If the skin is not broken after a dog bite, it proves that the skin is not damaged, and even if the dog’s teeth harbor rabies virus, it will not invade the human body through the skin and cause rabies attacks, so this situation does not require rabies vaccination, nor tetanus shots. However, it is important to note that although the skin is not visible on the surface, it is advisable to use some strong light such as a flashlight or cell phone light to irradiate the local bite to determine whether there is a broken skin, or you can additionally use disinfectant water to test it, you can use some alcohol, iodine volts or hydrogen peroxide to disinfect the bite, if there is local irritation and pain, it proves that there is epidermal damage. In this case, rabies vaccination is necessary.
