Here we present three clinical cases of canine dermatophytosis resolved with topical propolis treatment that involved alopecia and well-demarcated erythematous lesions. These cases were positively identified by direct observation of samples from the affected zones with 10% KOH. Each sample was cultured, leading to the isolation of Microsporum gypseum in one case and Microsporum canis in the other two cases. The animals’ subsequent treatment included bathing using a commercial soap with propolis every seven days for 3 to 8 weeks, as well as the use of a propolis-containing ointment elaborated in our laboratory, which was applied to the lesions once a day for three weeks. From the second week of treatment, all cultures were negative. At the end of treatment, all cases displayed full recovery of the injuries and hair growth in these areas. In these clin-ical cases, treatment with propolis was effective, supporting the use of propolis as a promising natural alternative with no known collateral effects.
