Three Pembroke Welsh Corgis Presented with Skin Lesions and Systemic Signs after Commercial Shampoo Use

Abstract

Three Pembroke Welsh corgis demonstrated symptoms of depression, anorexia, and pyrexia after being washed with a commercial shampoo by a professional groomer. These dogs exhibited skin lesions including macular erythema and erythematous papules on their trunks, as well as leukocytosis and elevated C-reactive protein (CRP). They were administered prednisolone injections as part of the symptomatic treatment. Improved systemic signs and complete regression of the skin lesions were confirmed after treatment. Based on the onset and progression of the symptoms, the result of clinical examinations and the use of the same shampoo, these cases are suspected to be related to a cutaneous adverse drug reaction caused by the shampoo.
