A 3-year-old female Siberian husky dog is presented for the complaint of ‘crusties’. The owner reports the dog has pruritic crusty lesions on the face and ears. On dermatological examination, the lesions around the eyes are symmetrical, and similar lesions are present on the ear margins, chin, ears, footpads, and pressure points. The skin is thickened and hyperkeratotic crusting is present. The dog is healthy otherwise. The dog is fed a complete and balanced diet. Two littermates, owned by other people, have similar lesions.
