An ear infection, or otitis, is an inflammation of the outer, middle, or inner ear canal. Most frequently, an animal will develop otitis in the outer ear that may worsen and spread into the middle ear. Once in the middle ear canal, the inflammation can move into the inner ear or, in cases in which the otitis has originated in the middle ear, the infection can instead progress outward to the external ear.
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.
Skin lesions include plugged, dilated pores/follicles, crusts, and crusty plaques especially on the ventral and lateral chest and abdomen.
Localized, multifocal or generalized hair loss, red skin, and yellow crusting or scaling. The skin and fur may be greasy.
