Labradors were also bread to be well-suited for water. These breeds were both the product of a fishing culture that needed dogs who would be willing to dive into the water to save fishermen who had been swept overboard. This is certainly the case for Newfoundlands and Portuguese Water Dogs. While some dogs were needed for guarding, herding, and hunting, other dogs were used in more aquatic-based roles. Over the centuries that mankind and dogs have been coexisting, humans have been breeding dogs to perform specific jobs.
Why Do Some Dogs Have Webbed Feet?Ĭharles Darwin notes in his book The Variation of Animals and Plants Under Domestication that some dog breeds have varying degrees of webbing between their toes.Īccording to Darwin, this webbing is the process of selective breeding, though not with intentionality when it comes to webbing in particular. It is for similar reasons that some dogs have developed webbed feet, either through a natural evolutionary process or through deliberate selective breeding. The extra surface area distributes weight more evenly and makes it easier for animals with webbed toes to walk on the ground where non-web-toed creatures might struggle. What you may not realize is that webbing also helps animals navigate muddy or slippery surfaces. The webbing creates a larger surface area to push against the water and propel the animal forward. However, the retention of webbed feet is, in some cases, a deliberate evolution to give land-dwelling animals that spend a lot of time in the water, such as ducks, swans, and geese, an advantage in water and on slick surfaces.Īs you probably know, webbed feet make it much easier for an animal to swim. News Medical observes this birth defect in children who are born with partially or sometimes fully webbed fingers and toes. This sometimes happens unintentionally if the embryo doesn’t develop as it should. However, some creatures will retain this webbing either fully or partially once they’re born. This process releases genetic coding that identifies cells programmed to die off in later stages of development and begins this elimination.
This happens through a process called apoptosis. Most land-dwelling embryos lose this webbing as they develop. This is an evolutionary hold-over from when most mammals needed some advantage in an aquatic environment.
WEBBED FEET HUMANS SKIN
If you look at a duck’s feet, they still have the same bones and toe structures that dogs and humans have, just with extra skin stretched between them.Īccording to Epigenetic Principles of Evolution by Nelson Çabej, most land animals, including dogs and humans, have webbed fingers and toes when they are developing in the womb. Webbed feet are the result of membranes that are stretched between the phalanges that make up toes. Read on to learn more about what causes webbed feet in dogs, what Rottweilers were bred for, and why they generally don’t need extra webbing between their toes. Unlike some other working dogs, Rottweilers have never been used much in the water. This explains why Rottweilers don’t generally have webbing between their toes. The extensive webbing that can give a duck-like appearance, though, is generally only present in dogs that were bred specifically to work in water. Technically, all dogs (and even humans) have webbing to some extent. Webbing on a dog’s feet is an interesting trait. Rottweilers can have some webbing between their toes, but this is generally the result of being crossed with another breed more suited for the water like Labradors or Newfoundlands. The breed standard for Rottweilers doesn’t include webbed feet. Read on below to find out the answers and see how they relate to each other and the history of this noble breed. Despite this, there is still a lot of misconception out there surrounding this beautiful breed.Īre they the vicious animals’ people say they are? What were they first bred for? And do they have webbed feet or not? Rottweilers are a well-known and popular breed with striking features and a long, noble history of service and friendship with mankind. Why Don’t Rottweilers Have Webbed Feet?.
