Rear dew claws in dogs are a unique anatomical feature that has piqued the curiosity of dog enthusiasts and breeders for generations. While the majority of dogs possess front dew claws, rear dew claws are a relatively uncommon occurrence. These small, seemingly vestigial appendages are found on the inside of a dog’s leg, just above the paw. This article delves into the world of rear dew claws in dogs, exploring their history, evolution, and the specific breeds that naturally possess them.
Dew claws, also known as vestigial toes, are the small, non-weight-bearing digit located on the inside of a dog’s leg, similar to a thumb in appearance. While front dew claws are more prevalent and usually are seen on all dogs’ front legs, rear dew claws are less common and are seen only in specific breeds.
Rear dew claws are essentially the equivalent of a dog’s thumb and are usually found higher up on the leg, resembling a small bump or additional toe. While they don’t serve a significant functional purpose for most modern dog breeds, rear dew claws are considered to be a remnant from a time when dogs had different physical and behavioral characteristics.
The presence of rear dew claws in dogs has sparked debate among evolutionary biologists and canine enthusiasts. These vestigial digits are believed to have evolved from the days when dogs exhibited more diverse physical traits and behaviors, including a more arboreal lifestyle. In these ancestral dogs, rear dew claws may have played a role in climbing and grasping, much like a prehensile thumb in primates.
Over time, as dogs’ lifestyles and physical characteristics evolved, rear dew claws became less essential for survival. Consequently, the presence of rear dew claws in modern dog breeds varies widely and is most prevalent in certain lineages. Despite the diminishing functional significance, rear dew claws have persisted in some breeds, serving as a testament to the diverse evolutionary paths dogs have undergone.

Most dog owners are familiar with the concept of dew claws, which are the small, vestigial claws located on the inner side of a dog’s front legs. However, fewer people are aware that some dog breeds also possess rear dew claws. Rear dew claws are essentially additional claws located on the hind legs of a dog, above the standard paw.
The presence of rear dew claws in certain dog breeds has sparked both curiosity and controversy among dog enthusiasts. While some appreciate the unique characteristic, others question its purpose and potential health implications.
The presence of rear dew claws in dog breeds has been a subject of debate among breeders and enthusiasts. Some believe that rear dew claws are a natural and beneficial trait, while others argue that they may cause health issues and should be removed.
Proponents of rear dew claws argue that they can serve a practical purpose. For instance, in breeds used for herding or hunting, such as the Anatolian Shepherd or Great Pyrenees, rear dew claws can aid in gripping the ground and providing stability during intense physical activities. In these situations, the rear dew claws act as an additional "thumb" for the dog, providing increased dexterity and grip.
On the other hand, detractors point out that rear dew claws can be easily snagged or torn, potentially causing injury or discomfort to the dog. This is particularly concerning in breeds that are known to be highly active or have a propensity for certain physical activities, such as agility or hiking. Moreover, rear dew claws can also be an aesthetic concern for dog show participants, as they may deviate from breed standards.
Ultimately, whether or not rear dew claws are a desirable trait in dog breeds depends on personal opinions and the specific needs of the dog. It is important for owners and breeders to consider the functional purposes and potential health concerns associated with rear dew claws before making any decisions.
While the presence of rear dew claws may be a matter of debate, there is evidence to suggest that they serve functional purposes in certain dog breeds. Here are some of the potential functions of rear dew claws:
Gripping and Stability: In breeds that are used for activities such as herding, the rear dew claws can act as an anchor, allowing the dog to have better stability and grip on the ground. This can be especially useful when traversing uneven or slippery terrain.
Climbing: Some dog breeds, such as the Briard or the Beauceron, are known for their climbing abilities. Rear dew claws can assist these dogs in climbing trees, fences, or rocky surfaces by providing added leverage and grip.
Preventing Injury: Rear dew claws can act as a stabilizer when a dog is running or turning quickly. They can help prevent injuries such as sprains or strains by providing additional support to the dog’s leg.
Defense Mechanism: In a defensive situation, a dog may instinctively use its rear dew claws as a weapon to fend off an attacker. While this function may not be as common or necessary in domesticated dogs, it can still be observed in certain breeds.
It is important to note that not all dog breeds possess functional rear dew claws. In some breeds, the dew claws are not well-developed and may not serve any practical purpose. It is necessary to understand the specific breed’s characteristics and requirements before determining the significance of rear dew claws.
The presence of rear dew claws in dog breeds can be attributed to genetics. Different breeds have different genetic predispositions for the development of dew claws, including rear dew claws.
Rear dew claws are believed to be a throwback to an earlier evolutionary stage when dogs had more toes. Ancient dog breeds, such as the Basenji or the Norwegian Lundehund, still retain this primitive trait. It is thought that over time, as dog breeds were selectively bred, some lost their rear dew claws while others retained them.
The presence or absence of rear dew claws is determined by a dominant or recessive gene. If a dog inherits the dominant gene from both parents, it will have rear dew claws. Conversely, if a dog receives the recessive gene from both parents, it will not have rear dew claws. If a dog inherits one dominant and one recessive gene, it may or may not have rear dew claws, depending on the specific combination.
It’s important for breeders to understand the genetics behind rear dew claws in order to selectively breed for or against this trait. For those who appreciate the functional purposes of rear dew claws, it is essential to breed dogs with the dominant gene to ensure that the trait is passed on to future generations. Conversely, breeders who wish to eliminate rear dew claws from a breed can focus on breeding dogs with the recessive gene.
While rear dew claws can serve functional purposes in certain dog breeds, they can also pose health risks if not properly maintained or if the dog is engaged in activities that increase the likelihood of injury. Here are some potential health concerns associated with rear dew claws:
Tearing or Snagging: The position of rear dew claws, higher up on the leg, makes them more susceptible to tearing or snagging on objects. This can cause pain, bleeding, and potential infection. Regular trimming of rear dew claws is essential to prevent them from becoming too long and prone to catching on surfaces.
Injury during Physical Activities: Dogs that engage in activities such as agility, hiking, or intense play may be at a higher risk of injuring their rear dew claws. The claws can get caught in the ground or obstacles, leading to sprains, strains, or even fractures. It is crucial for owners to monitor their dogs closely during such activities and intervene if there is a risk of injury.
Infection: Rear dew claws can be prone to infection if dirt, debris, or bacteria become trapped between the claw and the leg. Regular cleaning and grooming of the dew claws can help prevent infection and discomfort.
Impaction: In some cases, rear dew claws may not naturally shed their outer layer or have difficulty shedding it. This can lead to a buildup of dirt and debris, causing discomfort and potential infection. Regular grooming and inspection of the rear dew claws can help prevent impaction.
It is worth noting that not all dog breeds with rear dew claws will experience these health concerns. The risks can vary depending on the breed’s activity level, lifestyle, and proper care provided by the owner. Regular monitoring, grooming, and appropriate maintenance can help mitigate the potential health risks associated with rear dew claws.
