Miscrosporum canis is one of the most prevalent species isolated from dogs and cats, and because of the serious zoonotic potential, short-term treatment regimens are preferred to prevent the spread of disease either by direct contact or through contamination of the environment. Antimicrobial photodynamic therapy (APDT) has emerged as a promising strategy able to kill effectively a wide range of pathogens in a short period with minimal morbidity . In this case report, a 7-year-old male dog was diagnosed with dermatophytosis caused by M. canis. Methylene blue-mediated antimicrobial photodynamic therapy (MB-APDT) was applied over the lesions in two sessions with an interval of 7 days. The dog successfully healed, achieving a complete clinical cure after 21 days, without reports of recurrence after a follow-up period of 6 months. Therefore, MB-APDT could be a potential ally of small animal clinicians to treat superficial fungal diseases and should be further explored in Veterinary Medicine.1-3openAccessantimicrobial agentsmethylene blueveterinary medicinetherapyskin diseasestineaArtigo de periódico3610.1016/j.pdpdt.2021.1026020000-0002-4203-1134https://orcid.org/0000-0002-4203-113436.9467.00
