dull black with gold accents. Acquired aurotrichia of Miniature Schnauzers is a familial syndrome in which hair along the dorsal midline changes to golden from the normal black or gray of this breed. The onset is usually in young adulthood. The change may be associated with thinning in the hair coat but no other cutaneous or systemic signs. In most dogs, coat color reverts to normal within 1–2 years.
