How to treat ringworm on a dog's face?

Dog facial ringworm is mainly caused by skin fungal infections, with common fungi such as Trichophyton mentagrophytes and Microsporum canis. Treatment usually involves topical sprays and internal medications. However, if the infection is near the mouth, external treatments are not recommended. Instead, use internal medications containing ingredients such as terbinafine and itraconazole.

First, clean the affected area of excess crusts and secretions. Then, apply a topical medication containing terbinafine, twice or three times daily. To minimize discomfort for the dog, use a cotton swab to apply the medication to the facial area instead of spraying it directly. If the dog can lick the medication, avoid using topical sprays to prevent health risks. Instead, opt for oral medications containing terbinafine and itraconazole. Due to the specificity of antifungal drugs, use them under the guidance of a veterinarian. Generally, the medication is taken orally for one week, followed by a one-week break. Dosage adjustments should be made based on the dog's recovery symptoms.

The pathogens that cause ringworm on a dog's face mainly include Trichophyton mentagrophytes and Microsporum canis. Symptoms usually include increased skin scales, hair loss, crusting, and itching. Since fungal infections often lack specific symptoms, a definitive diagnosis usually requires tests such as Wood's lamp examination and skin hair plucking. Once diagnosed, avoid letting the dog scratch the affected area to reduce the risk of secondary bacterial infections and prevent the fungus from spreading to other parts of the body. The treatment period for this disease usually ranges from 7 to 15 days. During treatment, follow the veterinarian's instructions and report on the dog's condition regularly.
