Digital hyperkeratosis health testing for Dogue de Bordeaux

The Dogue de Bordeaux is a large, stocky, and very muscular dog breed, known for its grumpy-looking yet endearing face and a no-nonsense demeanour. Originally bred for hunting, protection of livestock and families, these dogs were prized for their boldness and confidence.

Despite their imposing appearance and protective nature, Dogue de Bordeaux are affectionate companions who form strong bonds with their families. They can be wary around strangers but tend to be obedient, calm, and well-mannered when socialised properly. Their exercise needs are moderate, and they handle reasonable periods alone well if their physical and mental needs are met.

One downside to the breed is a relatively shorter lifespan compared to other dogs, coupled with several hereditary health concerns. One such inherited condition is digital hyperkeratosis (DH), which affects the pads of their paws.

What is digital hyperkeratosis?

Digital hyperkeratosis, sometimes called hereditary footpad hyperkeratosis or "corny feet," causes the footpads to thicken and harden excessively. This abnormality makes the paw pads prone to painful cracking and splitting, increasing the risk of infections.

Some affected Dogue de Bordeaux dogs also show accelerated nail growth, resulting in weakened claws that are malformed and prone to breaking.

With attentive care involving regular foot and claw maintenance, affected dogs can lead happy, normal lives. Owners must maintain hygiene and monitor for signs of pain or infection to keep their pets comfortable and healthy.

How is digital hyperkeratosis inherited in Dogue de Bordeaux?

DH is an inherited genetic disorder caused by a mutation specific to the Dogue de Bordeaux breed. It is an autosomal recessive condition, meaning a dog must inherit two copies of the faulty gene—one from each parent—to develop the disease.

Understanding parent dogs' genetic status through DNA testing is crucial in predicting the health outcomes of their offspring. Typical inheritance patterns include:

• Affected parents: Both sire and dam affected will produce an affected litter.
• Clear parents: Both sire and dam clear will produce a clear litter.
• Carrier parents: Two carrier parents will yield approximately 25% affected, 50% carriers, and 25% clear puppies.
• Mixed status: Combinations of clear, carrier, and affected parents produce predictable mixes of carrier, clear, or affected puppies as described by genetic principles.

DNA health screening for digital hyperkeratosis

Visual inspection alone cannot determine if a Dogue de Bordeaux is clear, a carrier, or affected by DH, especially in young dogs before symptoms appear. Thankfully, DNA tests exist to identify the genetic status precisely.

In the UK, reputable vets can collect DNA samples—usually via cheek swabs or blood—from Dogue de Bordeaux for analysis at accredited laboratories. These tests detect mutations responsible for DH and classify dogs as clear, carrier, or affected.

Using these results, breeders can make informed mating decisions that help reduce the incidence of DH in future litters, promoting healthier breed populations. Though currently not mandatory in the UK Kennel Club Health Standards, use of DNA testing is strongly encouraged to maintain breed health.

Managing digital hyperkeratosis in affected dogs

If your Dogue de Bordeaux is affected, consistent paw care is essential. This includes:

• Regular moisturizing of footpads to prevent extreme dryness and cracking.
• Frequent trimming and monitoring of claws to avoid malformations and injuries.
• Prompt treatment of any cracks or infections with veterinary guidance.
• Using protective footwear during harsh weather or rough terrain walks when necessary.

With proper management, affected dogs enjoy good quality lives. Early diagnosis through DNA testing supports timely intervention and better long-term outcomes.

Responsible breeding and ownership

DNA testing for digital hyperkeratosis should be considered essential for anyone breeding Dogue de Bordeaux. Prioritising genetic health helps avoid producing affected puppies and upholds the welfare of this remarkable breed.

Prospective owners should seek reputable breeders who test for DH and other hereditary conditions, ensuring puppies have the best start in life. Responsible ownership and veterinary care remain pillars of healthy, happy Dogue de Bordeaux companions.

Understanding and using health testing encourages a brighter future for the breed, preserving their legacy as loyal, majestic dogs.
