The skin is slightly red if bitten by a dog.

Once bitten by a dog, although the skin is not broken, you still need to immediately wash the wound with soap and water for 10-15 minutes. Full washing is mainly to prevent the rabies virus from breaking through the epidermis. After entering the human body, the rabies virus is infected through the blood of the saliva of the dog with the virus strain. If there is no bleeding, there is no blood transmission route. Generally, the infection will not occur, but some capillaries may rupture. The amount of bleeding is very small, so if you are bitten by a dog, it is recommended to get a rabies vaccine to reduce the risk of illness.
