, and the Pyrenean Mastiff, a large livestock guardian dog. While not entirely absent in these breeds, the frequency of dogs lacking front dewclaws is significantly higher compared to other breeds.

Why Do Some Breeds Lack Dewclaws?
The absence of dewclaws is often attributed to selective breeding. Over generations, breeders have selected for traits considered desirable for a breed’s specific function. In working breeds, for instance, dewclaws were sometimes perceived as a vulnerability, susceptible to injury or snagging. Therefore, dogs without dewclaws were preferentially bred, leading to a decrease in their prevalence within these breeds.
Do All Dogs of These Breeds Lack Dewclaws?
While certain breeds are known for the absence of dewclaws, it’s crucial to remember that genetics are complex. Even within breeds where the lack of dewclaws is a standard, some individuals may still be born with them. This variability underscores the intricate nature of inheritance and the ongoing influence of genetic diversity. It’s also important to note that dewclaw removal is a surgical procedure and should only be performed by a veterinarian.
Are There Health Implications Related to Dewclaws?
While dewclaws might seem like vestigial remnants, they do serve a purpose. They provide added stability, particularly when turning or running at high speeds. They also assist with gripping objects and climbing. In breeds where dewclaws are present, their removal can sometimes lead to complications, such as arthritis or carpal instability.
Conclusion
Understanding which dog breeds don’t have dewclaws and why provides valuable insights into breed history, purpose, and the complex interplay of genetics. While their absence can be a breed standard in some, it’s not a guaranteed trait in every individual. Remember to always consult with your veterinarian regarding any concerns about your dog’s dewclaws.
