Nasal Depigmentation




Condition Overview

Nasal Depigmentation, also called Dudley nose, is a syndrome of unknown cause that may be a form of vitiligo. Depigmentation primarily affects the skin of the nose where hair is absent.


A nose that is solid black at birth gradually fades to a chocolate brown, or in the case of complete depigmentation, to a pinkish white. Some dogs experience remission in which the nose spontaneously becomes darker.


Information needed.


Diagnosis is made by physical examination.


The lack of pigment on the nose is primarily a cosmetic problem and is considered to be a conformation fault in the show ring. A number of home remedies have been advocated, but their success is questionable. Sunscreen, helps prevent ultraviolet injury to dogs who lack pigment.


Information needed.


Please contact your veterinarian if you think your pet may have this condition.
