A 10-week-old Dalmatian puppy was presented for evaluation of plaques and eschars limited to the black-haired markings on the dorsum of the body. The plaques and eschars were of acute onset. Histopathologic evaluation revealed epidermal, adnexal, and vascular necrosis, and subepidermal vesiculation consistent with a full-thickness burn. Because of the history of exposure to direct sunlight, limitation of plaques and eschars to black-haired dorsal skin, histopathology, and lack of another identifying cause, the lesions were attributed to a thermal burn from sunlight.
