Treatment is a multi-modal approach involving topical therapies like lime sulfur dips and oral antifungal medications such as Itraconazole. Environmental decontamination is equally critical to prevent reinfection.

The prognosis is good, but treatment is often lengthy, taking weeks to months. Full recovery requires verifying that both the animal and the environment are free of spores.
