Generally, injections are not required when a dog scratches the skin, but the wound needs to be rinsed promptly with soapy water or running water for more than 15 minutes, and then iodophor is applied for disinfection to avoid bacterial infection and wound inflammation. Dogs raised at home generally do not carry rabies virus, and rabies virus is only contagious before the onset of illness and is transmitted through bites, so there is no need to worry too much.
