A Shih-tzu(8-year-old, castrated male) was referred to the Veterinary Medical Teaching Hospital of Chungnam National University with the history of relapsing pruritus, recurrent dermatitis. On the physical examination, generalized erythema, otitis externa, alopecia and lichenification were observed. Using Favrot's criteria for diagnishing atopic dermatitis, 7 criteria were satisfied out of 8 criteria. After treatment for infection, intradermal skin test was performed(positive allergen : Df, Dp). And then immunotherapy was performed, but clinical signs were not getting better. Next treatment of glucocorticoid shown little improvement of clinical signs, and adverse effect(diarrhea) was shown after cyclosporine application. So application of leflunomide which is used for human atopic dermatitis treatment in some case was planned. After 6 months of application of leflunomide, clinical signs were decreased gradually.
