Hereditary Nasal Parakeratosis (HNPK)

$40.00

Hereditary nasal parakeratosis (HNPK) is a disease that affects Labrador Retrievers and related breeds and leads to dry, rough, discolored crusts on the edges of the dog’s nose. The disease results from a mutation that causes the nose to dry out and can lead to chronic irritation and inflammation of the skin on and surrounding the dog’s nose. Symptoms of the disorder appear in young dogs typically between the ages of around 6 months to 1 year of age. In more severe cases of the disease, cracked skin around and on the tip of the nose can become infected and require medical attention. In later stages, the disease can also affect nose pigmentation with nose skin color changing from dark to lighter shades of color. Once diagnosed, continuous care is required to reduce the occurrence of crusting on and around the dog’s nose using topical treatments.

A (CLEAR/NORMAL): These dogs have two copies of the normal gene and will neither develop HNPK nor pass this mutation to their offspring.

B (CARRIER/NOT AFFECTED): These dogs have one copy of the normal gene and one copy of the mutation associated with this disease. They will not develop HNPK but will, if bred, pass the mutation to 50% of its offspring, on average.

C (AT RISK/AFFECTED): These dogs have two copies of the mutation associated with this disease which results in discolored crusts on the edges of the dog’s nose that can become infected and require further treatment.
