Abstract

A 4-year-old female American cocker spaniel was hospitalized with 6 months prolonged dermal problems in The Veterinary Medical Teaching Hospital of Seoul National University. Initial noticed signs by owner of this dog were rashes and papules on ear part and they were spreaded whole body. On initial physical examinations, papules, pustules, crusts, and erythema were presented on whole body. Diameters of focal scaly and erythematous alopetic lesions were varied ranging 1 to 4cm. Skin scraping for detecting ectoparasites and wood's light examinations for dermatophyte were negative. Any bacteria were not detected but Malassezia pachydermatis was detected on cytological examination and fungal culture. The dog was treated with Itraconazole (5mg/kg, q12h) and Cephalexin (20mg/kg, q12h) orally and then bathed with 2% chlorhexidine shampoo twice per week for 5 weeks. From 12 weeks after starting therapy, all dermal problems were disappeared although some mild pyoderma were once relapsed. Regular chlorhexidine bathing treatment so far has been continued for preventing recurrence.
