In mildly affected animals, the only sign is the formation of asymptomatic comedones (blackheads) which are dilated hair follicles on the midline of the back.
Bilaterally symmetrical hair loss and excessive scaling especially around face, head, ears and trunk.
Single to multiple raised, hairless, lobulated white to pale pink skin or sometimes pigmented skin masses which may ooze an oily white material. Masses range in size from ¼” – 1” in diameter.
Affected skin is reddened, scaly, and may lose hair. With continued sun exposure thickened skin, red bumps, plaques, and nodules develop which may become ulcerated and crusty.
Lesions occur most commonly on the trunk, the legs, the digits (toe), the scrotum, the lips, the anus, and the nose. The lesions are typically ulcerated or cauliflower-like in appearance, bleed easily and are typically solitary.
Usually an acute onset of nail loss. Initially, one or two claws are lost, but over a course of a few weeks to several months, all claws slough.
Includes: lethargy, weight loss, fever, decreased appetite, and coughing.
bruising, localized areas of necrotic (dead) skin and skin ulcers especially in areas such as the ear pinnae, lips, mouth, paws, tail, and scrotum.
Often involve the gums, tongue, palate, throat and lip as well as the nose, eyelids and even the eye. These lesions usually appear as white to gray, cauliflower-like masses.
Skin lesions include plugged, dilated pores/follicles, crusts, and crusty plaques especially on the ventral and lateral chest and abdomen.
