If the skin is bitten by a dog at home, you need to flush the wound with soapy water or saline for 10 to 15 minutes, then squeeze out the blood from the wound, and finally apply alcohol or other disinfectant. If the dog at home has been vaccinated against rabies, he will not be infected with rabies if bitten by the dog. If he has not been vaccinated against rabies, it is best to go to the hospital to get vaccinated within 24 hours.
