Canine superficial pyoderma is mainly caused by Staphylococcus pseudintermedius and S. schleiferi on and/or in the epidermis dermis and the follicle. Due to the increased frequency of the isolation of drug-resistant bacteria from skin lesions, therapy for canine superficial pyoderma has become highly complicated. Accordingly, the Guideline Committee of the Japanese Society of Veterinary Dermatology has attempted to develop a guideline for the treatment of canine superficial pyoderma in Japanese veterinary practice. We referred to reviews and guidelines concerning canine skin infection which were mainly published in the US and European countries, and collected additional papers. Based on the findings, it is difficult to propose a guideline for Japanese practitioners at this moment, since evidence for the practice is quite limited. Through this research, we have gained an understanding of the current problems concerning therapies for canine superficial pyoderma. This article tries to present a clinical indication rather than a guideline based on previously published evidence. In addition, several issues facing current practice are also discussed.

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.
