Extra toes on dogs, known as polydactylism, might sound strange, but it’s a fascinating genetic trait in certain breeds. While most dogs have five toes on their front paws and four on their back, some are born with additional digits. These extra toes can vary in size and position and are generally harmless. In some breeds, they serve a functional purpose, offering extra grip, stability, or traction. Though rare, polydactylism showcases the amazing adaptability of our canine companions and their unique abilities.

The Newfoundland is one of the most famous breeds known for having extra toes, specifically on their hind paws. These extra digits are often referred to as “water toes” and are believed to have evolved to help these large, working dogs swim more efficiently. As the breed was originally used for water rescue and retrieving, the additional toes function much like flippers, providing better traction and balance in slippery conditions. These extra toes also help the dog get a better grip on icy or wet surfaces, making them more effective swimmers and rescuers. While not every Newfoundland has extra toes, it’s still a prominent feature in the breed, and it’s considered an asset for those still involved in water rescue work.

The Australian Shepherd is another breed that occasionally exhibits polydactylism, particularly on its hind paws. While not common, some Australian Shepherds are born with extra toes, a trait that likely helped their ancestors maintain better traction on rough, uneven terrain while herding livestock across rocky hills or steep slopes. The additional digits would have provided better stability and grip in challenging environments, enhancing their agility and efficiency. While the trait is rare today and doesn’t serve a major functional purpose, it’s a fascinating reminder of the breed’s working history and adaptability to tough conditions.

The American Coonhound, a breed known for its hunting and tracking abilities, sometimes exhibits polydactylism, particularly with extra toes on its hind feet. Though not a defining characteristic of the breed, some Coonhounds are born with extra digits. The presence of extra toes may have historically helped them maintain balance and stability in rugged, forested terrain, particularly when chasing prey. The extra toes provided a wider surface area to help these dogs stay grounded on uneven or slippery surfaces. Though it’s not as common as in other breeds, some owners believe that polydactylism could have played a role in the breed’s success as a tracker and hunter in difficult environments.
Chihuahuas

Chihuahuas, the tiny but mighty breed, can sometimes be born with extra toes, particularly on their back paws. This trait, though rare, occurs in certain lines of Chihuahuas and is often seen as a quirky but harmless characteristic. Like other breeds with polydactylism, the extra toes don’t serve a significant functional purpose in modern-day Chihuahuas, but they may have provided some advantages for their ancestors. The extra toes likely gave these dogs a better grip on rough terrain or helped them maneuver through obstacles when performing their original tasks, such as guarding or hunting small game. Despite the extra toes not being a widespread feature in Chihuahuas, they remain an intriguing and adorable aspect of the breed for those lucky enough to see them.
St. Bernard

St. Bernards, large and strong working dogs originally bred to help rescue travelers in the Swiss Alps, occasionally exhibit polydactylism, particularly on their hind paws. While this trait is not as common in the breed as in others, it is believed to have been useful when the dogs were working in harsh mountain environments. Extra toes may have provided these massive dogs with better traction on the steep, icy, and snowy slopes they often navigated while performing rescue operations. Though the extra toes are not a defining characteristic, they likely played a role in enhancing the dogs’ grip and stability in their challenging environment, allowing them to perform their rescue duties more effectively.

The Border Collie, known for its incredible intelligence and herding skills, can sometimes exhibit polydactylism, especially on its front paws. Extra toes in Border Collies are believed to have been beneficial for the breed’s original purpose of herding sheep across rocky, uneven terrains. The additional digits might have given these dogs added traction and stability, improving their ability to navigate difficult landscapes with speed and precision. Though polydactylism is not a widespread trait in the breed, it highlights the Border Collie’s remarkable adaptability to the challenging environments where they worked.

The Great Pyrenees, a majestic working breed, occasionally have extra toes, typically on their hind feet. This breed was originally bred to guard livestock in the Pyrenees Mountains, and the extra toes are believed to have provided them with better grip and stability when walking on rugged, rocky terrain. The additional digits likely gave the Great Pyrenees better traction, which was especially important when navigating the mountainous, snow-covered slopes. While not all Great Pyrenees dogs exhibit polydactylism, those that do may have a slight advantage when it comes to maintaining balance in the challenging environments where they were bred to work, such as high altitudes and rough terrain.
The Paws Have Spoken Extra Toes And All!

Extra toes on dogs are a unique and fascinating feature that many people don’t realize exists. While it might seem like a random mutation, polydactylism in certain breeds often ties back to their history and original purpose. Whether helping dogs swim, climb, dig, or navigate rugged terrain, these extra digits serve a functional purpose. So, the next time you spot a dog with a few extra toes, just remember: they’re not only walking through life with more style—they’re doing it with a bit more traction, too!
