The Kennel Club has approved a new official DNA testing scheme for hereditary nasal parakeratosis (HNPK) in the Labrador Retriever. HNPK is an inherited autosomal recessive disorder that causes their nose to dry out, leading to chronic inflammation and irritation of the nose’s skin.

Caroline Kisko, Kennel Club Secretary, said, “We are pleased to be announcing this new DNA test for the breed, which will assist in responsible breeding and enable potential puppy buyers to be aware of an issue which could affect their chosen breed, and ultimately protect and maintain the health of the breed.”

As HNPK is a recessive disorder, a dog must have two copies of the defective gene in order to develop the disorder. If two healthy carriers are bred, their pups will have a 25 per cent chance of developing HNPK.

The result of the DNA test will appear on any new registration certificate issued for the dog and on the registration certificates of any future progeny of the dog, and also on the Health Test Results Finder on the Kennel Club website.
