Vitiligo is defined as an area of skin depigmentation and in dogs commonly affects the muzzle, nasal planum and areas around the eyes.
Depigmentation in this condition usually occurs in young adulthood and repigmentation may occur in some cases. The condition is characterized by loss of epidermal melanocytes.
Diagnosis is based on visual skin inspection supported by histological examination under light microscopy.
There is no known treatment for spontaneous vitiligo in dogs. The condition is not life threatening, but may be unaesthetic. The extent to which the condition affects the dog is variable, some will experience full depigmentation while others will only have a depigmented nose.
