What is the reason for the presence or absence of dew claws in certain dogs?

What are dew claws in dogs?

Dew claws are the small, extra toes located on the inner side of a dog’s paw, slightly above the rest of the toes. They are often referred to as "thumbs" or "fifth toes." Unlike the other toes, which are firmly connected to the leg bones, dew claws are attached by a small piece of skin and have no direct connection to the skeletal structure. These claws are present on both the front and hind legs of some dogs, but not all.

Types of dogs with dew claws

There are two types of dogs that commonly have dew claws: those with single dew claws and those with double dew claws. Single dew claws are most often found on the front legs and appear as small, digit-like appendages. Double dew claws, on the other hand, are found on the hind legs and consist of two separate claws, resembling a miniature set of rear toes.

Dogs without dew claws: an overview

While many dogs possess dew claws, there are numerous breeds that do not have them. In these breeds, the dew claws have either been bred out over time or were never present to begin with. Dogs without dew claws have a more streamlined appearance, as their paws lack the extra protrusions. It is important to note that the absence of dew claws does not impact a dog’s ability to walk, run, or perform everyday activities.

Evolutionary purpose of dew claws

The purpose of dew claws in dogs is a subject of debate among researchers and experts. One theory suggests that dew claws were once functional and aided in gripping and climbing, especially for dogs that roamed rugged terrains or engaged in activities such as hunting or herding. However, as dogs evolved and their lifestyles changed, dew claws became less necessary for survival and gradually lost their purpose.

Factors influencing dew claw presence

The presence or absence of dew claws in dogs is influenced by several factors, including genetics, breed standards, and selective breeding practices. Some breeds have a higher likelihood of having dew claws due to their genetic makeup, while others have had their dew claws removed for aesthetic reasons or to prevent potential injuries. Additionally, different kennel clubs and breed organizations may have varying guidelines regarding the inclusion or exclusion of dew claws in breed standards.

Genetic basis of dew claw expression

The inheritance of dew claws in dogs is complex and involves multiple genes. It is generally believed that the presence of dew claws is a dominant trait, meaning that if one parent possesses dew claws, there is a higher chance the offspring will as well. However, certain breeds have been selectively bred to eliminate dew claws, resulting in a recessive trait. Consequently, the expression of dew claws can vary even within the same breed.

Breeds with dew claws as a breed standard

In some dog breeds, dew claws are considered an essential characteristic and are required by breed standards. For example, the Great Pyrenees, Briard, and Beauceron breeds all have breed standards that explicitly state the presence of double dew claws on the hind legs. These dew claws are considered part of the breed’s identity and are actively maintained and preserved by breeders.

Breeds with dew claws as a disqualification

Conversely, there are dog breeds where the presence of dew claws is considered a disqualification in conformation shows or breed competitions. Breeds such as Boxers, Doberman Pinschers, and Rottweilers fall into this category. In these breeds, dew claws are seen as a deviation from the breed standard, and dogs with dew claws may be penalized or disqualified from participating in certain events.

Dew claws and dog breed development

The presence or absence of dew claws can play a role in the development of specific dog breeds. Breeders may choose to remove dew claws in order to conform to breed standards or to reduce the risk of injuries that could occur during various activities. Conversely, some breeders may actively promote the retention of dew claws to maintain the breed’s historical characteristics or preserve the dog’s working abilities.

Pros and cons of dew claws in dogs

Dew claws have both advantages and disadvantages. Proponents of dew claws argue that they provide dogs with additional stability, especially when navigating rough terrains or engaging in activities that require strong grip. They believe that dew claws can aid in climbing, grasping objects, and even provide some protection to the leg joints. However, opponents argue that dew claws can be prone to injuries, such as catching on objects or tearing. Additionally, they claim that removing dew claws can prevent potential health issues and reduce the risk of injuries in the long run.

Dew claw removal: ethical considerations

The topic of dew claw removal is a subject of ethical debate. While some breeders and dog owners choose to have dew claws removed for various reasons, such as aesthetics or to prevent potential injuries, others argue that the procedure is unnecessary and can cause undue pain and distress to the dog. It is crucial for dog owners and breeders to carefully consider the ethical implications of dew claw removal and consult with veterinarians to make informed decisions that prioritize the welfare of the animal.

Caring for dogs with dew claws

Dogs with dew claws require regular and appropriate care to ensure their well-being. It is important to regularly trim the nails of both the main toes and the dew claws to prevent overgrowth or injury. Additionally, dew claws should be monitored for potential issues, such as infection or ingrown nails. Regular grooming and inspection of the paws can help identify and address any problems early on. Furthermore, dog owners should provide suitable surfaces for their dogs to walk on, as rough terrains can put extra strain on the dew claws, potentially leading to injuries.
