After being scratched by a dog, disinfect the wound as soon as possible. You can use saline, alcohol, and iodophor. If you don’t have the above disinfectants around, you can use soapy water and white wine instead. Then disinfect the scratched area. Carefully disinfect and wipe until the bleeding stops. Afterwards, you will decide whether to receive rabies vaccine based on your own physical condition and the physical condition of your dog.
