In the world of canine anatomy, there exists a fascinating variation that can often go unnoticed by casual observers: the number of toes that dogs possess. While most dogs have a standard configuration of four toes on each foot (including a dewclaw, which is often not counted as a functional toe), some dogs may have either 18 or 20 toes in total, depending on whether they exhibit a genetic trait known as polydactyly. In this blog post, we delve into the differences between dogs with 18 and 20 toes, exploring their unique anatomical features, potential health implications, and any notable breeds that commonly exhibit these traits.
Anatomical Differences:
At first glance, the primary difference between dogs with 18 and 20 toes is, of course, the total number of toes they possess. Specifically, dogs with 18 toes will have four toes on each of their front paws and three toes on each of their hind paws, excluding dewclaws. In contrast, dogs with 20 toes will have four toes on each paw, including the hind paws, again excluding dewclaws.
Polydactyly, the term used to describe the condition of having extra toes, can manifest in varying degrees. Some dogs may have just one or two extra toes, while others may have multiple extra toes on multiple paws. This variation in the number and location of extra toes can lead to a wide range of anatomical differences, from subtle to quite pronounced.
Potential Health Implications:
While the presence of extra toes is generally considered harmless and cosmetic, there are some potential health implications to consider. Extra toes can sometimes cause problems with mobility or gait, especially if they are large or misshapen. In some cases, they may also be prone to injury or infection. Additionally, if a dog’s dewclaws are not properly trimmed or cared for, they can also become problematic.
It’s important to note that not all dogs with extra toes will experience these health issues. Many dogs with polydactyly lead happy, healthy lives with no adverse effects from their extra toes. However, it’s always a good idea to have your dog examined by a veterinarian to ensure that any extra toes are not causing any problems.
Notable Breeds:
Certain breeds of dogs are more likely to exhibit polydactyly than others. Some of the most notable breeds that commonly have extra toes include:
- Catsahogs (a hybrid breed of Catahoula Leopard Dog and American Bulldog): This breed is known for its high prevalence of polydactyly, with some individuals having as many as six toes on each paw.
- Newfoundlands: This large, gentle breed is also known to sometimes exhibit polydactyly, although it is less common than in some other breeds.
- Great Pyrenees: These majestic dogs, known for their thick, white coats and loyal personalities, can also occasionally be born with extra toes.
Conclusion:
In conclusion, the difference between dogs with 18 and 20 toes lies in the number of toes they possess on their hind paws, which is a result of the genetic trait of polydactyly. While this anatomical variation may be subtle, it can lead to a range of unique features and potential health implications. It’s important to have any dog with extra toes examined by a veterinarian to ensure that they are healthy and happy.
