It is mainly caused by fungal infection and needs to be treated with antibacterial drugs. You can remove the hair on the affected area and then apply an ointment containing terbinafine. The treatment cycle is long, so you need to take the medicine on time and disinfect the home well.

If the disease is widespread, in addition to applying ointments, you also need to take a medicated bath every 3 days and inject antifungal injections once a week for treatment.

Pet owners can thoroughly clean their living environment, use disinfectant to wipe furniture and mop the floor. Daily necessities used by affected dogs should also be soaked or scrubbed with disinfectant and then fully dried and disinfected in the sun. Keep the room well ventilated and dry. In humid weather, you can adjust the room temperature and dehumidify to avoid the proliferation and spread of fungi.
