Understanding Double Dew Claws: A Comprehensive Guide for Dog Owners

Introduction

Double dew claws, also known as accessory dew claws or polydactyly, are an anatomical anomaly in dogs where they have an extra digit on the inside of their front (occasionally, back) paws. These dew claws are vestigial structures that are remnants of an ancestral trait and are not typically connected to the bone or muscles of the paw.

Prevalence and Inheritance

Double dew claws are a relatively common occurrence in dogs, with an estimated prevalence of 5-10%. They are more common in certain breeds, such as Great Pyrenees, Saint Bernards, Mastiffs, and Briards.

The inheritance pattern of double dew claws is complex and varies between breeds. In some cases, it is an autosomal dominant trait, meaning that only one copy of the gene is needed to express the trait. In other cases, it may be an autosomal recessive trait, requiring two copies of the gene for expression.

Appearance and Location

Double dew claws typically appear as a small, claw-like toe on the inside of the paw, positioned slightly higher than the regular toes. They can vary in size, shape, and mobility, from being small and non-functional to being fully formed with nails and pads.

Types of Double Dew Claws

There are two main types of double dew claws:

• Anterior dew claws: Located on the inside of the front paws
• Posterior dew claws: Located on the inside of the back paws

Anterior dew claws are more common than posterior dew claws.

Possible Concerns

While double dew claws are generally not harmful, they can sometimes pose some concerns:

• Injury: The dew claw can get caught on objects, leading to tears or injuries.
• Infection: The dew claw can become infected if it becomes torn or punctured.
• Pain: In some cases, the dew claw may rub against the other toes, causing discomfort or pain.

Management and Care

Double dew claws do not usually require any special care or treatment. However, there are certain steps owners can take to maintain their dog's dew claws:

• Regular nail trimming: Keeping the dew claw nails trimmed can prevent them from becoming too long and getting caught on objects.
• Protection: Owners can use boots or protective wraps to prevent the dew claw from getting injured.
• Removal: In some cases, a veterinarian may recommend removing the dew claw if it is causing significant problems.

Dew Claws and Breed Standards

In some dog breeds, double dew claws are considered a desirable trait and are part of the breed standard. However, in other breeds, they are considered a fault or disqualification. Owners should consult with breed clubs and kennel organizations to determine the breed's specific stance on double dew claws.

Pros and Cons of Double Dew Claws

Pros:

• Enhanced stability: Dew claws can provide extra stability, especially on slippery surfaces.
• Grip and traction: Dew claws can help dogs grip surfaces, particularly when climbing or running.
• Historical significance: Double dew claws are a reminder of dogs' evolutionary history.

Cons:

• Potential for injury: Dew claws can get caught on objects or become infected.
• Grooming issues: Dew claws require regular nail trimming and care.
• Breed standards: Double dew claws may not be accepted in certain breeds.

Effective Strategies for Managing Double Dew Claws

• Early detection and monitoring: Regularly check your dog's paws for any signs of dew claws.
• Nail care: Trim the dew claw nails short and smooth to prevent injuries.
• Protective measures: Use boots or wraps to protect the dew claws from sharp objects or rough terrain.
• Veterinary consultation: If you are concerned about your dog's dew claws, seek professional advice from a veterinarian.

Common Mistakes to Avoid

• Ignoring double dew claws: Ignoring double dew claws can lead to injuries or infections.
• Trimming too short: Over-trimming the dew claw nails can cause pain and bleeding.
• Ignoring the breed standard: Breeding standards should be considered when making decisions about dew claw removal.

Conclusion

Double dew claws are a common anatomical anomaly in dogs that can have both pros and cons. By understanding their prevalence, inheritance, and potential concerns, dog owners can make informed decisions about their management and care. Early detection, proper nail care, and protective measures can help prevent problems and ensure the well-being of dogs with double dew claws.
