If the skin is scratched by your dog and there is no bleeding, you need to clean the wound immediately, rinse it with running soapy water for more than ten minutes, and then apply alcohol or iodine to the wound for disinfection. Under normal circumstances, your own dog will not carry the rabies virus, and the rabies virus is only contagious during the onset stage. It is generally transmitted through bites, so you will basically not be infected if there is no bleeding from the bite.
