The rarest Doberman color is white. White Dobermans result from a genetic variation known as albinism, which inhibits the production of pigment in their coat, eyes, and nose. White Dobermans are not recognized in official breed standards and are typically a result of poor breeding practices. White Dobermans may have potential health issues linked to albinism, such as poor vision, sensitivity to sunlight, and a
significantly increased risk of skin tumors.
