Some dogs have extra toes that make their paws look strikingly different, but the feature has several possible explanations. Learn which breeds are associated with extra digits, what to look for, and why a paw clue cannot establish a dog’s pedigree.
What counts as an extra toe on a dog?
Most dogs have four weight-bearing toes on each paw. A dewclaw is a smaller digit set higher on the inside of the leg; it does not usually touch the ground when a dog stands. Front dewclaws are common, while hind dewclaws are less widespread. Some dogs have two dewclaws on one or more legs, creating the appearance of extra toes.
People may use “extra toes” to describe any digit beyond the usual four, but the term can refer to different structures. A rear dewclaw may be attached firmly to the leg or connected by softer tissue, and the number and placement of digits vary. Looking at the paw can suggest what is present, but a veterinarian can assess its structure if there is a concern.
Which dog breeds are known for extra toes?
The Norwegian Lundehund is the breed most famously associated with multiple toes. Breed descriptions identify six toes on each foot, along with other distinctive features. The Great Pyrenees is another breed in which double rear dewclaws are a recognized trait. Some other large or mountain-type dogs may also have rear dewclaws, though the feature is not exclusive to any one breed.
These associations are useful clues, not a way to identify an individual dog with certainty. Mixed-breed dogs can have extra digits, and a dog from a breed associated with them may not display the same visible pattern. Breed standards and traits can also differ by kennel club or region.
| Breed or group | Commonly noted paw trait | What the trait can indicate |
|---|---|---|
| Norwegian Lundehund | Multiple toes on each foot | A characteristic associated with the breed |
| Great Pyrenees | Double rear dewclaws | A recognized breed feature |
| Other dogs | One or more rear dewclaws | Natural variation; not a breed diagnosis |
How to examine a dog’s paws safely
Start by observing the dog while it stands on a non-slip surface. Look at each paw from the front and side, then gently check the inner side of the lower legs for dewclaws. Compare left and right paws: the digits may not be identical on every leg. Do not force a dog to hold still or pull at a toe, especially if it seems uncomfortable.
Note where each digit sits, whether it contacts the ground, and whether it appears firmly attached. These observations can help describe the paw, but they cannot establish the dog’s ancestry. If the dog resists handling, or a digit looks swollen, injured, or painful, leave the examination to a veterinary professional.
Why extra toes do not prove a dog’s breed
A visible trait is only one piece of an identification puzzle. Dogs from different breeds can share paw features, while dogs of the same breed can vary in appearance. Extra digits may be inherited, but their presence alone does not show which breed contributed them or in what proportion.
A photo has further limits: fur, posture, camera angle, and image quality can obscure the number or attachment of toes. Even a clear image cannot prove pedigree, give reliable DNA percentages, or determine a dog’s health or temperament. If ancestry matters, documented lineage or an appropriately selected DNA test may provide additional information; each has its own scope and limitations.
When should a veterinarian check an extra toe?
An extra digit can be a harmless physical variation, but its location and attachment matter for care. A dewclaw that catches on objects, grows in an unusual direction, or is difficult to keep trimmed may need attention. Watch for limping, licking, bleeding, redness, swelling, discharge, or a sudden change in how the dog uses its paw.
Contact a veterinarian if a toe appears painful, has been injured, or repeatedly snags. Avoid cutting or removing a digit at home. A veterinarian can examine the paw and explain whether routine monitoring, nail care, or treatment is appropriate for that specific dog.
What other clues help with visual breed identification?
For a more balanced visual assessment, consider the dog’s overall build, coat, ears, tail, head shape, and proportions alongside its paws. Record several observations rather than treating one unusual feature as decisive. Age, grooming, body condition, and individual variation can affect how those traits appear.
Use breed clues to form possibilities, not a verdict. Extra toes can be a memorable feature and may point toward breeds known for particular paw patterns, especially the Norwegian Lundehund or Great Pyrenees. But the most accurate description of an unknown dog should acknowledge uncertainty and avoid turning a single physical trait into proof of breed, health, or behavior.
