This is Buster. He has vitiligo, a rare genetic condition that causes skin and fur to lose pigment over time. Though it typically affects dogs in patches, over the course of 2.5 years, he lost his black fur and became entirely white instead. His human said the transformation started around his face before spreading to the rest of his body, and "there was a point in time where he was balding in areas until his fresh fluffy white fur grew in." The transition was completely painless, and it turns out Buster is handsome in both black and white. 14/10
