It is not necessary to get an injection if your dog scratches his paws slightly, because rabies is usually transmitted through bites, so if you scratch a scratch but there is no bleeding, you will not be infected with rabies virus. You only need to clean the wound and then use alcohol Or iodophor can be used for disinfection to avoid bacterial infection; and rabies is only contagious during the onset stage, so healthy dogs generally do not carry rabies virus.
