Dog skin diseases will not heal on their own, and different treatments need to be adopted for different causes

1. Purulent and inflammatory skin diseases: You can use hydrogen peroxide to disinfect them. Apply anti-inflammatory ointment to the affected area, such as red enzymatic ointment, sulfur ointment, and Dermatitis Ping. Note that Dermatitis Ping contains hormones and should be used sparingly.

2. Caused by fungi: apply krazole, tinnitus, and dakinin ointment.

3. Caused by mites: apply sulfur ointment. Fleas and lice: You can use trichlorfon to wash, or put chlorpyrifos drops on the dog's back, or use dog and cat flea traps. Dog and cat flea traps must be left for one day after opening before use.

4. Caused by lice and fleas: You can choose medicated baths, lotions, or external sprays.

5. If eczema is caused, you can choose Sefukol. Use it once in the morning and once in the evening. Use it continuously for a week, and then observe the situation to see if further treatment is needed.
