After dogs are infected with fungi, if the symptoms are not serious, you can use Dacronine, because the main component of Dacronine is miconazole, which has a certain therapeutic effect on fungal skin diseases. If there is no effect after using it for a few days, you need to change to a pet-specific dermatological ointment, otherwise it will easily aggravate the condition. You can use Pitfen, etc. If the symptoms are serious, you can directly take a medicated bath. Pay attention to keeping the environment clean and hygienic, deworm the dog regularly, and dry the dog's hair after bathing to avoid fungal infections.
