Plain-English summary
A 7-year-old male dog was diagnosed with a skin infection caused by a fungus called Microsporum canis, which can spread to other pets and humans. To treat this condition, the vet used a special light therapy combined with a dye called methylene blue, applied over the affected areas in two sessions a week apart. The dog showed significant improvement and was completely healed within 21 days, with no signs of the infection returning after six months. This treatment could be a helpful option for vets dealing with similar skin infections in pets.

Abstract
Dermatophytosis is a superficial skin infection that widely effects companion animals. 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.
