There is no bleeding and a little bit of redness after the dog bites

The redness of the skin may be damaged. If it is not visible to the naked eye, it does not mean that the skin is intact. The wound should be disinfected immediately, rinse the wound with soap and water for more than 20 minutes, and then Apply iodine and medicinal alcohol repeatedly and disinfect 2-3 times. If it is a domestic dog, has been vaccinated on time, and is in good health, there is no need to worry.
