It is recommended to use a topical spray containing terbinafine. If the dog's fungal skin disease is relatively large or the infection lasts for a long time, oral medications, such as those containing itraconazole, need to be used. Antifungal topical shampoo can also be used during treatment to shorten the treatment cycle.

One characteristic of dog ringworm is that it is highly contagious and can be transmitted not only to dogs but also to humans. Therefore, once the owner discovers that his dog at home has ringworm, he must be isolated separately. It is recommended that dogs be kept in separate cages, and food bowls, water basins, toys and other supplies should be used alone and should not be mixed with other dogs.
