nasal depigmentation
occurs in dogs with a normal, darkly pigmented nasal planum at birth which later fades to brown or a pale gray-white. Called also Dudley nose, the cause is unknown, but it may be a form of vitiligo. A seasonal loss of pigmentation, usually during winter months, occurs in some breeds, including Siberian huskies, Golden retrievers, Labrador retrievers and Bernese mountain dogs. Called also snow nose.
