Lesions, which consist of scaly, thickened, hyperpigmented skin surrounding a necrotic ulcer, begin at the apex of the ear and spread along the concave surface. Eventually, necrosis may deform the margin of the pinna. Pentoxifylline (15–20 mg/kg, bid-tid) and/or the combination of tetracycline (250 mg tid for dogs <10 kg; 500 mg tid for dogs >10 kg) or doxycycline (5 mg/kg bid) and niacinamine (250 mg tid for dogs <10 kg; 500 mg tid for dogs >10 kg) have been anecdotally reported to be efficacious in some cases. Topical glucocorticoids are also an option but must be used carefully because of their atrophogenic effects.
